Abstract
Described herein are membrane processes for separating COfrom flue gas. An exemplary process involves passing a fluid stream including the flue gas across a membrane permeable to COand HO, removing treated gas from a feed side of the membrane that has less COthan the flue gas, and removing permeate from a permeate side of the membrane comprising COand HO. Suitably, the permeate is removed at a sub-atmospheric vacuum pressure. The permeate is then cooled to remove at least some of the HO from the permeate and form a smaller volume of HO-depleted, COenriched permeate.
