Vol 1 Chapter 14: Coke gasification: advanced technology for separation and capture of CO2 from gasifier process producing electrical power, steam and hydrogen

Martin Holysh, Suncor Energy Inc, Canada

Abstract: The CO2 Capture Project (CCP) was established by eight leading energy companies to develop novel technologies that significantly reduce the cost of capturing CO2 for long-term storage. A significant focus of the project was in the area of pre-combustion technologies for the removal and capture of carbon dioxide (CO2) prior to fuel combustion.

This advanced technology study builds on previous CCP work that developed a conceptual process and engineering design for an integrated gasification combined cycle (IGCC) plant using petroleum coke as the feedstock to produce electrical power, steam, and hydrogen. Conventional absorption technology using the physical solvent Selexol was utilized for CO2 removal and capture.

The subject of this study was the development of a conceptual process and engineering design of an IGCC plant using petroleum coke as the feedstock to produce electrical power, steam, and hydrogen utilizing Fluor’s CO2LDSepSM advanced technology for CO2 removal and capture.

The study concludes that CO2LDSepSM technology can reduce the cost of CO2 capture by 16% when compared to the use of conventional Selexol technology. Neither the Selexol nor CO2LDSepSM technologies result in increased NOx or SOx emissions as compared to a baseline case with no CO2 capture.
