PATENTS 3912. ------. [WHITE, P. C.] (Standard Oil Co. of Indiana). Separation of Hydrocarbon-Synthesis Products. United States Patent 2,501,115, Mar. 21, 1950; appl. filed Oct. 30, 1945, Serial No. 625,552, 5 claims (Cl. 260-450). Chem. Abs., vol. 44, 1950, p. 5082. Gaseous effluents from the Fischer-Tropsch synthesis are cooled to 50°-250° F. 2 liquid phases form in the separator, aqueous and liquid hydrocarbons. The uncondensed stream of rich gas goes over to a 2-phase absorber. Organic oxygenated compounds are removed from the aqueous phase. A lean absorber-oil fraction is recovered from the liquid-hydrocarbon phase. The lean aqueous phase and the lean absorber-oil fraction are used with the gas phase. Organic oxygenated compounds are absorbed in the aqueous phase, and the normally gaseous hydrocarbons selectively absorbed in the oil fraction. 6 United States patents cited. |
