A distillation column is fed a liquid mixture of benzene and toluene at the flow rate of 540540 kmol/h. The mixture contains 3838 mol % of benzene and the rest is balance toluene. The distillate must contain no more than 0.40.4 mol % toluene and the bottom product must contain no more than 0.10.1 mol % benzene.

Determine the distillate and bottom product rates and the recovery of benzene.

Flow rate of the distillate is D =_____ kmol/h

Flow rate of the bottom product is B =____ kmol/h

Recovery of benzene is_____ %
