Leading Manufacturer Occidental Chemical (OxyChem) is a leading manufacturer with

facilities in the United States, Canada and Latin America. Based

in Dallas, OxyChem is a wholly owned subsidiary of Occidental

Petroleum, one of the largest U.S. oil and gas companies, based on

2016 year-end market capitalization.

Five-Time Winner Five-time winner of the American Chemistry Council’s top

safety performance award, including the “Responsible Care®

Company of the Year” award in 2015, in recognition of OxyChem’s

outstanding achievements in environmental, health, safety and

security performance.

Market Leader In 2016, OxyChem’s market position was among the top

three in the U.S. for the principal products it manufactures

and markets.

Star Status Eighteen OxyChem facilities have achieved Star Status, identifying them

as among the safest work sites in the U.S. under the Occupational

Safety and Health Administration’s Voluntary Protection Program.

Essential Products OxyChem is the second-largest merchant marketer in the world

of chlorine and the largest merchant marketer of its co-product,

sodium hydroxide (caustic soda). Chlorine is an essential building

block in thousands of products that make our lives safer, healthier

and more convenient. It plays a vital role in keeping the world’s

water supplies safe by controlling harmful bacteria and viruses.

Ethylene Cracker OxyChem operates a 1.2 billion pound-per-year capacity ethylene

cracker at its plant in Ingleside, Texas, along with a pipeline and

storage facility in Markham, Texas. The cracker, a 50/50 joint

venture with Mexichem that was constructed on time and on budget,

began commercial operations in 2017. OxyChem will use the

ethylene to manufacture vinyl chloride monomer, which Mexichem

will use to produce polyvinyl chloride (PVC) and PVC piping systems.

OxyChem Workforce OxyChem’s workforce included approximately 4,000 employees and

contractors at its manufacturing plants in North America and Latin

America, at year-end 2016. OxyChem employees have worked for

the company an average of 14 years.

Purchasing Power OxyChem purchased more than $3.1 billion in goods and services

from U.S.-based vendors in 2016. Of that total, approximately $1.7

billion was spent with large and small businesses located in Texas,

and more than $678 million was purchased from Louisiana vendors.

World’s Largest OxyChem is the world’s largest producer of potassium hydroxide

(caustic potash), a principal component in fertilizers, batteries, soaps

and detergents, and specialty glasses.

No. 1 Producer OxyChem is the world’s largest producer of calcium chloride, a

specialty salt that can be used to improve driving and pedestrian

safety under icy conditions, control dust on unpaved roads, and

enhance the performance of products and processes that contribute

to the supply of energy, food and other essentials of life.

Sil icates OxyChem is the second-largest merchant marketer in the world of

sodium silicates, with manufacturing facilities in Dallas; Chicago;

Cincinnati; Mobile, Ala.; and Augusta, Ga. These facilities have a

total capacity to produce 600,000 tons of silicates annually.

900,000 Homes OxyChem’s cogeneration power facilities at the Ingleside and

Battleground plants in Texas and the Taft plant in Louisiana are

together capable of generating approximately 1,540 megawatts

of electricity — enough to power more than 900,000 homes in

Louisiana and Texas annually.

Oxy Vinyls, LP OxyChem’s affiliate Oxy Vinyls, LP (OxyVinyls) manufactures PVC

resins, vinyl chloride monomer (VCM) and its precursor, ethylene

dichloride (EDC). Based on data from industry trade publications,

OxyVinyls is the world’s largest VCM producer and the third-largest

PVC supplier in the United States.

Energy Eff iciency Awards OxyChem plants in Texas and Louisiana received 2016 American

Chemistry Council Responsible Care® Energy Efficiency Awards

for six energy-efficiency improvements. Combined, energy savings

resulting from these OxyChem projects equated to 387,000 MMBTU,

or 70,000 barrels of oil equivalent, which contributed to a reduction

of 24,000 tons of greenhouse gas emissions.

Safety and Environmental Awards OxyChem facilities in Ingleside, Texas; New Johnsonville, Tenn.;

Niagara Falls, N.Y.; Taft, La.; and Wichita, Kan., received Chlorine

Institute process safety awards in 2016. Seven OxyChem and

OxyVinyls plants received awards in 2016 from the Vinyl Institute for

excellence in worker safety and environmental protection.

Rail Safety OxyChem received awards in 2016 for the safe transportation of

material from Norfolk Southern Corp., Kansas City Southern Railway

and the Canadian National Railroad.

Milestone Anniversaries Two OxyChem plants celebrated milestones in 2016. The Taft plant

in St. Charles Parish, La., commemorated 50 years of operations,

and the Dallas Silicates Plant celebrated its 75th anniversary.

Waste Minimization, Reuse and Recycl ing Awards OxyChem plants in Geismar, La.; Wichita, Kan.; and Taft, La.;

received American Chemistry Council Responsible Care® Waste

Minimization, Reuse and Recycling Awards in 2016 for significant

achievements in promoting recycling and reuse activities.

Climate Friendly In 2016, OxyChem began constructing a plant at its Geismar, La.,

facility to manufacture a new, next-generation raw material for use

in the production of an advanced climate-friendly refrigerant.

ProductsChlorineOne of the most abundant naturally occurring chemical elements,

chlorine plays a role in more than 50 percent of all commercial

chemistry. It is an essential building block for safe drinking water,

waste water treatment, pharmaceuticals (including antibiotics,

pain relievers, cancer treatments), plastics, dyes, cosmetics,

construction materials, shatter-resistant glasses, bulletproof vests,

electronics, adhesives, automobile parts (including seat belts)

and sports equipment.

Sodium HydroxideCommonly known as caustic soda, sodium hydroxide is co-

produced with chlorine and has a wide variety of applications in

many industries, including pulp and paper, aluminum, soaps and

detergents, textiles, petrochemicals and chemical processing.

Caustic soda is also used in the production of bleach, food

processing, water treatment, battery recycling, pharmaceuticals,

drilling muds, petroleum refining and agricultural chemicals.

Potassium Hydroxide Potassium hydroxide, or caustic potash, is the largest-volume

potassium chemical for non-fertilizer use. The largest users of

caustic potash are the soap and detergent, fertilizer, and chemical

industries. Other uses for caustic potash are molten salts, dyes,

pharmaceuticals, photographic chemicals and batteries.

Calcium Chloride Calcium chloride is largely used to control snow and ice on

sidewalks, parking lots and roads; to suppress dust on unpaved

surfaces; and for road stabilization. Its use has been extended

through a variety of innovative applications in oil field operations,

industrial processing, agriculture, water treatment, refrigeration

systems and tire weighting.

Sodium Si l icatesSodium silicates are aqueous liquids containing sodium oxide (Na2O)

and silicon dioxide (SiO2 ) in various ratios. Sodium silicates serve

a wide range of end-use markets, including thermal and acoustical

insulation, ceramics, soaps and detergents, paper products, paint

and pigments, and water treatment.

Vinyl Chloride MonomerVinyl chloride monomer (VCM) is the key chemical precursor to

polyvinyl chloride (PVC). It is produced commercially by combining

a hydrocarbon feedstock, namely ethylene, obtained by cracking

natural gas or petroleum, with elemental chlorine.

Polyvinyl Chloride OxyVinyls offers a full product line of polyvinyl chloride (PVC)

resins suitable for most vinyl production applications. PVC is

widely used in medical applications, piping systems, siding,

irrigation and sewer systems, electrical conduits, window frames,

water distribution systems, wire and cable insulation, flooring and

wallcoverings, fencing, gutters and downspouts, landfill liners and

fire-sprinkler piping.

ACL® Chlorinated Isocyanurates Chlorinated isocyanurates are leading dry sanitizers used for

residential swimming pools and spas, effectively eliminating germs

and algae. Their disinfection properties make them an important

component of dishwashing detergents and industrial water treatment

products. OxyChem’s chlorinated isocyanurates are also approved

for routine potable water chlorination.
