A method for removing H.sub.2 S and CO.sub.2 from a natural gas stream involves the employment of a dried cellulose ester membrane having a permeability for H.sub.2 S and CO.sub.2 of at least 10.sup.-8. A gas permeation process may also be used to produce a CO.sub.2 rich stream from gas in gas reservoirs which contain a large amount of CO.sub.2. The produced rich CO.sub.2 stream may then be used in flooding processes for enchanced oil recovery.
