A contained liquid membrane process is studied for simultaneous removal and possible recovery of SO/sub 2/ and NO/sub chi/ from flue gas. The low concentration range (500-5000 ppm SO/sub 2/, 500 ppm NO) necessitates the use of high-selectivity membranes. As part of an ongoing investigation, the authors are separately studying the permeabilities and selectivities for a gas mixture of SO/sub 2/, CO/sub 2/, N/sub 2/, H/sub 2/O, and a gas mixture of NO/sub chi/, CO/sub 2/, N/sub 2/, O/sub 2/, H/sub 2/O. The species permeabilities and the selectivity values are reported for a number of liquid membranes. The more effective of these liquid membranes are being used in hollow-fiber contained liquid membrane permeators. Separation results are reported for a feed gas mixtures of SO/sub 2/, CO/sub 2/, N/sub 2/, O/sub 2/, and H/sub 2/O.
