An immobilized liquid membrane was developed which at 100C has an SO2 flux of 0.0032 cc/(sec-sq cm-cm Hg) and an SO2/CO2 separation factor of 14. The membrane operated for one month at 100C with no change in permeation properties. The membrane could not withstand a pressure difference of 1 atm across it. However, a technique was recently developed which may make it possible to overcome this limitation. The low SO2/CO2 separation factor makes the use of this membrane for removing SO2 from power plant stack gases economically unattractive. An economically attractive system was conceived for treatment of higher SO2 concentration, and lower total flow stack gases, such as those emitted from many ore-smelting processes. (Author)
