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