Conceptual Process and Analysis of Water-Gas-Shift Membrane Reactor

A new conceptual water-gas-shift(WGS) process is designed for integrated gasification combined cycle(IGCC), using membrane reactor(MR) equipped with H2-permselective zeolite membranes for the WGS reaction.The new process makes it possible to capture CO2 before power generation process by converting CO in the syngas to CO2 which can be collected after WGS reaction. The new process also produces purer H2 for combustion in gas turbine. Conceptual design of the MR, mass and heat balance analysis, and cost estimation of the new process are also provided in this paper.
