A method of separating one or more light components, such as helium, from a carbon dioxide containing stream. A two-phase stream is obtained, at least in part, by cooling a pressurized feed stream to at least partially condense such stream. The stream that is subsequently degassed to produce a first vapor stream enriched in the light component(s) and a first liquid stream containing an entrained fraction of the light component(s). The first liquid stream is expanded to create another two-phase stream that is degasified to produce a second vapor stream that is also enriched in the light component(s) and a second liquid stream having an enriched carbon dioxide content. The second liquid stream is repressurized and vaporized. In case of a supercritical feed, the pressurized feed stream is expanded after having been cooled. Thereafter, the feed is degassed to produce the light component enriched vapor stream and a liquid stream enriched in the carbon dioxide. The resultant vapor streams, enriched in the light component(s) may then be further processed to isolate the light components.
