ABSTRACT:
Carbon dioxide and water vapor are continuously removed by a venting membrane system which employs porous membranes and a liquid amine based sorbent, and which has a partial pressure gradient across the porous membranes. The partial pressure gradient induces absorption of carbon dioxide and water vapor from a gaseous stream, transport of the absorbed carbon dioxide through the pores of the membrane or to a second membrane, and desorption of the absorbed carbon dioxide.
