Question

Please Solve part of A , B

Tipe 1 : The condenser is (total) throughout the problem. But the reboiler is (total) when you want to calculate Nmin, and it is (partial) when you want to calculate N.

Tipe 2 : The purpose of this exercise is to plot the data and solve this question graphically, and FUG theory and the use of fixed alpha relationships are not the answer here.

kmole
A total feed of 100
having an overall composition of 45 mol % toluene and 55 mol %
hr
benzene is to be fractionated at 101.3 kPa pressure to give a distillate containing 95 mol % benzene
and a bottoms containing 2 mol % benzene. The feed enters the tower partially vaporized so that
