  • Process for separating CO.sub.2 from other gases
    Patent number: 4659343
    Abstract: An improved process is described for separating carbon dioxide from light hydrocarbons by means of a membrane. The membrane separation is operated so that hydrocarbon liquids are condensed in contact with the membrane. This process is particularly valuable for the separation of gas mixtures into separate acid gas, gaseous hydrocarbon and liquid hydrocarbon streams.
