Abstract (en)
[origin: WO2016020042A1] The invention relates to a method of cleaning a stream of matter (S), wherein the stream of matter (S) includes a C2+ fraction and at least one first gaseous substance and a different second gaseous substance, wherein the stream of matter (S) is subjected to a pressure swing adsorption (10) to remove the C2+ fraction. According to the invention, the stream of matter (S), after the removal of the C2+ fraction by means of a membrane (20), is separated into a retentate (R) and a permeate (P), wherein the first substance is enriched in the retentate (R) and the second substance is depleted in the retentate (R), and wherein the first substance is depleted in the permeate (P) and the second substance is enriched in the permeate (P).
