| abstract | 1,247,533. Separating gas mixtures. FRIEDRICH UHDE G m.b.H. 9 Dec., 1968 [9 Dec., 1967], No. 58420/68. Heading B1L. [Also in Division C5] Gases containing hydrocarbons, e.g. natural gas, are purified of H 2 S by scrubbing the gases under pressure with an ester of phosphonic acid, and regenerating the scrubbing agent. In an illustrated embodiment, see Fig. 2 (not shown) dibutylester of n-butyl phosphonic acid is used to scrub a gas comprising 78 vol% CH 4 , and CO 2 and H 2 S under a pressure of 73 atmos. Charged scrubbing agent is led in turn through a partial and a final depressuriser, gas from the first, containing about 60 vol% CH 4 , being returned to the scrubber. The agent is then passed to a stripping column supplied with inert gas before being returned to the scrubbers. |
