► 1.5 kmol/h of air (79% N₂ and 21% O₂, by mole) at 10 bar and 20° C is separated using polyethylene oxygen selective membrane with 0.2 µm skin thickness to produce a permeate stream with 0.378 mole % 0₂. • Calculate the nitrogen and oxygen permeabilities and the O₂/N₂ selectivity Estimate the retentate flow rate and composition. Calculate the flux of N₂ and O₂ across the membrane assuming the permeate side is kept at 1 bar. Calculate the require membrane area? Diffusivity, cm²/s Solubility, kmol m Pa 0₂ 0.46 x 106 2.0 x 10¹⁹ N₂ 0.32 x 106 1.0 X10-⁹
