d) A distillation column is fed 100 kmol/h of a mixture of 50 mol % benzene and 50 mol % toluene at 101.32 kPa abs pressure. The feed is liquid at the boiling point. The distillate is to contain 90 mol % benzene and the bottoms 10 mol % benzene. The reflux ratio is 4.52:1 and equilibrium data for benzene-toluene system at 101.32 kPa are given below, where x and y are mole fraction of benzene.
