Propylene: “The other olefin”
• Worldwide production in excess of 65 million tons per year
• Worldwide production valued in excess of $25 billion per year
• Demand growth expected will exceed 4.5 - 5.0% per year in the next five years
• Demand in Asia will be even stronger, growing at nearly 6% per year

APIC 2005APIC 2005
Often considered a byproduct
• About 61% produced in “ethylene” plants• About 34% produced in petroleum refineries• Only than 3% produced by on-purpose
propylene-only production plants

APIC 2005APIC 2005What Is Driving Propylene’s
Increasing Value?
• Strong demand for propylene derivatives is one of the keys– Polypropylene– Acrylonitrile– Oxo chemicals– Propylene oxide– Cumene– Isopropyl alcohol– Polygas chemicals.
8
APIC 2005APIC 2005Polypropylene Is Most Important
Derivative ….
• PP accounts for more than 60% of propylene demand due to its due to favorable properties in end use products– very low density– good mechanical properties– optical clarity– low moisture transmission
9
APIC 2005APIC 2005Making PP Competitive In Fast
Growing Applications ….• PP injection molded products
– Container caps and closures– Appliance parts– Disposable syringes– Household and miscellaneous products.
• PP fibers– Carpets – Non-woven market– Agricultural uses
• PP Films– Snack food packaging– Pressure-sensitive tape – Shrink-film overwrap– Electronic applications
10
APIC 2005APIC 2005Making Polypropylene The Fastest
Growing Thermoplastic
• Unlike other thermoplastics worldwide polypropylene consumption is expected to grow at nearly twice GDP growth rate.– About 6-7 percent in industrialized regions– More than 10 percent in China, Asia and Mideast
• Worldwide growth for polyethylene will average only about 4 percent over same period
11

Olefin Demand Comparison• Driven by high polypropylene and other propylene derivative
demand, propylene growth rate will exceed ethylene growth rate

APIC 2005APIC 2005Small Difference In Demand Has Large Impact on Supply Options
• Demand ratio is increasing with time• Production ratio is somewhat fixed by cracker

Increased Propylene Demand • Based on announced cracker projects olefin expansions will
fall short of increased propylene demand for next few years

New Capacity NeededAvailable From Crackers
15
APIC 2005APIC 2005Mideast Gas-Based Crackers
Produce Lower Propylene Yields
• Future additions of predominately gas based crackers in Middle East, motivated by low NGL prices will reduce worldwide average of propylene yield from steam cracking even further
16
APIC 2005APIC 2005Propylene Shortfall Will Have To
Be Meet From Other Sources
• Potential other sources of propylene– Refinery cat cracker recovery– Increase steam cracker severity– Increase use of heavier feeds for steam cracking– Metathesis (recent)– Propylene from methanol (new) – Propane dehydrogenation
17
APIC 2005APIC 2005
Refinery Cat Cracker Recovery
• Worldwide, propylene extracted from refinery catalytic crackers (FCC) units is the second largest source of propylene

APIC 2005APIC 2005
Refinery Supply Considerations
Actual percentage of propylene in the off-gases from any particular refinery depends on several variables– Type of refinery– Type of FCC reactor– FCC feedstock composition– Type of catalyst– Operating conditions– Gasoline production level– Crude oil processed– Propylene use in other fuel conversion processes (alkylation)
20
APIC 2005APIC 2005Asian Refinery Propylene Options
Are Limited
• Fewer gasoline-mode and high octane operations on Asia than in the United States
• Cat cracker propylene yields from distillate mode refineries is significantly lower
Typical Propylene YieldsDistillate mode 5%Gasoline mode 8%High octane mode 12%
21
APIC 2005APIC 2005
Increasing FCC Severity Can Help
• Gasoline mode FCC units can increase propylene yields by increasing severity
Typical Propylene YieldsLow severity (510 oC) 7%High severity (560 oC) 10%
22
APIC 2005APIC 2005
New FCC Catalysts and Processes
• New FCC catalysts now in development can be aimed at increased propylene production
• Modified FCC processes, known as “Deep Catalytic Cracking” or DCC combine catalyst and operating condition changes to raise propylene yields to as high as 16%
• Acceptance of such novel processes has been slow due to refiner’s reluctance to “experiment” with processes as centrally important as FCC
23
APIC 2005APIC 2005
Limits On Refinery Propylene
• Few new refineries• Few new FCC units growing at only 1%/yr • Refinery extraction limited by availability, not capacity• FCC catalyst additives and DCC will increase available
propylene • Most optimistic scenario suggests 3000 M tons of additional
propylene from refineries worldwide by 2014
24
APIC 2005APIC 2005Half of Announced Refinery
Propylene Projects Are In Asia
• Asian projects to upgrade refinery propylene will add 1.4 million tons of propylene by 2009
• Worldwide announced projects for entire world will add slightly less than 3 million tons of propylene in next five years
25
APIC 2005APIC 2005Un-Extracted Refinery Propylene Is Most Economical Refinery Choice
• Since increasing FCC severity reduces gasoline yield, most economically attractive incremental sources of refinery propylene are refineries with existing un-extracted propylene
• Significant investment in new FCC or DCC technologies is not anticipated
26
APIC 2005APIC 2005On-Purpose Production Will Be
Required Before 2009
• Either metathesis. propane dehydrogenation, or methanol based olefin olefins will be needed
• Metathesis has potentially lower, cost, but is less well proven technology
• Propane dehydrogenation requires a low cost source of propane and is important only in Middle East
27
APIC 2005APIC 2005500,000 Tons Of Metathesis
Expected - All in Asia
• Plans for 500,000 tons of new capacity for metathesis by 2009 could grow even higher as the technical certainties are demonstrated in recent new plants in Asia
28
APIC 2005APIC 2005900,000 Tons Of PDH Expected
- All in Mideaast
• Plans for 900,000 tons of new capacity for PDH by 2009, all of which is in Middle East and use propane feed at extremely low cost.
29
APIC 2005APIC 2005No MTO/MTP plants planned
before 2009
• Although a great deal of interest has been shown in methanol based production of both ethylene and propylene, there are currently no firm plans to use this technology before 2009

Conclusions
• Propylene demand will remain strong• Imbalance between ethylene and propylene growth
rate creating a propylene supply gap• Asian gap is substantial and is causing very strong
propylene pricing• New propylene from crackers must be augmented by
refinery extraction and on-purpose production• Metathesis and MTO will help close the gap
