It is desired to separate a nitrogen-hydrogen mixture using a Permasep membrane 1mm thick. The permeability of hydrogen is P'A = 1.65x10cm (STP).cm/ (s.cm .cmHg) and nitrogen is P', = 0.031x10 10cm (STP).cm/ (s.cm?.cmHg). The feed composition is 0.35 mole fraction of hydrogen and feed rate is L=0.5x10 cm (STP)/s and the fraction cut 0=0.15. The pressures selected for use are ph = 150cmHg and D = 80cmHg. Assuming the arrangement is cross flow, calculate the permeate composition, the reject composition and the area of the membrane required to achieve this separation
