Dear Friends,
Welcome to the 20th Anniversary issue of Sulfuric
Acid Today magazine. Where does the time go? It seemslike just yesterday we began compiling the first issue of
Sulfuric Acid Today. I would like to thank all of those com-
panies and individuals who were with us from the beginning
and believed in the vision of producing a sulfuric acid industry
magazine that would focus on the latest products and technol-
ogy to improve the maintenance and operations of acid plants.
What began in 1994 as a black and white newsprint tabloid
of just 16 pages has grown into a full-color glossy magazine
that today reaches sulfuric acid professionals globally. I’m
extremely proud and grateful to be part of an industry that
is willing and open to the exchange of information. I’m
looking forward to another two decades of publishing
Sulfuric Acid Today magazine as well as sponsoring
sulfuric acid roundtables and workshops in the U.S.
and Australia. I hope you find this issue both helpful
and informative.
In this issue, you will find several articles that
take a look back over the last 20 years. Be sure to
read such articles as “Sulfuric acid industry evolvesover 20 years” (page 6), “Sulfuric Acid Today revis-
its 20 years of cover stories” (page 11), “Twenty years
of safety” (page 21), “Global sulfuric acid market–a
twenty year retrospective” (page 22), “The Roberts
Company highlights accomplishments” (page 34), and

The sulfuric acid industry is mourning the
loss of Louis John Doerr, Jr., who passed away
at age 90 on December 28, 2013. A native of
Saint Louis, Mo., Lou began his education at
Washington University before active duty in
World War II came calling. Lou left school at the
start of the war to join the Navy. He flew rescue
missions in the Pacific, picking up
downed U.S. airmen at sea. After
the war ended, Lou returned to
his home in Saint Louis and his
studies at Washington University,
graduating with a degree in
Mechanical Engineering.
Lou spent time as a salesman
for Aero Tool before finding hisway to Chas. S. Lewis & Co. in
1969. Lou and three other investors
purchased the company from Jim Lewis, son
of the company’s founder, Charles Lewis.
As Chairman of the Board, Lou focused on
changing the company from a local success to
an international sensation. At the start of Lou’s
tenure, Lewis® Pumps products were sold in
the United States and Canada. Thanks to Lou’s
persistence and his many contacts throughout
the industry, within eight years Lewis® Pumpsproducts were sold in more than 90 countries
around the world. Building on that success, Weir
Minerals Lewis Pumps today has products in
use in more than 120 countries. Though Lou and
his investor partners sold the company in 1977,
Lou stayed on as the Vice President of Sales until
his retirement in 1995.
As much as Lou was instrumental in
making Lewis® Pumps a well-respected name
and sought-after brand throughout the world,
his reach was felt far beyond the walls of the
company. Lou was an avid supporter of the
British Sulfur Conference and was a
member of the British Sulfur Board
of Directors. He also teamed with
others in the industry to establish
the Sulfuric Acid Roundtable as a
way for participants to exchange
ideas and spur industry growth.
Lou was considered an expert inthe industry and his contributions
will indeed be missed.
In his personal life, Lou and his wife
Rosemary had recently celebrated their 63rd
wedding anniversary. Their five children,
numerous grandchildren, and one great-
grandchild helped complete the Doerr family–
Lou’s lasting legacy. Always active in the
community, Lou was an avid fan of local sports
teams as well as a skilled golfer and tennis player.
He actively supported St. Louis FIRST Robotics,an organization aimed at inspiring high school
students to be technology leaders with future
careers in engineering and science. Lou’s
presence within his family, his community, and
the sulfuric acid industry will be greatly missed.
The Lewis Pumps family and the sulfuric
acid industry have been deeply saddened by
the sudden passing of Robert “Bob” Borges
on January 5, 2014 at the age of 62. Bob’s
genuine nature and kind heart will be missed
by his friends throughout the industry as well
as by his beloved wife, Kathy, and their two
daughters, Liz and Margie.
Raised in Milwaukee, Wis.,
Bob graduated as a metallurgist
from Michigan Technical Institute.
He began his career with the
Falk Corporation in Milwaukee,
working on some of the largest gear
reduction systems in the world.
Bob later worked for American
Magotteaux in Nashville, Tenn.,
handling technical sales and
engineering troubleshooting.
In March of 1985, Bob made the move to
Chas. S. Lewis & Co., Inc. in Saint Louis, Mo.
Hired as a metallurgist, Bob was instrumental
in developing new materials for use in acid
pumps. Over the years, he moved through
the organization as the Vice President of
Engineering and later the Vice President ofSales & Marketing. His vast knowledge made
him a natural fit for field work, and Bob was
often called on by customers around the world
to diagnose pump problems. He revamped the
way Lewis® Pumps products were built and
tested, increasing the profitability of pumps
while also raising pump quality for customers.
Bob also helped move the company in new
directions, such as initiating the company’s first
molten salt pump and opening the door to the
company’s first sulfur recovery units.
Bob was highly respected both at Lewis
Pumps and throughout the industry. Coworkers
remember Bob as a good friend
who would always stand behind
his workers and stand up for
what was right. He was loyal and
supportive with an ever-present
eye on moving the company and
the whole industry forward. Bob
enjoyed the opportunity to share
his expertise with others, and
throughout the years, he helped
many companies solve complex
problems and improve their systems.
Retiring from Weir Minerals Lewis
Pumps in 2009, Bob continued to work in the
industry as a consultant. Outside of work, Bob
was a good golfer, always striving for his first
hole-in-one, and he had significant interest
in financial investments. He was very proud
of his family, and often spoke of his wife anddaughters. Bob’s boisterous laugh and beaming
smile always announced his arrival and will
be fondly remembered by those who knew
him. Bob was indeed one-of-a-kind and his
untimely passing has left a void that will not
soon be filled.

BRUSSELS—Chemical producer Solvay
SA has hired Credit Suisse Group to
find a buyer for its sulfuric acid unit and
approached private equity firms about
a deal that could reach $800 million,
according to people familiar with the
matter. The unit, referred to as eco services,
has annual earnings of around $110
million before interest, tax, depreciation
and amortization.
Solvay said it would explore strategic
options for the unit but did not give more
details. A Solvay spokeswoman did not
respond to a request for comment on
the details of the sale. A Credit Suisse
spokesman declined to comment.
Solvay’s eco service businessproduces and regenerates sulfuric acid,
which is used as a catalyst at refineries in
the production of high-octane gasoline.
The unit is a supplier to the largest
refineries on the U.S. West Coast, along
the U.S. Gulf of Mexico and in the U.S.
Midwest and Canada. It accounted for
9 percent of Solvay’s net sales of $4.32
billion in 2013.
Solvay Chief Executive Jean-Pierre
Clamadieu said a sale of eco serviceswould simplify Solvay and allow it to
reallocate resources to fast-growing
businesses.
“I think this business could be
qualified as a cash cow or a sustainable
cash generator to use a nice terminology,”
Clamadieu said about eco services.

VANCOUVER, British Columbia—
Kansanshi Mine says it will save about
$150 million annually once the new copper
smelter is in operation and producing
sulfuric acid as a by-product. Kansanshi
Mine, which is owned by First Quantum
Minerals Limited, says the sulfuric acid
is intended to be used in the solvent
extraction/electrowinning (SXEW)
process, thereby eliminating the need to
purchase sulfur.
Meanwhile, construction of the new
1.2 million tonnes-per-annum copper
smelter was approaching peak levels with
commissioning intended to start in the
second quarter of 2014, with the ramp-
up continuing this year. The smelter is
expected to operate at 80 percent of its
design capacity by mid-2015 and achieve
full capacity in the first quarter of 2016.

8/17/2019 Sulfuric Acid Today Spring/Summer 2014
6/56
The past 20 years have been a time
of great change, both in the sulfuric
acid industry and the world. Through it
all, Sulfuric Acid Today has been there,
helping readers navigate an increasingly
evolving global marketplace. To celebrate
the 20th anniversary of the magazine, we
asked several clients who have been with us
from the beginning for their thoughts about
the last two decades, and what they hopeis on the horizon. From new technology
to environmental stewardship, safety
enhancements to information sharing, it’s
been an impressive two decades in sulfuric
acid production. Here are just a few ways
our advertisers have seen the changes fi rst
hand.
Cmps
mc For many years, the old adage “if itain’t broke, don’t fix it” applied in acid
plants. Time and money were not spent on
comprehensive, preventative maintenance
programs. When something failed (often
catastrophically), it was fixed quickly, so
that production could resume as soon as
possible. Otherwise, maintenance was
done during scheduled turnarounds, and
not given much consideration in between.
But technological advances have changed
all that.“Twenty years ago, many customers
struggled to operate on a continuous
twelve-month run between catalyst
screenings,” Jack Harris, president of
VIP International, said. “Today, with
improved, shape-optimized catalyst, many
customers run 30 to 36 months between
catalyst screenings. The extended runtime
has promoted maintenance planners to
consider more comprehensive preventive
maintenance programs. As converterruntimes are extended, other equipment
must be examined to assure reliability
throughout the campaign. Sophisticated
and knowledgeable inspections must be
maintained. In the early 1990s, we would
respond to as many as a half a dozen
catastrophic failures in towers per year.
Today, through comprehensive inspections
and preventive maintenance practices,
these catastrophic failures are typically
avoided.”
Ed Knoll, president of Acid Piping
Technology, added, “with more emphasis
on safety and preventative maintenance,
plants no longer run piping to the point of
failure.”
These longer cycles and focus on
preventative maintenance mean that
there are more pieces to juggle at each
turnaround, as well. Plant management
wants to get the most out of each facility,optimizing both efficiency and time during
an outage. “Clients require a much more
sophisticated work breakdown schedule
for the turnaround as the focus on asset
utilization is much greater,” Doug Royster
of Central Maintenance and Welding,
Florida, said.
C sps One of the most significant changes
noted in our interviews was the businessrelationship between the sulfuric acid
producer and the service contractor.
Contractors weren’t always viewed as
part of the “team,” but as a necessary evil
required to perform the tasks the producer
was unwilling or unable to complete with
plant personnel.
“Twenty years ago, the contractor
was viewed as an outside entity and, many
times, as an expendable labor force,” said
Harris. “As one old, crusty maintenancemanager told me, ‘Son, you have to realize
you have two strikes against you when you
come through the gate as a contractor. If
you were worth your salt, you would be
working for a plant like we are.’ ”
Luckily, attitudes are changing,
providing a more productive, collaborative
and safer workplace for everyone involved.
“In the past, the contractor was generally
evaluated on the end result and was left
to his own devices as far as procedure,”
said Harris. “Today, turning a blind eye to
contractor protocol has been replaced with
collaboration in examining every aspect
of the work to assure mutual safety and
productivity. Drawing upon the strength
and expertise from each side in an effort
of cooperation and respect has transformed
an adversarial role into one of mutual
success.”
Another relationship that has changed
over the years is that between plants,
suppliers and contractors when it comes
to information sharing. Gone are the days
of secrecy, thanks to global conferences
and workshops where problems and best
practices are shared, often leading to
unexpected solutions. “Consolidation of companies has led
to increased cooperation and collaboration
between plants and suppliers. The industry
has improved itself through the sharing
of experiences,” said Bob Braun, director
of engineering at Weir Minerals Lewis
Pumps. “Conferences and seminars around
the world have facilitated significant and
valuable information transfer. This was
unheard of prior to 1990. As companies
and individuals throughout the industry
share their ideas, experiences, triumphs
and setbacks, the entire industry benefits
and grows.”
“Conferences allow a free exchange of
information, ideas and best practices to be
shared globally throughout the industry,”
Harris said. “This magazine, Sulfuric Acid
Today, has without a doubt had the largest
effect on the network of information.”
Chris Bailey, president of Roberts, a
frequent attendee at industry conferences,
shared these sentiments. “Our industry is oneof continuous learning and improvement,”
Bailey said. “My hope would be that there
continues to be communication of best
practices among sulfuric plant operators
because it is through continuous learning,
and sharing of best practices, that safer and
more efficient protocols can be developed.”
fcs m
swsp Another major change over the pasttwo decades has been a trend toward
environmental awareness and green
practices. While spurred by stricter
government regulations, many of these
initiatives, including energy recovery and
cogeneration projects, have in turn become
money savers for facilities, while also
helping to safeguard the environment.
“With more stringent government
regulations, plant designs are far more
efficient. Single absorption plants are
almost a thing of the past, being replaced
by low emission facilities that were thought
to be unachievable only a few decades ago,”
Harris said. “Some plants have further
enhanced environmental preservation by
converting waste heat into cogeneration
power plants, thereby reducing the need for
fossil fuel.”
“Energy efficiency has gone up to 95
percent on most plants with heat recovery
systems,” said John Horne, sales director,MECS, Inc. “There were about 10 reference
HRS plants in the mid 1990s, compared to
85 plus now.”
Stricter environmental regulations
have also led to innovative technological
advances that might not have otherwise
been developed. “The demand for lower
emissions has allowed our R&D to develop
and bring new catalysts and technologies
to market that would not have had much
demand unless plants were being forced toreduce emissions,” Frands E. Jensen, sales
manager, environmental for Haldor Topsøe
A/S, said. “And lower SO2 emissions
requirements will most likely continue.”
There are currently no overall international
environmental regulations in place. Each
country has its own regulations, and in
some countries specific requirements are
established for each individual plant. The
European Union is, however, in a process
aimed at establishing binding commonrules for the whole of the European Union
valid for a number of important industrial
sectors.
Steve Puricelli of the MECS
Technology Group also credits new
technologies with helping reduce emissions.
“SO2 emissions have been squeezed down
to 1-2 pounds per ton, with scrubbers
(DynaWave®) and regenerative scrubbers
(SolvR™) getting the number down to 20
ppm. And acid mist emissions have been
reduced from 0.15 pounds per ton to 0.075
pounds per ton.”
The industry must continue to change
and adapt, in order to take advantage of
new technology and meet new challenges
head-on. “As fossil fuels become more
expensive, sulfuric acid production will

become a coveted source of energy. For
this reason many new plants will beconstructed with ‘built-in’ energy recovery
features,” said John V. Orlando, P. Eng.,
senior project manager/sales for NORAM
Engineering and Constructors Ltd. But
suppliers must be ready to adapt quickly
to changing needs and environmental
standards. “Technology providers will be
called upon to provide acid plants that are
proven and reliable to operate. To achieve
these goals, more innovative designs
and modern technologies will need to be
developed and implemented.”These changes won’t stop any time
soon, either. “We expect the continuation
of lower emission levels for all types of
plants and the need to expand existing plant
capacity through improved plant, process
and catalyst design,” said Mike Fenton,
Chemetics Senior BD Manager for Acid
Proprietary Equipment. “There will also
be a need for continued improvement in
heat recovery in sulfur burning acid plants,
and greater recognition that the overalllifecycle costs of a plant and its equipment
are of prime importance.”
When all of this is taken together,
from stricter emissions standards to power
cogeneration to constantly improving
technology, the end result is a win-win
for the sulfuric acid industry and the
environment. “The improved energy
efficiency has resulted in additional
power cogeneration allowing sulfuric acid
producers to reduce energy costs, whilecontinuing to be good stewards of the
environment,” said Bailey.
ecms sc The past two decades have brought
about many changes affecting plant size,
as well. From consolidation within the
industry to cost concerns, the result is that
facilities are getting bigger. “The last 20
years have seen a significant increase in
the physical size of the plants. A typicalplant used to produce 2,500 to 3,000 tons
per day, whereas today the new plants
are producing 4,500 tons per day,” said
Doug Royster of Central Maintenance and
Welding, Florida.
MECS’ Horne echoed this sentiment.
“In the 1990s, 3,500 STPD was considered
a world class plant. Today, world class is
closer to 5,500 STPD.”
“The economy of scale trending
toward larger plants for phosphate fertilizer
production and quicker turnaround times
have changed the landscape of the sulfuric
acid market within the past decade,” said
Mike Graeff, president of Koch Knight
LLC.
Dr. Hannes Storch, vice president,
sulfuric acid/off-gas of Outotec, agrees.
“Economy of scale has resulted in larger
and larger plant sizes to keep the productioncosts down.” And Storch predicts that
further economic pressure will result in
even larger units.
As with any other major change, larger
plant size affects suppliers, too, demanding
different solutions and new equipment.
“Increased plant capacity has led to the
development of larger pumps,” said Janey
Marie Hartzell, marketing specialist, Weir
Minerals Lewis Pumps. “This has spawned
research and development efforts into new
designs as well as the investigation of newmaterials. As the industry changes, so must
any supplier hoping to stay at the top.”

cs Along with larger plants and more
complete maintenance schedules comes a
need for new products and technologies.
Many of our client companies have kept
pace with the changes in the industry,meeting the demands and exceeding the
expectations of facilities worldwide. Here,
in their own words, are some of their
most important advances over the last two
decades.
viP i VIP International has long served
the sulfuric acid industry by solving
turnaround maintenance problems. In
the last 20 years the VIP employees haveperformed almost 4,000 tower inspections.
During that same time they have handled
over 160,000,000 liters of sulfuric acid
catalyst. With this much experience under
their belts, they may not have seen it all, but
when it comes to acid plants they’ve seen
more than anyone else.
Combining experience and innovation,
VIP has focused on reducing downtime
while providing superior service, safety,
experience and productivity. The company
continues to provide new and creative
maintenance solutions for everything
from converter maintenance to tower
inspections and repair; mist eliminator
removal, cleaning and installation to
exchanger tube cleaning and sleeving;
and catalyst handling and NOx removal
to acid and sulfate neutralization. VIP is
also relied on for SO2 and SO
3 scrubbing,
packing removal, tower demolition,
distribution repair and replacement and
high temperature entry.
MeCS ic. The MECS® HRS™ system has made
practical the recovery of the last 25 percent
of the energy generated by the sulfuric
acid process as medium pressure steam.The more than 80 units in operation are a
testament to the ease of use and robustness
of this technology.
The MECS® SolvR™ technology has
opened doors to waste-sulfur recovery.
Many flue gas streams contain sulfur,
but are too dilute to recover as a usable
product. SolvR™ technology now provides
a way to recover the SO2 and process it in
a conventional sulfuric acid plant. When
SolvR™ technology is used instead of
alkali based scrubbers, waste is convertedinto a useful product.
There have been three significant
improvements made to MECS® Catalyst
over the years. The shapes have been
optimized to reduce pressure drop and to
accommodate a greater build-up of dust.
The activity has improved, allowing for
better conversion, greater acid production
or lower catalyst loadings. And thirdly,
new formulations have allowed for lower
operating temperatures, which translate to
higher conversion or the ability to process
higher concentrations of SO2.
Mist eliminator technology has also
been improved. The MECS® Brink® XP™element and Brink® AutoDrain™ features
are the first major steps forward in new
mist eliminator design. These elements are
more efficient, operate at lower pressure
drop and significantly reduce maintenance
and operating issues by eliminating seal
cups and drain legs.
MECS® ZeCor® Alloys have opened
the door to innovative distributor designs
like the UniFlo® Acid Distributor that
improves the performance of sulfuricacid towers and at the same time reduces
maintenance. ZeCor® has also made tower
replacements a much more manageable task
during a routine shutdown and provides the
potential for easier maintenance repairs
over the life of the tower.
MECS® Operator Training Simulators
(OTS) for sulfuric acid plants have
brought operator training into the 21st
century. MECS has created a suite of
training simulators that are considered
the ‘best-in-class’ method to prepareoperators for real world situations such
as emergency scenarios, troubleshooting
and process optimization. The benefits of
the OTS include greater student interest
and participation, as well as a significant
increase in long-term knowledge retention.
All of these equate to a greater return on
the customer’s investment in t raining time.
h tpsø On the catalyst side, Haldor Topsøehas developed and introduced several new
types of catalysts to meet the needs of
facilities around the world.
VK69™, the first cesium catalyst
type tailored for lean gases, has with its
A major advancement in catalyst handling isVIP’s patented dust-free loading system.
MECS ® ZeCor ® Alloys have made towerreplacements a more manageable taskduring a routine shutdown and provides

unsurpassed performance helped numerous
clients achieve lower emissions and higher
production.
The VK-WSX™ catalyst was
developed as a low-temperature catalyst
for the last bed of wet sulfuric acid
(WSA) plants, meaning that up to 99.7
percent conversion can be achieved insingle contact WSA plants. VK-WSX™ is
installed in several WSA plants.
The VK38™ 25 mm Daisy dust
protection catalyst allows bigger penetration
depth of dust particles into the 25 mm Daisy
layer. The resulting higher dust capacity
yields significant savings in blower energy
and allows plants to lengthen the campaign
compared to standard size catalyst.
After installing cesium catalyst, our
VK-701 LEAP5™ is the next step for
achieving even higher conversion. VK-
701 LEAP5™ uses the new LEAP™
technology to circumvent the transport
deficiencies in the molten phase and
improve the amount of vanadium in the
V+5 form.
On the technology side, the
development of the WSA-DC™ (double
condensation) has been one of our major
achievements in recent years. The WSA-
DC™ is a double condensation wet gas
technology that allows combining the high
energy efficiency of the WSA technology
with very high SO2 conversion efficiency
of the double contact principle. WSA-
DC™ plants can be designed for as high as
99.99 percent conversion efficiency.
oc For higher efficiency, the company
has been developing technologies such as
Outotec® LUREC™ strong gas processing
technology and Outotec® HEROS™
low pressure steam heat recovery. To
increase lifetime, Outotec has also worked
on equipment such as stainless steel
converters, CORD™ gas heat exchangers
and SX™ solutions. Our goal is to make
sure that we are always ready to respond to
changing requirements.
noraM e
Cscs NORAM has also brought several
new technologies to market over the last
two decades. One of these products is the
NORAM HP™ (High Performance) low
pressure drop ceramic saddles packing.
By choosing NORAM HP™ packing,
clients can debottleneck their acid plant
and increase production rate or reduce
energy consumption. HP™ packing has
been proven to reduce pressure drop across
the packing in acid towers and increase gas
flow throughput in the tower by 25 percent.
NORAM has also developed the Split
Flow™ radial flow gas heat exchanger to
address problems of corrosion in cold gas
exchangers due to condensation of the gas
at cold zones of the exchanger, typically at
the bottom tube sheet. For more than 15
years this patented product has improved
the reliability and life-cycle of cold gas
heat exchangers, SO3 coolers, pre-heaters
and tail-gas re-heat exchangers.
NORAM’s pipe-type acid distributors
have also been well received by the
industry because of their low cost and easy
installation. These distributors promote
uniform acid distribution into the packing
as no leveling is required, unlike that of
competitor products. Additionally, the
design features external access ports, which
provide added safety to service personnel.
Cmcs Although Chemetics was the first
to introduce silicon stainless steels
(SARAMET® alloy) to the industry in1982, the 1990s and early 2000s were a
period of acceptance by industry for this
alloy in all strong acid systems—towers,
tanks, distributors and piping—over
traditional brick lined vessels and cast iron.
Chemetics improved its mechanical designs
and modernized its fabrication facilities
to meet the increasing competition from
global sourcing. We have led in the supply
of modular gas exchangers and stainless
steel converters to lower the overall costand risk for overseas projects. As the acid
plants have been getting bigger, we have
continued to lead in the development of
acid coolers, pushing the limits of cooler
size, water and acid temperatures while
ensuring reliability.
ac Pp tcy In addition to completing severalmajor projects around the globe, including
the U.S., Australia, Morocco and Jordan,
Acid Piping Technology (APT) has
improved the options available to plants in
a number of ways.
Mondi™ piping alloy has undergone
major improvements in metallurgy and
casting techniques. Thanks to these
improvements, piping will now last the life
of the acid plant.
APT has partnered with ASC ValveCompany to provide excellent gas duct
valves and jug valves at competitive prices.
ASC is one of the few, perhaps only,
manufacturers offering tight shutoff, high
temperature, low pressure valves.
In recent years, APT has also
developed low pressure drop, high
efficiency tower saddle packing.
Kc K llC Koch Knight has challenged the
market by producing multiple product
advancements over the past 20 years with
the introduction of our PYROFLEX™
acid resistant sheet lining 500 for tower
membranes, FLEXERAMIC™ ceramic
structured packing for more efficient mass
transfer, LPD™ random packing for lower
pressure drop in towers and advancements
in our KNIGHT-WARE™ ceramic dome
supports to replace outdated support

W CMW’s process has incorporated
computer generated parts to be cut on
CNC equipment, which has increased the
accuracy and efficiency of vessel and duct
fabrication. Many developed parts that
once would have been cut long for shop
fit and trim can now be cut exactly with
great confidence and accuracy. Stitch cut
and pre-cut developed openings decrease
layout errors and speed the fit-up process.The computer-generated and CNC-cut
parts fit for a more uniform profile which
speeds welding and increases weld quality.
W Ms lws Pmps As a supplier, our focus is on
answering or anticipating the needs of the
industry. As a result, we have developed
several new pump sizes. The largest is the
18H pump, capable of delivering 11,000
gallons per minute against 128 feet of
head. Designed for both standard acid
applications and HRS facilities, this pump
quickly gained popularity among our
customers. We also developed our longest
pumps to date—at more than 40 feet—for
the concentrated solar power market. We
continue to adapt our existing products and
develop new products to meet the needs of
our customers around the world.

Since the first issue of Sulfuric Acid Today magazinerolled off the presses in November 1994, the vision ofthe magazine has remained the same: to publish a trade
journal for the sulfuric acid industry that commun icatesthe latest technology and services available in order tomaintain and operate acid plants more efficiently. We at Sulfuric Acid Today would like to sincerelythank al l of the following producing plant companies forallowing us to profile their company in our magazineand believing in our vision as well. In celebration of
our 20th anniversary, we took a look back at all of ourpast cover stories, as well as what those plants are doingtoday. We hope you enjoy these snapshots of our ever-changing industry.

Magma Metal Co. ofSan Manuel, Ariz., made itsmark on the industry as a rapid-fire turnaround facility. Withcomplete turnarounds taking
place at 15-month intervals,the company fine-tuned itsturnaround procedures to makethe necessary events both safeand efficient. At the time, Magmawas producing 1 million short
tons of 100-percent sulfuric acid per year, making it oneof the largest one-site producers of smelter acid in theUnited States.
Company Update
In 1995, The Broken Hill Proprietary CompanyLimited (BHP) acquired Magma Metals for $2.4 billion. Prior to its shutdown in 1999, Magma’s operat ionin San Manuel was the largest operating undergroundcopper mine in the countr y. In 2006, the Magma Metals plant was dismantledand sold. The two remaining smokestacks were toppled
in January 2007.
Kc u Cpp Cp.September 1995 – Vol. 1, No. 2
In June 1995, following
three years of planning andengineering, Kennecott UtahCopper Corp. brought theworld’s largest metallurgicalsulfuric acid plant online justoutside of Salt Lake City at
the Bingham Canyon Mine.This modern facility replaceda previously existing plant,which was shutdown in May
1995. The 3,860-ton per day plant was designed andconstructed by St. Louis-based Monsanto Enviro-Chem(now MECS Inc.).
In addition to its economic attributes, the new
facility also garnered attention as one of the most
environmentally sensitive plants in the world. The
MECS design included reductions of sulfur dioxide
emissions from around 17,000 tons per year to less than
1,000 tons per year.The facility was also the first to feature MECS’
new HRS system that helps capture and recover energy—
around 24 megawatts on a n average production basis. In
addition, it was the fi rst to use two HRS towers.
Company Update
In April 2013, a landslide occurred at the mine. It
was the largest non-volcanic landslide in the history
of North America. Around 65-70 million cubic meters
of dirt and rock thundered down the side of the pit.
Mining operations were shut down the previous day in
anticipation of the slide. The massive slide is expectedto cut the production of the mined copper by 110,000
short tons. A second slide caused an evacuation of 100
workers on September 11, 2013.
In addition to producing about 300,000 tons of
copper a year, the Bingham Canyon Mine also produces
approximately 400,000 ounces of gold; 4 million ounces
of silver; 30 million pounds of molybdenum; and 1
million tons of sulfur ic acid annually.

First started over a
century ago, the Asarco Inc. El
Paso, Texas, facility was one
of the nation’s oldest copper
smelters.
Originally built to
handle ore from Mexico, the
site consisted of two sulfuric
acid plants—a 1972 Lurgi
(575 tons per day) and a 1978
Monsanto (1,050 tons per day).
In the mid-1990s, theonset of stricter environmental standards prompted
Asarco to monitor the heat exchangers for potential
leaks that can increase emissions. In 1996, if a plant’s
sulfuric acid emissions exceeded 600 parts per million,
it was shut down. If a facility lost a heat exchanger due
to a few leaking tubes, the amount of tai l gas would shut
that site down. To determine a lea k, acoustic monitoring
equipment must be utilized inside the exchanger. But
accessing the exchanger requires a cool down process
that can ta ke days.
To save both time and money, Asarco called on VIPInternational (VIP) of Baton Rouge, La., and its high
temperature entry process. VIP’s high temperature entry
virtually eliminates the exchanger cooling process. VIP
can usually enter after only four hours of cooling.
Once inside, VIP uses acoustic emissions equipment
to spot the leaks, and can have them plugged long before
the conventional process would even begin.
Company Update
The Asarco El Paso, Texas, smelter was idled inFebruary 1999 due to hi storically low worldwide copperprices and the closure of several copper mines.
In its last full year of operation, the plant produced120,320 tons of copper. When the plant was fullyoperational, it provided about 400 high-paying jobs andhad a direct and indirect impact on the local economy ofabout $300 million an nually. Asarco was acquired by Grupo Mexico in November1999. With the purchase of Asarco, Grupo Mexicobecame the third largest copper producer in the world.Asarco is a subsidiary of Grupo Mexico Sa de CV. InApril 20 01, Asarco suspended operations i n East Helena,
Montana.In 2005, Asarco filed for Chapter 11 bankruptcy.
In 2009, Asarco emerged from bankruptcy and re-integrated into Grupo Mexico, deciding not to reopenits El Paso smelter. In December 2009 Asarco signedan agreement guiding the course of the environmentalcleanup of the El Paso 400-acre smelter, which willbe lead by the Texas Commission on EnvironmentalQuality. Cleanup of the site began in 2010 and the tworemaining smokestacks were demolished in April 2013.
Completion of the cleanup is targeted for 2015.

In the short span of
a decade, Potash Corp. of
Sasktachewan (PCS) hashelped change the future of
the fertilizer industry. Througha managerial philosophythat embraces growth and
change, PCS has built acompany of quality reserves,quality operations and quality
employees, which continues to be further enhanced bynew acquisitions.
In March 1997, PCS acquired Memphis, Tenn.-
based Arcadian Corp. T he company’s integration into the
PCS structure created a fertilizer empire unparalleledin quality and service capabilities. It cemented PCSas the No. 1 nitrogen producer in the U.S. and the
second worldwide, and enabled the company to buildconnections among subsidiaries and develop synergiesthat enable it to better serve its clientele as a one-stop-
shop. What was once a potash-only corporation is nowset for the 21st century as a powerhouse in the potash,phosphate and nitrogen fields.
At the helm of the PCS metamorphosis is Chairma n,President and Chief Executive Officer C. E. Chi lders. A40-year industry veteran, Childers joined PCS in 1987.
He brought with him a clear-cut vision of the industry’sfuture. He led the company through privatization in1989, bringing a return to shareholders of more than 500
percent.Childers’ foresight helped prepare the company for
the rising world population and the growing demands on
economies and farmers.

Throughout its 115-yearhistory as part of the coppermining industry, Phelps DodgeCorp. has evolved into oneof the world’s largest copperproducers, while never straying
from the belief that being agood business goes hand-in-hand with being a goodneighbor. Since its inception in
the 1830s, Phelps Dodge has placed environmentalresponsibility at the heart of its mining operations. Astimes, products and people have changed, those idealsset forth by the company founder, Anson Greene Phelps,have never faltered.
Phelps Dodge entered the copper mining businessin 1881. As part of the government’s requirements
placed upon copper miners and their sulfur emissionsregulations, Phelps Dodge operates three sulfuric acidplants for use with its copper smelting business. Theproduction of acid is essential to t he smelter operations.
In 1998, Phelps maintained two smelter operations – the Chino Mines Co. a nd Phelps Dodge Hidalgo I nc.The Hidalgo site runs two acid plants to keep up with itscopper smelting.
Phelps Dodge has found an alternative to the
transport and disposal of its sulfuric acid with thedevelopment of an internal consumer through its mine-for-leach operations. The leaching process requires theacid, so the two operations serve as a p erfect complement.
Company Update
In March 2007, Freeport-McMoRan Copper &Gold Inc. acquired Phelps Dodge corporation, creatingthe world’s largest publicly traded copper company.For a company update, see Freeport-McMoRan Spring/ Summer 2012—Vol. 18, No. 1 later in this article.

As one of the world’sleading manufacturers anddistributors of fertilizerproducts, CF Industries Inc. hascarved a unique niche for itselfas a consistent, unchangingface in a rapidly consolidatingindustry. The company’s
Florida Operations—whichinclude four sites at Bartow,Plant City, Hardee and the
Port of Tampa—serve as the base of all the company’sphosphate mining, manufacturing and distribution.
The four facilities within the Florida Operationshave been bolstered by CF’s unusual structure as acorporate entity owned by farm supply cooperativesthroughout the United States and Canada. The Floridasites work in tandem to mine, manufacture and distributethe necessary nutrients to CF’s cooperative owners. Thisco-op arrangement has been the saving grace for CF
during market ups and downs. With a built-in market,operating at capacity is always cost-effective. Production levels at CF are at an all-time high.Bartow produces between 1,000 and 1,100 tons per dayand Plant City generates as much as 7,000 tons per dayon average. In March 1999, Plant City levels reachedrecord-setting status with a 100-percent operating factoron all acid plants.
Company Update
CF Industries Florida Operations has always beena stellar example of production and safety for the
industry as a whole. In September 2003, the companywas recognized for its efforts and was named one ofAmerica’s Safest Companies by Occupational Hazards magazine. To earn that title, CF achieved over 6 millionsafe work hours at the Plant City Complex in late 2003. In 2005, CF Industries Inc. initiated an initial publicoffering as the final step to establishing CF IndustriesHoldings, Inc. as a public company.
Continuing their quest to become a nitrogenbellwether in the global fertilizer industry, in 2010 CFIndustries acquired Terra Industries Inc. Th is positionedCF Industries as the premier nitrogen and phosphate
fertilizer manufacturer in North America, the secondlargest nitrogen fertilizer producer in the world and thethird la rgest phosphate fertilizer producer among publiccompanies.

Dedicated to producinga cost-conscious product whileremaining a valiant defenderof the unique environmentin which it thrives, SFPhosphates Ltd. Co. hasproved a shrewd competitor
in the fertilizer industry. Thecompany’s operations consistof two facilities that work inconjunction with one another
to create a strea mlined, cost-effective system. The Vernal, Utah, site is home to the company’smining operations while the Rock Springs, Wyo.,location is home to the company’s fertilizer plant. Thetwo sites are connected with a 10-inch slurry line thattransports the phosphate concentrate over the UintahMountains to Rock Springs, some 96 miles away. Thepipeline, constructed by predecessor Chevron, has
freed the company from the reliance on other formsof transportation that are often affected by inclementweather in the region.
Two sulfuric acid plants power the Rock Springsoperation. The first, a Lurgi model, produces 1,900short tons per day. The more recent plant, brought onlinein 1995, is a 1,250 short tons per day Monsanto model.Prior to its installation, SF had been purchasing itssulfuric acid to supplement the plant’s production.
Two finished products are created at SF’s facilities—super phosphoric acid and MAP. Resources producedinternally, such as the sulfuric acid and the phosphate
rock mined at Vernal, help keep SF’s production costs toa minimum.
Company Update
In late 2003, the J.R. Simplot company purchasedFarmland’s interest in the SF Phosphates venture forapproximately $64.5 million. The manufacturingfacility at Rock Springs, Wyo., and the phosphate mineat Vernal, Utah, are now a Simplot-only enterpriseknown as Simplot Phospahtes. For an update on SimplotPhosphates, see J.R.

Rohm and Haas’ Deer Park site is a highly innovativespecialty chemicals business and a rising star in theLone Star State. World-class production facilities—bothin size and capacity—make the facility the crowning
glory in the company’s network
of franchises.Located in the shadow
of the towering 570-footmonument that marks thehistoric battle of San Jacinto,Rohm and Haas is a stalwartrepresentative of Texas’ 21stcentury leaders. A highlyinnovative specialty polymerand chemical company, Rohm
and Haas Texas is in constant growth mode as it buildsan ever-broadening technical base to serve the global
community.Founded in 1907 by two aspiring German
entrepreneurs, Rohm and Haas branched out to theUnited States in its first decade. In the 1920s, thecompany moved to specialty chemicals. Innovations inacrylic chemistry and the creation of Plexiglas helpedbolster company profits and reputation.
In the late 1940s, Deer Park set up shop along theHouston Ship Channel. Today, the site is one of the most
productive in the company’s network. Central to the siteis a sulfuric acid plant that produces more than half-a-million tons of sulfur ic acid each year.
Company Update
Consolidation has been a major factor in the sul furicacid industry over the past 20 years, and Rohm and Haasis no exception. In 2009, Dow Chemical Company boughtRohm and Haas for $15 million. Today, Dow Deer Parkoccupies 700 acres along the Houston Ship Channel, andemploys nearly 790 people within eight production areasthat operate as separate facilities or “plants within aplant.” The myriad of specialty chemicals manufacturedat the site include methyl methacrylate, acrylic acid,amines and various acrylates.

Mississippi PhosphatesCorp. is ideally located fordomestic and internationalbusiness along the coastalwaters of the Gulf of Mexico.The company has blossomedas a successful industrial
enterprise with a corporatephilosophy that is more aboutfamily and roots than bigbusiness and bottom lines.
In the mid-1950s, the company moved toward theGulf Coast area to combine all three primary plantnutrients—potassium, nitrogen and phosphate. Some40 years later, following a variety of acquisitions,mergers and overhauls, Mississippi Phosphates is nowa 250-person strong company, producing 900,000 tonsof DAP per year. The site has a 70,000-ton storagecapacity, and its close proximity to a port at Pascagoulaenables the company to ship at a rate of 8,000 tons ofproduct per day.
Presently, there are two Lurgi sulfur ic acid plants inoperation on the site. Both were original ly 1,500 tons perday plants. Upgrades and the addition of low-pressurecatalyst have pushed the plants to 1,750 tons per day.
Mississippi Phosphates combines its homegrownsulfuric acid with internationally imported Moroccanphosphate rock to create its quality product. Close
proximity to the southern Mississippi port and the high
quality of the imported rock made the decision an easyone. With the finely milled Moroccan rock, Mississippi
Phosphates only has to run one mill to prep the resourcefor production.
Company Update
In June 2003, Mississippi Chemicals voluntarilyfiled for a Chapter 11 reorganization. The companydetermined that this choice was the best for the long-
term interests of t he company and its stakeholders.In 2005, Terra Industries Inc. purchased the
nitrogen side of the business for $268 million, including
assumed debt. In 2010, Terra Industries was acquired byCF Industries for $4.7 billion. The combined companybecame the second largest nitrogen fertilizer producer in
the world. CF Industries and Terra have complementarystrengths in nitrogen, providing breadth and flexibilityin product offerings. In addition, the locations of CFIndustries’ and Terra’s facilities together expand thecombined company’s domestic reach. The phosphate side of the business emerged from
Chapter 11 proceedings as Mississippi Phosphates Corp.MPC’s manufacturing facilities at Pascagoula includethe two Lurgi sulfuric acid plants, a phosphoric acid
plant and a DAP granulation plant. The DAP granulat ionplant has a maximum annual production capacity ofapproximately 850,000 tons. The existing sulfuricacid plants have the capacity to produce sulfuric acid
sufficient for annual DAP production of approximately600,000 to 640,000 tons. The company has been plaguedin recent years by a string of safety violations, includingthe deaths of two workers.
In January, the company announced that it willadd monoammonium phosphate (MAP) to its product
line, beginning this spring. The addition of MAP tothe MPC product portfolio will allow the company
to take advantage of broader market opportunities. Inbroadening its product mix, MPC will combine internalmarketing efforts with an exclusive off-take agreementfor MAP with Interoceanic Corporation (IOC), ofOssining, N.Y., in an effort to enhance its targeting of
value-added market sectors.

With an eye on thefuture and a firm grasp on the
successes of the past, INEOSAcrylics has forged a securepost for itself as a globalleader in the acrylics trade.Though the INEOS name isrelatively new, the company’s
roots are deep—imbedded inthe strengths of its diversebackground, derived from the
combination of seven companies. The name INEOS was first adopted in 1999,following the purchase of ICI Acrylics by INEOSCapital and Charterhouse Development Capital. The
combination of the companies merged 70-plus years ofcutting-edge research and development history underone roof. Chemist John Crawford provided ICI with itsentrée into the worldwide methyl methacrylate (MMA)markets in 1931. Crawford built on the principals used to
polymerize MMA—first developed by Rohm and Haas—

and made the product a commercial success through its
applications in the aviation industry. Following World War II, INEOS was forced toseek new applications for MMA and PMMA. Today the
marketplace abounds with distinctive products includingappliances, paint, inks, adhesives, lubricants and textiles.
At each of INEOS’ five MMA plants, a sideprocess stream of weak acid is produced. The stream is
processed by burning the acid, reconstituting the freshacid and then reworking it back into the plant as oleum.That oleum is then utilized to create methacrylamide.
Each of INEOS’ five plants also houses a sulfuric acidregeneration (SAR) unit that together supply acid to
worldwide markets.
Company Update
In May 2002, INEOS Acrylics changed its name toLucite International to better align the company withits top brand: Lucite. In 2009, Lucite International was
acquired by Mitsubishi Rayon Co. Ltd., creating theworld’s largest supplier of MMA. Already a well-knownname throughout the Americas, Lucite has a growingpresence in Europe and other a reas of the world.
Over the past 15 years, Lucite International hasfocused on innovation. The company developed Alpha
technology, a new, patented route to MMA based onreadily available raw materials including ethylene,methanol and carbon monoxide. The first Alpha plant,a 120,000 metric tons per year facility in Singapore,became fully operational in 2007. Plans are in the works
for two more Alpha sites. Lucite International was also the first MMAproducer to successfully adopt a three-year overhaulcycle, which continues to release additional capacity
from existing assets. Lucite Internationa l’s focus on novel research intocatalysis and new processes has won the company
several awards, including the 2009 KirkpatrickChemical Engineering Award and the Chemical IndustryAssociation (CIA) 2009 Innovation Award.

From humble beginningsin the 1920s to its present
status as a major agribusiness,the J.R. Simplot Co. has beenan ever-changing reflection
of the times and technologiesthroughout its 80-plus yearsin business. Company founderJ.R. “Jack” Simplot recognized
the inevitability of change, andhe used that k nowledge to grow
his one-man operation to a major agribusiness, currentlyemploying over 9,000 people.
In the mid-1940s, Simplot’s livelihood was threatenedby the diminishing supply of phosphate fertilizer. Toensure a long-term supply for hi s agribusiness, Simplotfounded his flagship fertilizer production facility in
Pocatello, Idaho. Soon after the Don Plant went onlinein 1944, the Simplot name became synonymous with theprocessing of agricultural assistance products. The Don Plant is joined in its production of fertilizer
by two sites state side in central California. An additionalfacility is operated under the Simplot Canada Ltd. name,headquartered in Brandon, Manitoba.
The Simplot family of fertilizer producers expanded
once again in 1992 when Simplot and Farmland Industr ies
created a joint venture known as SF Phosphates Ltd. Co.Whenever the times have been hardest and the markets
have been their bleakest, Simplot Co. has relied upon the
wisdom of the company founder to guide it through. Byenacting a policy of low costs and high assets, Simplotturned his small farming entity into a global enterprise.
Company Update
The Simplot Company suffered a great loss withthe death of founder J.R. Simplot in May 2008. Thecompany has carried on, though, led by four members
of the Simplot family who comprise the executive
committee of the company’s board of directors. Theyhave continued his tradition of plowing profits back
into the enterprise, responsibly advancing J.R. Simplot’slifelong mission of bringing Earth’s resources to life.
From 2002-2005, Simplot paid several fines tothe EPA for unreported release of sulfur dioxide at the
Don Plant, among other things. Since then, though, thecompany has redoubled it’s efforts at environmentalstewardship.
Simplot is one of six major companies to join the
Obama Administration in an effort to significantlyreduce energy use over the next 10 years. The company
has received a number of awards, including the stateEarth Day award for environmental work completed
in Nevada, and a star award for outstanding safety andhealth results over the last 5 years. In June 2012, Simplot partnered with twoconservation groups in an effort to improve the water
quality of the Blackfoot River in Eastern Idaho. Theconsortium includes J.R. Simplot Company, Monsantoand Agrium/ Nu-West Industries, the Idaho Conservation
League and Trout Unlimited.
iMC PspsSpring/Summer 2002 – Vol. 8, No. 1 Feeding the world … itmay be a noble calling, but itis also a daunting task. But,
for the dedicated employees ofIMC Phosphates (now MosaicCo.), it’s all in a day’s work.
As the world’s leading
supplier of crop nutrients,IMC is at the forefront ofan industry that focuses
on supplementing the fooddemands of a growing planet. The focal point of IMC’s business is the phosphateprocess. Each year IMC generates 8.5 million short
tons of concentrated phosphates from approximately 4million short tons of phosphoric acid. This represents 10percent of the global capacity, making IMC a mainstayin global markets.
In central Florida, the company manages fourphosphate mines—Four Corners (the largest mine inthe world), Fort Green, Kingsford and Hopewell. Thecompany also operates two chemical process units—one
at New Wales and one at South Pierce. The New Walessite is the largest concentrated phosphate plant in theworld.
New Wales is a vast and complex facility. It is home
to five large sulfuric acid plants, three phosphoric acidplants and granular plants. On a typical day the sitebrings in around 20,000 tons of rock, 4,500 tons of
sulfur and 2,400 tons of ammonia. Railcars and trucks
leave the site daily with 13,000 tons of fertilizer and
2,500 tons of animal feed products.The Louisiana leg includes operations at Uncle Sam,
Faustina and Taft. Both Faustina and Taft were subject
to closures, the later permanently, during major industrydownturns.
Company Update
In 2004, Cargill joined forces with IMC to createMosaic Co. The new venture provided customersaround the globe with a more diversified product mix,including all three of the world’s primary concentrated
crop nutrients: phosphate, potash and nitrogen. For

In its 80-plus year
history, Newmont Mining Cor p.has been a stellar reflection ofthe company’s clearly stated
directive—creating value withevery ounce.
A global force in thegold industry, Newmont is the
world’s largest producer ofthe precious metal. Newmontoperations and assets dot the
planet and include five continents, 87 million ounces
of long-lived reserves and roughly 94,000 square milesof territory in the world’s best gold districts. Newmontcomplements its impressive catalog of resources withinvestments in technology, ensuring the greatest gold
recovery rates.Since the first discovery of the colossal Carlin Trend
in 1961, Newmont has maintained a strong presence inthe Nevada mining territory. The company’s current
operations include nine open pit mines, five undergroundmines and 15 processing facilities.
Remaining the leader in gold production requires
that Newmont rely on the latest technology for obtainingand refining its product. The company incorporates all ofthe advanced processes—leaches, oxide mills, flotationplants, autoclaves, roasters and bio-oxidation—to create
an impressive ore blend.As an offshoot to t he efficient extraction processes,
Newmont is left with an extensive waste stream of SO2.
As a conscientious member of the community and adedicated environmental steward, Newmont constructeda sulfuric acid plant at t he back end of Mill 6. This highlyeffective, profit-saving method for re-using Newmont’s
waste has also boosted the plant’s profit margin. Thecompany uses the sulfuric acid for cost-saving on site(as part of the cyanide detoxification process) and profitraising off site (as a supplier to other gold producers).
Company Update
Newmont’s mining operations in Nevada haveexpanded over the past 20 years. Operations now
include 14 open-pit and four underground mines and14 processing facilities. The properties operate as anintegrated unit, and together, they boast the widestvariety of processing methods of any gold mining
complex in the world. In 2013, Newmont expanded its scope of operationsat the Phoenix gold mine, near Battle Mountain. The
company began recovering copper from gold-mining

solution to dissolve the copper. Roughly one-third of theacid used is currently produced on-site. Production in
2013 was around 5 million pounds of copper, with anestimated annual production rate of 20 million poundsper year for the first five years of full-scale operation.
The company also has a long-standing dedication tosafety. The Carlin Surface Mine rescue team won the titleof 2013 Overall Champion at the National Mine Rescue
Championship, the first team from Nevada to do so.
