A distillation column is fed a liquid mixture of benzene and toluene at the flow rate of 440 kmol/h. The mixture contains 20 mol % of benzene and the rest is balance toluene. The recovery of benzene should be 90 % and the distillate must contain no more than 0.5 % of toluene. Determine the distillate and bottom product rates. Flow rate of the distillate is D =___ kmol/h Flow rate of the bottom product is B =___ kmol/h
