Question

t is desired to determine the membrane area needed to separate an air stream (Oxygen & Nitrogen). using a membrane 2.54 x 10-3 cm thick with an oxygen permeability of P'A= 500 x 10-10 cm3(STP)·cm/(s·cm2 ·cm Hg). The ideal separation factor is assumed to be 10. The feed rate is Mf = 1 x 106 cm3(STP)/s and the fraction cut is 0.20. The pressure selected for use are ph = 190 cm Hg and pl = 19 cm Hg. The feed composition of A is 0.209.

*Again, assuming the complete-mixing model, calculate the permeate composition, the reject composition, and the area.

*Estimate the permeate and retentate compositions if 80% of the feed permeates the membrane – explain your answer if it is different from (a).

(c) Estimate the permeate and retentate compositions if the O2/N2 selectivity = 30 instead of 10 (keeping everything else same as part (a)) – explain your answer if it is different from (a) 

 

The area is 2.39E8 cm^2. Make sure you get this area before posting an answer.
