Abstract
Carbon dioxide is recovered from a feed stream whose pressure is up to 30 psia by preferentially absorbing carbon dioxide from said feed stream into a liquid absorbent fluid, pressurizing and heating the resulting stream to a pressure sufficient to enable the stream to reach the top of the stripper at a pressure of 35 psia or greater, and stripping carbon dioxide from said stream in a stripper operating at a pressure of 35 psia or greater and recovering from said stripper a gaseous carbon dioxide product stream having a pressure of 35 psia or greater.
