SECTION A Answer ALL questions in this section 1.) A membrane is to be used to separate a gaseous mixture of A and B whose feed flow rate is Le- 1 x 10 cm? (STP)s. The feed composition of A is xp = 0.40 mole fraction. The desired composition of the reject is Xo = 0.25. The membrane thickness t = 1.54 x 10% cm, the pressure on the feed side is pH 100 cm Hg and on the permeate side is p = 25 cm Hg. The permeabilities are P'A = 50 x 100 cm (STP).em/(s.cm .cm Hg) and P"= 5 x 10-cm(STP).cm/(s.cm .cm Hg) Assuming the complete mixing model, calculate (5 marks) i.) The permeate composition, Yp (5 marks) ii.) The fraction permeated, 0. (5 marks) iii.) The membrane area, Am- iv.) The minimum reject concentration when the feed concentration Xp=0.4. (5 marks) V.) If the feed composition is increased to Xp=0.6, what is the new minimum reject concentration?
