Among various CO2 capture technologies, membrane separation is considered as one of the promising solutions, because of its energy efficiency and operation simplicity. Many research and development are conducted for the (1) CO2/N2 (post-combustion: CO2 separation from flue gas), (2) CO2/CH4 (CO2 separation from natural gas), and (3) CO2/H2 (pre-combustion: CO2 separation from integrated gasification combined cycle (IGCC) processes). In this section, recent research and development of various types of membranes, such as polymeric membranes, inorganic membranes, ionic liquid membranes, facilitated transport membranes, and mixed matrix membranes, for these applications are reviewed, as well as future prospects of membrane separation technologies.

摘要

Among various CO2 capture technologies, membrane separation is considered as one of the promising solutions, because of its energy efficiency and operation simplicity. Many research and development are conducted for the (1) CO2/N2 (post-combustion: CO2 separation from flue gas), (2) CO2/CH4 (CO2 separation from natural gas), and (3) CO2/H2 (pre-combustion: CO2 separation from integrated gasification combined cycle (IGCC) processes). In this section, recent research and development of various types of membranes, such as polymeric membranes, inorganic membranes, ionic liquid membranes, facilitated transport membranes, and mixed matrix membranes, for these applications are reviewed, as well as future prospects of membrane separation technologies.
