- Q. VI: An equimolar liquid mixture of benzene and toluene is separated into two product streams by distillation. At each point in the column some of the liquid vaporizes and some of the vapor stream condenses. The vapor leaving the top of the column, which contains 97 mole% benzene, is completely condensed and split into two equal fractions: one is taken off as the overhead product stream, and the other (the reflux) is recycled to the top of the column. The overhead product stream contains 89.2% 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 compositions of the streams leaving the reboiler are governed by the relation, YB/(1 - YB) XB/(1 - XB) = 2.25 where YB and XB are the mole fractions of benzene in the…arrow_forward1.
