The Selexol Solvent process of Allied Chemical Corp. for treating both sour natural gases and coal- or oil-derived synthesis gases, uses strong solubility differences of various gaseous components in Selexol that acts as physical solvent. This permits a variety of uses in any gas purification service, including bulk removal of CO/sub 2/ alone or combined with water dew point control and recovery of C/sub 5/+ paraffins, as in the Lo-Vaca Gathering Co.'s Grey Ranch gas plant; removal of small amounts of H/sub 2/S (< 1 g/100 cu ft) together with CO/sub 2/, or for higher concentrations, by using a split cycle scheme with H/sub 2/S stripping, as in Northern Natural Gas Co.'s Oates, Tex., plant; the two-stage H/sub 2/S-CO/sub 2/ absorption required in SNG or synthesis gas generation from coal to minimize air pollution by H/sub 2/S, as in Bituminous Coal Research Inc.'s Bi-Gas pilot plant; and bulk removal of H/sub 2/S together with CO/sub 2/, mercaptans, and carbonyl sulfide in a single absorber, as in Norddeutsche Erdgasaufbereitungsges. m.b.H.'s NEAG II plant.
