A carbon monoxide-hydrogen stream is to be separated using a polystyrene membrane 1mm thick. The permeability of hydrogen is PA=1.581010cm3(STP).cm/(s.cm2.cmHg) and carbon monoxide is PB=0.011010cm3 (STP).cm/(s.cm. cmHg). The concentration of hydrogen in the inlet stream is 0.27 and the flow rate is 23.1103cm3(STP)/s. The upstream pressure is set at 120cmHg and the downstream at 70cmHg. If the desired reject composition is 0.18, calculate to 4 decimal places, using the cross-flow model: a. the fraction of the feed permeated, [13 marks] b. the permeate composition, yp [4 marks] c. the area of the membrane required, Am.
