US Patent:

50048627, Apr 2, 1991

Filed:

Jun 27, 1988

Appl. No.:

7/211745

Inventors:

Henry W. Hildinger - Chester NJ
Edwin D. Carlson - Sparta NJ

International Classification:

C07C 700

US Classification:

585867

Abstract:

This invention relates to a process of recycling condensate from a hydrocarbon or alcohol synthesis, wherein the condensate comprises water and contaminants such as lower molecular weight hydrocarbons, alcohols, and other oxygenates. A hot gaseous mixture comprising CH. sub. 4 and steam contacts the condensate so as to strip the contaminants from the condensate. The stripped contaminants, CH. sub. 4, and steam are separately recovered as a gaseous stream from the remaining purified water. The recovered CH. sub. 4 -containing gaseous stream may be used in synthesis gas (CO/H. sub. 2) generation processes with the generated synthesis gas then being used in a hydrocarbon synthesis process to produce heavy hydrocarbons.
