The Media and Process Technology Inc. (MPT) project objective has been to develop a dual-stage membrane-based process (DSMP) for pre-combustion carbon dioxide (CO2) capture in an Integrated Gasification Combined Cycle (IGCC) power plant. The process utilizes MPT hydrogen (H2)-selective carbon molecular sieve (CMS) membranes, in conjunction with conventional water gas shift (WGS) reactors, in the first stage for enhanced production and bulk recovery of H2. Following cold gas clean-up, a palladium alloy-based membrane is used in the second stage for efficient residual hydrogen recovery from the high-pressure CO2 gas stream just prior to sequestration.
