Syngas Production from Petroleum Coke Gasification


Project purpose
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

Co2 sequestration
CO2 Sequestration

  • CO2 in our syngas is absorbed on Selexol to be selectively removed

  • Delete only one CO2 slide.
