Membrane performance requirements for carbon dioxide capture using hydrogen-selective membranes in integrated gasification combined cycle (IGCC) power plants

The optimal point within the Robeson upper boundary

“…The obtained results do not differ widely from previous findings. Ku et al (2011) defined membrane performance targets for CO 2 capture using H 2 -selective membranes in integrated-gasification combined-cycle power plant systems. The authors concluded that at a 90% overall CO 2 capture rate, the required H 2 /CO 2 selectivity dropped from 60 to 20 as the H 2 recovery was reduced from 90% to 70%.…”

Parametric analysis and potential prediction of membrane processes for hydrogen production and pre-combustion CO 2 capture

“…To improve the economic advantages of the membrane system for CO 2 capture, a combination of adsorption or a cooling process within the membrane is proposed and is proved to provide an economic advantage for CO 2 capture over using the MEA adsorption process alone (Skorek-Osikowska et al, 2012). Furthermore, sweep gas is often used to enhance hydrogen recovery (Ku et al, 2011), which improves the driving force for H 2 recovery and reduces the hydrogen purity. This study primarily focuses on ultra-pure hydrogen acquisition as well as high product recovery.…”

Non-precious metal (pre-)commercial catalysts for Pd membrane water gas shift

“…Concerns about the climate impacts of the emissions of combined-cycle power plants have prompted interest in technologies for CO 2 capture and sequestration (CCS) [1]. Precombustion capture is a possible option to attain carbon capture before fuel combustion, by producing a hydrogen rich fuel and CO 2 stream for storage.…”
