ABSTRACT:
Carbon dioxide is removed from a gas stream containing at least 250 ppm by volume of carbon dioxide by pressure swing adsorption in an alumina adsorption bed that is sized sufficiently large to remove at least 75 mole percent of the carbon dioxide in the gas stream. The process is particularly useful for removing substantially all of the carbon dioxide and water vapor from a stream of ambient air prior to separating the components of the air in a cryogenic air separation unit.
