1. A process for producing a carbon dioxide stream, the process comprising:
separating, in a first separation zone, a feed stream comprising carbon dioxide and one or more additional components comprising hydrogen, nitrogen, carbon monoxide, methane, oxygen, argon, or mixtures thereof into a carbon dioxide enriched stream and a carbon dioxide depleted stream enriched in said one or more additional components;
separating, in a second separation zone, the carbon dioxide depleted stream into a first stream comprising said one or more additional components and a second stream comprising at least 50% of the carbon dioxide in said carbon dioxide depleted stream;
increasing a pressure of the second stream to provide a high pressure second stream, wherein the pressure is increased using a compressor;
combining the high pressure second stream with the feed stream; and
separating the high pressure second stream in the first separation zone.
