Abstract
1291745 Cold separation of gas mixtures FLUOR CORP 21 Oct 1970 [7 Nov 1969] 50062/70 Heading F4P Methane is separated from a mixture thereof with ethylene and higher hydrocarbons by feeding a cold feed stream 1, 2, 15, to a methane separation column 22, withdrawing at 28 methane-rich vapour therefrom and after further rectification at 29 and withdrawal at 33 a portion 29 of this vapour is expanded in a turbine 35 which drives a compressor 36 for compressing a further portion 39 of the methane vapour and this compressed methane is cooled at 30, 46 to condensation temperature, separated at 45 and the condensate is returned through a line 49 to column 29 as reflux; product methane being the exhaust of turbine 35 to which is added liquid methane withdrawn at 51 from column 29 and product ethylene and higher hydrocarbon being withdrawn at 53 from the base of column 22.
