Membrane Technology and Research, Inc. (MTR) is developing composite membranes with superior carbon capture performance using a novel transformational approach. Two membrane targets have been identified: (1) carbon dioxide (CO2) permeance of 4,000 gas permeation units (GPU) with mixed-gas CO2/nitrogen (N2) selectivity of 25, and (2) CO2 permeance of 3,000 GPU with mixed-gas selectivity of 50. The first type will be used in the CO2 removal step and the second type will be used in the CO2 sweep step, both of which are parts of MTR’s innovative post-combustion CO2 capture process.
