Propylene
Historically: • Produced in refineries or steam crackers as a secondary product
• Consume what is produced
• Consumption (non-fuel) governed by supply
Now: • Production is reducing but demand is growing fast
• In short supply relative to ethylene
• Development of new on-purpose production processes
• Production governed by demand
Propylene an unwanted product has become product in Demand

Propylene Production Routes
10
Traditional Co-product Sources of Propylene:
• Steam Cracking
• Fluidized Catalytic Cracking (“FCC”)
On-purpose Propylene Processes:
• Propane Dehydrogenation (“PDH”)
• Methanol to Olefins (“MTO”) and Methanol to Propylene
(“MTP”)
• Olefin Metathesis (“OTC”)
Steam Cracking • Currently most dominant production route for propylene in all regions
except North America
• Propylene is a by-product in ethylene production process of steam cracking
• Propylene yield varies with feedstock used for ethylene production
With increasing ethane feed in ethylene manufacture, propylene production from steam crackers has dropped
Feedstock Propylene Yield P/E (%) Ethane 1.9% 2.4
Propane 18.8% 36.2
Butane 17.0% 42.8
Naphtha 15.7% 47.0
Gas oil 14.7% 55.8

• Ongoing shale gas revolution continues to add to ethane supply in US – ethane surpluses projected despite new crackers and exports
• In January 2014, US feed slate exceeded 65% ethane
• The dramatic change in US feedstock supply in the last 6 years is structural
• This trend will continue in the coming years, mostly due to new crackers utilizing shale gas derived ethane
• Over 7 million tons of new ethylene capacity is expected before 2018, but producing relatively little co-product propylene (~200 kta)

Propylene from Refinery • A major source for propylene in North America but not in Asia or Europe
• FCC (fluidized cat cracker) and delayed coker produce propylene as a by-product
• FCC propylene yield is 8 to 9 %v (~4% wt.), but can go up to 20% v adding ZSM-5 to the catalyst or by severe cracking in FCC
• Propylene production often constrained by gas recovery units
• Delayed coker propylene yields are 2 to 3% (~1 to 2% wt.) depending on quality of crude
• Propylene from refineries contains around 30% propane requires separation
• Propane separation requires PP splitter, which is often a part of the petrochemical facilities
• Standalone PP splitters also exist (e.g., Enterprise splitter at Mont Belvieu)

US Propylene Production by Source
Propylene from steam crackers Propylene from Refineries
Propylene production has dropped in the US
US Now a Net Importer of Propylene
16
• US was net propylene exporter until refinery production started coming down after 2008
• Demand still growing
• Increased ethane use as feedstock has reduced production after 2009
• Hence US now an importer
• Trend may change after the new PDH plants come on stream

US Ethylene & Polymer Grade Propylene Price
Ethylene Poly-Grade Propylene
• Historically in US, ethylene prices higher than propylene
• Trend has reversed since 2007/2008
• Trend continues
Shrinking Supply of Traditional Propylene • Increased availability of shale gas in the US has increased
availability of ethane from NGLs
• This abundant ethane availability has resulted in increased usage of ethane for ethylene production
• Several large steam crackers based on ethane are under construction or are being planned
• P/E ratio of ethane-based steam cracker is substantially lower compared to other feedstocks, resulting lower propylene production
• Gasoline demand is shrinking because of more fuel-efficient engines and several other reasons
• Propylene production from traditional sources is dropping but propylene demand is increasing, mainly driven by increasing PP demand
Need for non-traditional supply source for propylene

Propane Dehydrogenation (PDH)
• Catalytic dehydrogenation of propane and propylene separation
• C2H6 --------> C2H4 + H2
• More than 4 mm tonnes propylene produced globally by this route
• Most significant on-purpose production route
• Technology Licensors: o UOP – Oleflex o Lummus – Catofin o Uhde / Krupp Thyssen – STAR
• UOP and Lummus dominate
• All new plants planned mainly in US or China
20
• Surge in PDH driven by US propane glut and shale gas ethane cracking created propylene shortage
• Surplus of shale gas derived liquids has driven down all NGLs prices
• US is now a significant net exporter of propane
• Limitations in export terminal capacity are stimulating new investment in export terminals
• US propane prices have fallen substantially below the discounted propane prices in Saudi Arabia for petrochemical use (Saudi domestic propane is priced relative to export naphtha)

MTO/MTP (Methanol to Olefins or Propylene)
• Methanol reaction in presence of zeolite type catalyst
• UOP process produces ethylene and propylene in fluidized bed reactors (MTO Process)
• Lurgi process also a similar catalytic process but with fixed bed reactors primarily for propylene production (MTP)
• Higher P/E ratio for MTP
• Both processes operational in China but not in other regions
• The technologies viable only if inexpensive methanol is available
• China utilizes its huge coal reserves to get methanol and reduces dependency on imported hydrocarbons

Plants marked in blue are MTP plants
Metathesis Route • Catalytic Reaction of n-butylene (C4 H8) and ethylene (C2H4) to
produce two molecules of propylene (C3H6) • Key determinants for this process are:
– Adequate price differential between ethylene/n-butylene and propylene
– Availability of surplus ethylene and n-butylenes at one location • Combined with a steam cracker (with liquid feed), this process
enhances the propylene/ethylene production ratio • Main licensor is Lummus (OCT), who can offer this technology
with or without their steam cracking process for ethylene • Lyondell Basell and BASF/Total operate metathesis plants in
the US • Borouge 2 (Abu Dhabi), SPCo in KSA operate metathesis units • Plants in Japan, Korea and other Asian countries also have
metathesis units 27
Conclusions
• Propylene historically long, now becoming short • Propylene from steam cracker and refineries still dominate • Steam cracker feedstocks moving toward ethane feed
which produces very little propylene • Refinery production of propylene is not increasing
because of reducing gasoline demand • On-purpose production of propylene becoming popular • PDH the largest source for on-purpose propylene • More popular in US with increasing propane availability • MTO and metathesis are gaining some ground but have
limitations
