Keller, A P

A process is described for producing methanol from a feed gas comprising: passing at least a portion of the feed gas stream comprising hydrogen plus carbon monoxide and carbon dioxide to a first separation zone, the ratio of hydrogen to carbon monoxide and carbon dioxide in the feed gas stream being insufficient for effective methanol production; physically separating the feed gas stream in the first separation zone into a first hydrogen stream wherein the ratio of hydrogen to carbon monoxide and carbon dioxide is greater than in the feed gas stream and a first product stream comprising a hydrogen lean stream rich in carbon monoxide wherein the ratio of hydrogen to carbon monoxide and carbon dioxide is less than in the feed gas stream; passing the first hydrogen stream to a product reaction zone to form a mixed product comprising methanol formed by the reaction of the reactants comprisng hydrogen plus carbon monoxide and carbon dioxide and also residual components comprising residual hydrogen and carbon monoxide and carbon dioxide. The ratio of hydrogen to other reactants in the product reaction zone is such as to facilitate the formation of methanol; and removing the methanol and residual components as a mixed product stream from the product reaction zone.
