For an equimolar feed, cyclohexane and benzene products of 98 and 99 mol%, respectively, can be produced. Alternatively, the use of a three-stage pervaporation process, with selectivity for benzene using a polyethylene membrane, has received attention. Consider the second stage of this process, where the feed is 9,905 kg/h of 57.5 wt% B at 75oC. The retentate is 16.4 wt% benzene at 67.5oC and the permeate is 88.2 wt% benzene at 27.5oC. The total permeate mass flux is 1.43 kg/m2-h and selectivity for benzene is 8. Calculate flow rates of retentate and permeate in kg/h and membrane surface area in m2.

Question
For an equimolar feed, cyclohexane and benzene products of 98 and 99 mol%, respectively, can be produced. Alternatively, the use of a three-stage pervaporation process, with selectivity for benzene using a polyethylene membrane, has received attention. Consider the second stage of this process, where the feed is 9,905 kg/h of 57.5 wt% B at 75oC. The retentate is 16.4 wt% benzene at 67.5oC and the permeate is 88.2 wt% benzene at 27.5oC. The total permeate mass flux is 1.43 kg/m2-h and selectivity for benzene is 8. Calculate flow rates of retentate and permeate in kg/h and membrane surface area in m2.
