  1. Kees Hettinga Sabic Europe Walter Mirabella Lyondell Chemical Europe Com 2007(18) - Stakeholders meeting Brussels, Belgium 29th May 2007

  2. BioFuels Evaluated on CO2 • Fuel Quality Directive Review Proposal Requiring Accurate CO2 Evaluation of Fuels • EU MSs Targeting BioComponents CO2 Performance: • GERMANY (meo/IFEU) • NETHERLANDS (Cramer Committee) • UNITED KINGDOM (Low Carbon Vehicle Partnership)

  3. Why a new evaluation for EtOH/EtBE? • ETBE Currently Key to EU ETOH Blending • Address CO2 Impact Triggered by Refinery Optimisation after Adding EtOH and/or EtBE • Focus on Comparing the two Ethanol “forms” within the refinery • Addressing “middle-man” Misconception: • “Extra processing step costs energy, therefore CO2 emissions expected to be larger with ETBE than for ethanol direct blending” • Demonstrate Reality: • ETBE allows lower Carbon intensive blend stock, saving CO2

  4. “Bio-Petrol”:Etherification Central in the Supply Chain Ethanol (Distillation) ETBE (Etherification) Refinery (Formulation) Distribution (Consumption) Bio-Mass (Agriculture)

  5. “Forms” of Ethanol: >3/4th of EU Bio-Ethanol Blended Today as ETBE

  6. CO2–Related Factors Affected by Refining • Gasoline composition • H/C ratio (Aromatics, olefins, lights) • Processing fuel consumption • Octane-production/energy-use correlation • Indirect effects • Changed refinery output due to other optimization

  7. Octane/Refinery Fuel Use Correlation: Long Known Factor Source: CONCAWE’s “RUFIT” report N° 6/78 (dec 1978)

  8. Study Basis • Refinery modeling performed by consultant • Main refinery products constant on energy basis • Time base-line 2010 • Base petrol summer grade with no bio-components • Compare ethanol directly blended vs. ETBE • Ethanol is “smart” blended

  9. Different ETOH Blending Options

  10. Theoretical ETOH CO2 Performance Basis CH3-CH2-OH + 3O2 = 2CO2 + 3H2O 46.07 44 5500 10506 50% 5253

  11. CO2 Scenarios Comparison:Detailed Relative Contribution A = Ethanol 5%v/v & MTBE export, B = Ethanol 5%v/v & MTBE to iC8=, C = Existing MTBE converted to ETBE + ETOH-DB to %5v/v D = Existing MTBE + Available iC4 converted to ETBE + ethanol to 5%v/v E = As above + Incl nC4= isomerisation then to ETBE

  12. CO2 Scenarios Comparison:Overall Relative Contribution A = Ethanol 5%v/v & MTBE export, B = Ethanol 5%v/v & MTBE to iC8=, C = Existing MTBE converted to ETBE + ETOH-DB to %5v/v D = Existing MTBE + Available iC4 converted to ETBE + ethanol to 5%v/v E = As above + Incl nC4= isomerisation then to ETBE

  13. CO2 Scenarios Comparison:Refinery Impact in Perspective with Hypothetical Overall Saving A = Ethanol 5%v/v & MTBE export, B = Ethanol 5%v/v & MTBE to iC8=, C = Existing MTBE converted to ETBE + ETOH-DB to %5v/v D = Existing MTBE + Available iC4 converted to ETBE + ethanol to 5%v/v E = As above + Incl nC4= isomerisation then to ETBE

  14. CO2 Scenarios Comparison:Net Refinery Impact in Perspective with Hypothetical Overall Saving A = Ethanol 5%v/v & MTBE export, B = Ethanol 5%v/v & MTBE to iC8=, C = Existing MTBE converted to ETBE + ETOH-DB to %5v/v D = Existing MTBE + Available iC4 converted to ETBE + ethanol to 5%v/v E = As above + Incl nC4= isomerisation then to ETBE

  15. Economics Drive the Choice Between ScenariosUnwise Regulations Backfiring on CO2 SCENARIOS CHOICE CO2 IMPACT REGULATIONS ECONOMICS FQDR BFDR ETS ….

  16. Conclusions • CO2 Evaluation Key in the EU Bio-Fuels Agenda • Impact within Refinery Significant • ETS doesn’t Cover all CO2 Savings from Refinery • Bio-ethers Greatly Enhance Ethanol CO2 Performance • Etherification Beyond Current Capacity Good for CO2 • Regulations Penalising ETBE Counterproductive for CO2
