Consider a separation train consisting of two distillation columns which are designed to separate a threecomponentmixture of benzene, toluene, and xylene into three streams, each rich in one of the species asshown below. For the first unit the feed rate is 1,000 mol/h containing 20 mol % benzene, 30 mol % toluene mixture, the bottoms product is of 2.5 mol % benzene, 35 mol% and all of the xylene fed to the unit. The overhead product of the second unit has 8 mol% benzene, 72 mol % toluene, and benzene in this stream is 100 % of benzene fed to this unit. Determine how much material will be processed by each unit and how this material will be divided among the outlet streams. ( All compositions labeled below are mol fractions.)
