    摘要: A gaseous product stream having a predetermined carbon dioxide content of 10-95 mol. % is produced from a gaseous feed stream containing 3-20 mol. % carbon dioxide by converting a portion of the feed stream to a purified stream containing 95-99.9 mol. % (dry basis) carbon dioxide and adding the purified stream to the remaining portion of the feed stream. Alternately, a portion of the purified stream is stored and added subsequently in response to fluctuating demand for the product stream.
