A membrane is to be used to separate a gaseous mixture of A and B whose feed
flowrate is Lintimes cm
STP s and the feed mole fraction is xin The desired
outlet composition of the retentate is xout The membrane thickness, z is times
cm and the permeability coefficients for A and B are Barrer and Barrer,
respectively. The upstream pressure is cm Hg and the downstream pressure is cm
Hg Treat cmSTP as if it were moles in other words, do not convert it to moles.
a What is the average permeate composition, yout?
b What is the stage cut, VoutLin
c Estimate the membrane area, A
