A saturated-liquid mixture of 70 mol% benzene and 30 mol%toluene, whose relative volatility is 2.5, is to be distilled at 1 atm to produce a distillate of 80 mol% benzeneContinuous distillation followed by partial condensation. Thefeed is sent to the direct-heated still pot, from which the residue is continuously withdrawn. The vapors enter the top of a helicallycoiled partial condenser that discharges into a trap. The liquidis returned (refluxed) to the still, while the residual vapor iscondensed as a product containing 80 mol% benzene.

Question
A saturated-liquid mixture of 70 mol% benzene and 30 mol%toluene, whose relative volatility is 2.5, is to be distilled at 1 atm to produce a distillate of 80 mol% benzeneContinuous distillation followed by partial condensation. Thefeed is sent to the direct-heated still pot, from which the residue is continuously withdrawn. The vapors enter the top of a helicallycoiled partial condenser that discharges into a trap. The liquid
is returned (refluxed) to the still, while the residual vapor iscondensed as a product containing 80 mol% benzene. The molar ratio of reflux to product is 0.5.calculate andtabulate: (a) moles of distillate per 100 moles of feed, (b) moles of total vapor generated per mole of distillate, and (c) mol%benzene inthe residue. (d) For each part, construct a y–x diagram. On this, indicate
the compositions of the overhead product, the reflux, and thecomposition of the residue.
