A distillation column operating at 101.3kPa is used to separate a saturated liquid mixture of benzene and toluene. The optimum reflux is found to be 3.5. The feed contains 55 mol\% benzene and fows at 100kmol/hr. You desire a distillate containing 95 mol\% benzene and a bottoms containing no more than 10 mol\% benzene. The equilibrium data for this system at 101.3kP aare given in the table above. A. Calculate the flowrate of the distillate and bottoms [5] B. Determine the number of theoretical trays needed [25]
