Abstract

854,099. Cold separation of gas mixtures. CONCH INTERNATIONAL METHANE Ltd., [formerly CONSTOCK INTERNATIONAL METHANE Ltd.]. June 8, 1959 [June 23, 1958], No. 19587/59. Class 8(2). Separation of heavy hydrocarbons from liquefied natural gas containing mostly methane is effected in a column 16 after pressurizing the liquid feed in a pump 12, warming to near the boiling point in an exchanger 18 traversed by relatively warm product methane gas leaving the head of the column 16 and in a further exchanger 20 traversed by an external warm gas ; the column 16 having a reboiler 22 heated by an external medium, a duct 24 through which heavy hydrocarbon liquids are discharged, and a reflux feed duct 35 connected to the base of a chamber 34 in which any heavy hydrocarbons condensed in exchanger 18 are separated from the product methane gas which is discharged through a duct 36. Said product is expanded from about 535 p.s.i. to 100 p.s.i. in a turbine 44 after being warmed from - 120‹F. to 700‹F. in exchangers 38, 42 heated by external media and in an exchanger 40 heated by the expanded methane.
