Abstract
Carbon dioxide-containing feed stream such as flue gas is treated to produce a high-purity carbon dioxide stream by a series of steps including removing SOx and NOx with activated carbon, carrying out subambient-temperature processing to produce a product stream and a vent stream, and treating the vent stream by pressure swing adsorption or by physical or chemical absorption to produce a product stream which is recycled to the feed stream.
