3 3 Where is Celanese?

4 4 Strong leading business *Percentage of 2005 Celanese projected net sales and Celanese share of equity and cost investments. Sales by Segments* Chemicals 66% Ticona 16% Acetate 14% Performance 4%  Attractive hybrid business model  Leading global producer position  Clear advantage in technology and costs  Opportunities for savings and synergies Sales by Regions* North America 40% Europe 40% Asia 20%  2005 sales: $ 6.1 bn  2005 employees: ~9,300 Celanese Today

5 5 Strategic Growth Region Asia  Continue with joint ventures  Nanjing Complex  New GUR plant Building our presence in growth regions KEPCO, Polyplastics subsidiary, Taiwan. Korea Engineering Plastics Zhuhai and Kunming Fibers Co. Polyplastics Polyplastics, Malaysia Celanese Chemicals, Singapore Nantong Cellulose Fibers Co. Nanjing Acetyl Complex, China Tomorro w 33% of Sales in Asia

6 6 Performance Products Markets Acetyls Basic Chemicals Performance Vision for continued future growth Building Blocks Cash Drivers Celanese Acetate Nutrinova Adhesives, Paints, Coatings, Paper Automotive, E+E, Medical Devices Celanese Emulsions, Polyvinyl Alcohol Ticona Technical Polymers

7 7 Synthesis Gas Carbon Monoxide MethanolFormaldehyde Polymers Butyraldehyde Propion- aldehyde Butanol Propanol Acetic Acid Vinyl Acetate Acetic Anhydride PVOHEmulsions Heptanal Nonanal Perlargonic Acid Heptanoic Acid PE, BG, and TMP Butyl AcetatePropyl Acetate Synthesis Gas in Celanese

8 8 Paths to Synthesis Gas  Steam Reforming  Methanol  H 2 supply for Alcohols  Partial Oxidation  CO supply for Acetic Acid  Syngas supply for Aldehyde  Coal Gasification  CO supply for Acetic Acid

9 9 Syngas from Steam Reforming  CO 2 fed to drive water gas shift reaction towards CO  Nickel catalyst  Desulphurization of Methane Feedstock  Endothermic – heat supplied by burning Methane  Higher cost source of syngas for Celanese  Primarily used for production of Methanol

10 1010 Syngas from Steam Reforming  Conversion dependent on steam:carbon ratio, temperature, and pressure  Typical furnace is box-like, numerous catalyst filled tubes  Reformer Temperature – ~1450 F  Reformer Pressure - ~130 psig  Amine used to remove acid gases (primarily CO 2 ) CH 4 Steam CO 2 Fuel Gas Air Reformer Quench Pot Syngas CO 2 Gas Purification (amine) AbsorberStripper

11 1 Syngas from Partial Oxidation  No catalyst  Reacted at high temperatures under conditions of insufficient O 2  Exothermic – steam generated from heat  CO2 can be fed to drive water gas shift reaction towards CO  Primary source of syngas for Celanese  Used for raw material feed to Acetic Acid and Oxo Units (Water Gas Shift Reaction)

12 1212 Syngas from Partial Oxidation  Oxygen/CH 4 ratio is important to prevent high temperature or soot conditions  Reactor Temperature – ~2500 F  Reformer Pressure – 800+ psig  Amine used to remove acid gases (primarily carbon monoxide)  Membranes or coldbox is used to modify CO/H2 composition CH 4 O 2 Reactor Scrubber Syngas CO 2 Gas Purification (amine) Absorber Stripper WHB Syngas Membrane 1:1 CO:H 2 H2 Syngas 99% CO H2 Coldbox

13 1313 Syngas from Coal Gasification  No catalyst  Exothermic  Reaction adjusted through WGS to increase H2  Future source of syngas for Celanese in China

14 1414 Coal Gasification Coal Storage/ Grinding/Slurry Prep Gasification (2 100% Trains) Slag and Fines Handling Gas Cooling Acid Gas Removal Sulfur Recovery (2 100% Trains) Cold Box Ash Sulfur CO to Acetic Acid Unit H2 Sales Steam OxygenCoal by Railcar Syngas  Reactor temperatures can operate between 1650 and 2750 F  Similar purification steps to remove CO2 and adjust H2 composition  Additional process steps required to handle ash and sulfur  Additional steps required for handling solid raw material

15 1515 Synthesis Gas Carbon Monoxide MethanolFormaldehyde Polymers Butyraldehyde Propion- aldehyde Butanol Propanol Acetic Acid Vinyl Acetate Acetic Anhydride PVOHEmulsions Heptanal Nonanal Perlargonic Acid Heptanoic Acid PE, BG, and TMP Butyl AcetatePropyl Acetate Synthesis Gas in Celanese

16 1616 Reliability Sensitivity  What happens if syngas on-stream reliability (OSR) is poor?  Hypothetical Example: Unit producing 2,000 mT/day of acetic acid. Revenue of $100/mT. What is revenue benefit of 98.5% OSR versus 95% OSR?
