A feed to a distillation column consisting equimolar benze and toluene is separated into two product streams by fractional distillation. The fresh feed stream flow is 90mol/hr. The vapor leaving the top of the column contains 90% benzene, is completely condensed into two equal fractions wherein one is removed as overhead product stream and the other (reflux) is recycled to the top of the column. The overhead produt stream contains 85% of the benzene fed to the column.
 
The liquid leaving the bottom of the column is fed to a partial reboiler in which 45% of it is vaporized. The vapor generated in the reboiler (the boilup) is recycled to become the rising vapor stream in the column, and the residual reboiler liquid is taken off as the bottom product stream. The relation that governs the composition of the sreams leaving the reboiler is
YB=2.25xB
