Patent
·
OSTI ID:6623334
An improved process is described for separating carbon dioxide from a fluid mixture with hydrocarbons comprising the steps of: (a) contacting a liquid-hydrocarbon tolerant membrane selectively permeable to carbon dioxide with a fluid mixture comprising carbon dioxide and at least one C/sub 3/ to C/sub 8/ hydrocarbon; (b) permeating carbon dioxide from the fluid mixture through the membrane at conditions which result in the presence of at least one condensed liquid hydrocarbon in the fluid mixture in contact with the membrane; and (c) separating the condensed liquid hydrocarbon from the gases which do not permeate the membrane.
