Presented at: Sixth Annual Conference on Carbon Capture and Sequestration, Pittsburgh PA, USA, 7-10 mei 2007.

This paper presents the results of system assessments that were conducted to compare conventional and advanced water-gas-shift reaction section in Integrated Gasification Combined Cycles (IGCC) with pre-combustion CO2 capture. The advanced shift reactor section comprises four staged reactors with distributed syngas and quench water addition in between the reactors. This advanced reactor section reduces the steam requirement of the shift reaction up to 70% at approximately 85% CO2 capture, in comparison with conventional shift reactor sections.
