We prepared composite membrane which was made with polysulfone supported hollow fiber membrane coatedwith Hyflon AD to eliminate CO2 gas from mixed-gases which were generated in DME manufacturing processes. The performanceof module about simulated flaring gas was measured by using manufactured composite membrane. 1-stage evaluationresult shows CO2 concentration was below 3% at 1.2 MPa and at Stage cut 0.24 above. In addition CO2 removal rateand CH4 recovery rate was 80% respectively at the same condition. 2-stage evaluation result shows, when the CO2 concentrationof product gas was fixed at 5%, recycled CO2 at stage cut 0.074 had the same concentration as the feed gas and therecovery rate of CH4 was 99% at the moment.
