In the synthesis of methanol from carbon monoxide and hydrogen, the circulating gases are purified by being passed in rapid co-current flow with a liquid absorbent, which removes at each operation only a small proportion of the undesired constituents (nitrogen, methane, &c.). The absorbent is regenerated for further use and may be continuously circulated. The washer may consist of a pipe through which the liquid and gas are passed upwardly. Specification 331,916, [Class 32], is referred to.ALSO:In carrying out reactions with circulating gases the gases are purified by being passed in rapid co-current flow with a liquid absorbent, which removes in each operation only a small proportion of the undesired constituents.
