31. ------. [ARNOLD, G. B., AND HESS. H. V.] (The Texas Co.). Processes for Manufacturing Hydrocarbons and Alcohols. United States Patent 2,542,454, Feb. 20, 1951: appl. Filed Aug. 31, 1946. Serial No. 694,320: 3 claims (Cl. 260-450).

Product mixture from the Fischer-Tropsch synthesis is separated into gas, hydrocarbon, and H₂O phases at 175°-350° F. and a pressure sufficient to maintain liquid-phase conditions. The O-containing organic compounds are removed from the hydrocarbon phase containing organic compounds. The H₂O phase is subjected to a countercurrent contact with a portion of the oxygenate-free hydrocarbon fraction at 175°-350° F., 150-300 p. s. i. A hydrocarbon extract phase containing nonacidic oxygenate content. The raffinate is discharged and the hydrocarbon phases are combined. 1 literature ref, and 6 United States Patents cited.
