Laboratory studies on the separation of CO2 and SO2 from gas mixtures by liquid membranes are reported. The membrane set-up consisted of an immobilized Polyethyleneglycol (PEG 400) membrane in series with another immobilized Diethanolamine (DEA)/PEG 400 membrane. SO2 was preferentially separated in the PEG 400 membrane while the DEA/PEG400 membrane separated CO2. Highest separation factors obtained for CO2 and SO2 were, 220 and 140, respectively.
