摘要: FIELD: technological processes.SUBSTANCE: invention is related to membrane gas separation. Method for fractionation of low-molecular hydrocarbons mixtures characterised by the fact that crude mixture separation into permeate and retentate performed on a microporous with homogeneous porosity pore diameter in range 5-250 nm, at that, temperature as well side pressure kept below used provision capillary condensation components micropores membrane.EFFECT: higher efficiency process selectivity low molecular selective gases membranes cooling.8 cl, 1 tbl, 3 dwg
