  1. Team Hotel: Russell Cabral, Tomi Damo, Ryan Kosak, Vijeta Patel, Lipi Vahanwala Advisors: Bill Keesom – Jacobs Consultancy Jeffery Perl, PhD – UIC Dept. Of Chemical Engineering March 8, 2011 Syngas Production from Petroleum Coke Gasification

  2. Project Purpose • What we are doing? • Producing syngas from petcoke • Using entrained flow gasifier • Implementing a rigorous syngas cleaning • Why we are doing this? • Making syngas for acetic acid production • Chemical production team specs • CO to H2 molar ratio of 0.409 • CO2 and N2 mixed in http://coalgasificationnews.com/tag/petcoke-gasification/

  3. Overall Block Flow

  4. Recap • Discussed the Shell™ membrane gasifier • Discussed our syngas processes • Sulfur Removal • Claus Process • Water Gas Shift • Flow Sheets • Early Material and Energy Balances

  5. Questions Brought Up Last Time • What was the heat rate brought up in the gasifier comparisons? • Why use N2 as a transport gas and not CO2? • How are we absorbing CO2? • What is a better definition of the quench?

  6. Agenda • Recent changes • Using Selexol instead of MDEA • Using the Superclaus • Aspen Simulation • Heat Load Identification • Economics • Aspen Price Evaluator (ICARUS) • Equipment Sizing • Energy Balance • Location Update

  7. Flow Sheeting: Overall Process Gasification Sulfur Removal Claus Process Water Gas Shift CO2 Removal

  8. Flow Sheeting: Gasification

  9. Flow Sheeting: Sulfur Removal To WGS

  10. Flow Sheeting: WGS & CO2

  11. Flow Sheeting: Claus Process

  12. Flow Sheeting: Claus Cont.

  13. Heat Loads for Claus Plant

  14. Heat Sink Optimization • Stream Pre-heating • Lower Heater / Cooler Duties • Heat Duty and Heat Ex. Cost Tradeoff Cold Furnace Gas Acid Gas Cold Acid Gas Hot Cooler HX Furnace To Claus Catalysts Hot Furnace Gas
