A mixture, F, of 620 lbmol/h of 46 mol% benzene (B) and 54 mol% toluene (T) is separated continuously into two products. One product, the distillate , is 98 mol% benzene. The other product, the bottoms , is 95 mol% toluene. Compute the flow rates of these two streams in: (a) lbmol/h, and (b) kmol/h. Calculate the fraction of the benzene fed to the unit that is recovered in the distillate.
