(Binary batch distillation)¹ Ten kmol of a feed having 65 mole% benzene and 35 mole% toluene is batch distilled at 1 atm pressure. Calculate the moles of distillate produced and the composition of the bottom product if distillation is done until (a) 75 mole% of the feed benzene leaves with the vapour; (b) the stillpot contains 35 mol% benzene; (c) 50 mole% of the feed is vaporized; (d) the accumulated distillate contains 75 mole% of benzene. Take a = 2.51.
