1000.0 mol/h of a 40.0 mol% benzene and 60.0 mol% toluene is fed into a distillation column with a total condenser and a partial reboiler. The feed is a saturated liquid. CMO is valid. Distillate is 99.3 mol%, benzene and bottoms is 1.0 mol% benzene. Use the Fenske equation to find the number of stages required at total reflux, a McCabe-Thiele diagram to find (L/D)min, and the Gilliland correlation to estimate the number of stages required if L/D = 1.15(L/D)min. Relative volatility is constant, Apt = 2.4. Check your results with a McCabe-Thiele diagram. =
