Physics

A liquid mixture of benzene-toluene is to be distilled in afractionating tower at 101.3 kPa pressure. The feed of 100 kg mol/his liquid, containing 45 mol benzene and 55 mol% toluene, andenters at 327.6 K. A distillate containing 95 mol benzene and 5 moltoluene and a bottoms containing 10 mol benzene and 90 mol tolueneare to be obtained. The reflux ratio R is 4: 1. Determine the kgmoles per hour distillate, kg moles per hour bottoms, number oftheoretical trays needed, feed tray location, condenser andreboiler heat loads, minimum number of stages (i.e., total reflux),and minimum reflux ratio Rmin (i.e., infinite number ofstages).
