A trayed tower operating at 1atm is to be designed to

A trayed tower operating at 1atm is to be designed to continuously distill 200kmol/h ( 55.6mol/s ) of a binary mixture of 60mol% benzene, 40mol% toluene. A liquid distillate and a liquid bottoms product of 95mol% and 5mol% benzene, respectively, are to be produced. Before entering the column, the feed-originally at 298K-is flash-vaporized at 1 atm to produce an equimolal vapor/liquid mixture (VF/F=LF/F =0.5 ). A reflux ratio 30% above the minimum is specified. Calculate: (a) The quantity of the products. (b) The minimum number of theoretical stages, Nmin. (c) The minimum reflux ratio. (d) The number of equilibrium stages and the optimal location of the feed stage for the reflux ratio specified
