Abstract
A gas separation process for treating flue gases from combustion processes, and combustion processes including such gas separation. The invention involves flowing the flue gas stream to be treated across the feed side of a membrane, flowing a sweep gas stream, usually air, across the permeate side, then passing the permeate/sweep gas to the combustor.
