E1. A mixture of methanol and water is being separated in a distillation column with open steam (see figure in Problem 3.D2). The feed rate is 100 kmol/h. Feed is 60.0 mol% methanol and is at 40 °C. The column is at 1.0 atm. The steam is pure water vapor (yM = 0) and is a saturated vapor. The distillate product is 99.0 mol% methanol and leaves as a saturated liquid. The bottoms is 2.0 mol% methanol and, since it leaves an equilibrium stage, must be a saturated liquid. The column is adiabatic. The column has a total condenser. External reflux ratio is L/D = 2.3.
