A mixture of 60 mol% propylene and 40 mol% propane at a flow rate of 100 lbmol/h

Question:

A mixture of 60 mol% propylene and 40 mol% propane at a flow rate of 100 lbmol/h and at 25°C and 300 psia is to be separated with a polyvinyltrimethylsilane polymer (see Table 14.10 for permeabilities). The membrane skin is 0.1 mm thick, and spiral-wound modules are used with a pressure of 15 psia on the permeate side. Calculate the material balance and membrane area in mas a function of the cut (fraction of feed permeated) for: 

(a) Perfect-mixing flow pattern and 

(b) Crossflow pattern.
