A mixture of 60 mol% propylene and 40 mol% propane at a flow rate of 1.0 kmol/h and at 25°C and 20 atm is to be separated with a polyvinyl trimethylsilane polymer membrane. The membrane skin is 0.1 μm thick and a pressure of 1 atm is maintained on the permeate side. Propylene permeability of the membrane material = 9 Barrer & Propane permeability of the membrane material = 2.8 Barrer Calculate the necessary membrane area (in m2) to achieve 30% stage cut. What are the mole fractions of propylene in the retentate and in the permeate?
