A liquid feed of 100kgmol/h of benzene-toluene at the boiling point contains 55mol% benzene and 45mol% toluene. It is being distilled at 1 atm pressure to give a distillate with xD=0.95 and a bottom of xW=0.05. Using a reflux ratio of 1.3 times the minimum and Ponchon Savarite method: a. Determine the theoretical number of trays needed. xy equilibrium data as shown below. b. Calculate the condenser and reboiler duties. c. Determine the minimum number of trays at total reflux. Explain why Nmin doesn't depend on the feed conditions. Enthalbv concentration diagram data for benzene (A)-toluene (B) mixtures at 1atm
