The following are known information for the separation of a benzene-toluene system at 1 atm using distillation with reflux: Feed (F): 450 lbmol/h 60 mol% benzene 40 mol% toluene %molar vaporization due to preheating is equal to the D/F ratio Tops (D): 95% benzene Bottoms (B): 5% benzene Using the McCabe-Thiele Method, determine the ff: A) Minimum reflux ratio B) Minimum number of stages (For C-E, use a different equilibrium diagram) C) Number of equilibrium stages for a reflux to minimum reflux ratio of 1.3 D) Optimal feed stage location E) Actual Number of Trays if efficiency is 80%
