Abstract
1307640 Cold separation of gas mixtures MESSER GRIESHEIM GmbH 30 July 1970 [1 Aug 1969] 36964/70 Heading F4P Partial liquefaction of a compressed gas stream, e.g. natural gas prior to separation in a rectification column 11 is effected by passage through heat exchangers 4, 5, 6, 10, 15 which are themselves cooled by a reverse flow of evaporating high and low boiling point refrigerant components, e.g. C 2 to C 4 hydrocarbons and methane having been separated at 27 from the refrigerant mixture delivered by a compressor 24; the so-warmed separated refrigerant components then being returned to the compressor. The feed natural gas having been cooled in exchanger 6 is freed of condensed heavy hydrocarbons at 7 and after further cooling at 10 is separated at 12 into crude gaseous nitrogen and crude liquid methane which are further cooled in reboilers 16, 17 and expanded 20, 18 into the column 11 from which product liquid methane is drawn at 22 whilst effluent nitrogen is returned through exchangers 15, 10, 6, 5, 4.
