  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 our Aspen PDF • Gasifier • Sulfur Removal • Water Gas Shift • CO2 Removal • Claus Process • Heat Loads • Optimization • Equipment Costs and Sizes • Individual Economics • Sensitivity Analysis • Location

  5. Agenda • PFD • Initial Control Scheme • Plant Layout (General Arrangement) • Calculations • Refined Economics • Report • Poster Preview????

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