A saturated-liquid mixture of 50 mol% benzene and toluene is distilled at 101 kPa in an apparatus consisting of a still pot, one theoretical plate, and a total condenser. The still pot is equivalent to an equilibrium stage. The apparatus is to produce a distillate of 75 mol % benzene.Calculate,the moles of distillate per 100 moles of feed. Assume an α of 2.5 (a) No reflux with feed to the still pot. (b) Feed to the still pot with reflux ratio =3. (c) Feed to the plate with a reflux ratio of 3. (d) Feed to the plate with a reflux ratio of 3 from a partial condenser. (e) Part (b) using minimum reflux. (f) Part (b) using total reflux.
