[Also in Division C5] H 2 S and CO 2 are removed from gaseous mixtures containing them by scrubbing the gas mixture with an alkyloxazolidone, preferably with 3,5-dimethyloxazolidone-2, 3-methyloxazolidone-2, or 3-isopropyloxazolidone-2. The absorption is suitably performed under such conditions as 5-100, preferably 15-50, atmospheres, at temperatures of 10-40‹C., desorption of the solution being achieved by contact with air. Gas mixtures which may be so treated include natural gas, synthesis gas, industrial gases, coke oven gas and water gas.</p> |
