Question 2: Products purity and feed flow rate in complete mixing model A binary mixture of gas A which has mole fraction of xy = 0.5 and gas B is being fed at a flow rate of q, into a membrane module in order to effect seperation of the two gases. The membrane process is to be operated with a feed-side pressure of P = 80 cm Hg and permeate-side pressure of p₁ = 20 cm Hg. Gas A has a permeability of P = 400 x 10-10 cm³ (STP) cm/(s cm² cm Hg), and the separation factor between gas A and B is a = 10. If the thickness of the membrane is t = 2 x 10 cm and the fraction of the feed that is permeated is 8 = 0.25, (a) Calculate the permeate composition. yp (b) Calculate the reject composition, xo (c) Calculate the feed flow rate, q, in cm³ (STP)/s if the available area of the membrane is 3 x 108 cm²
