The New Jersey Institute of Technology (NJIT) is developing, via laboratory-scale experiments, a pressure swing membrane absorption-based (PSMAB) device using a non-dispersive, membrane-based gas-liquid contactor that produces hydrogen at high pressure for integrated gasification combined cycle (IGCC), as well as a carbon dioxide (CO2) stream, between 1 and 5 atm, that contains at least 90 percent of the CO2 from a feed gas at ≈200 °C and 300 pounds per square inch gauge (psig).
