A continuous, steady-state distillation column with a total condenser and a partial reboiler separates methanol from water at one atmosphere total pressure. The feed rate to the column is Fib-mole/hour and the feed temperature is maintained at T, C. The feed contains mwF mass % methanol and wwf mass % water. A distillate product contains mwD mass % methanol and a bottoms product contains mmB mole % methanol. The external reflux ratio L/D is rd.
