Abstract
Impure carbon dioxide ('CO') comprising a first contaminant selected from the group consisting of oxygen ('O') and carbon monoxide (“CO”) is purified by separating expanded impure carbon dioxide liquid in a mass transfer separation column system. The impure carbon dioxide may be derived from, for example, flue gas from an oxyfuel combustion process or waste gas from a hydrogen (“H”) PSA system.
