    Abstract: A method of separating one or more first light components from a carbon dioxide containing gaseous mixture that contains at least 30 mole percent carbon dioxide. In accordance with the method, a feed stream composed of the carbon dioxide is cooled to effect at least in part, liquefaction of the carbon dioxide containing gaseous mixture. The feed stream and a stripping gas stream are introduced into a liquid-vapor contact column to initiate counter-current vapor liquid mass transfer and the formation of a gaseous column overhead stream and a liquid column bottoms stream. The stripping gas stream contains one or more second light components having boiling point lower than that of carbon dioxide and higher than that of the first light component(s) to enrich the gaseous column overhead stream with the first light component(s).

    Abstract: Method of purifying a feed stream containing carbon dioxide wherein the feed stream after having been compressed and dried is partly cooled and then used to reboil a stripping column. Thereafter, the feed stream is further cooled and expanded to a lower operational temperature of the stripping column. A carbon dioxide product stream composed of the liquid column bottoms of the stripping column is expanded at one or more pressures to generate refrigeration, then fully vaporized within the main heat exchanger and compressed by a compressor to produce a compressed carbon dioxide product. Refrigeration is recovered in the main heat exchanger from a column overhead stream extracted from the stripping column within the main heat exchanger either directly or indirectly by auxiliary processing in which carbon dioxide is further separated and optionally recycled back to the main compressor used in compressing the feed stream.
