Example: Use the given equilibrium data of methanol (MEOH) and water for solving the simple batch distillation problem with the following description: A single-equilibrium-stage (or a simple) batch still pot is used to separate MEOH from water. The feed with the total amount of 50 moles of an 80 mol% MeOH is charged into the still pot operated at 1 atm. The desired distillate concentration (xa) is 89.2 mol% MeOH. Detemine: a) The total amount of the distillate collected. b) The amount of material (liquid or waste) remained in the pot after the distillation has

Example: Use the given equilibrium data of methanol (MEOH) and water for solving the simple
bateh distillation problem with the following description: A single-equilibrium-stage (or a
simple) batch still pot is used to separate MEOH from water. The feed with the total amount of
50 moles of an 80 mol% MEOH is charged into the still pot operated at 1 atm. The desired
distillate concentration (xa) is 89.2 mol% MEOH. Determine:
a) The total amount of the distillate ecollected.
b) The amount of material (liquid or waste) remained in the pot after the distillation has
ended and its corresponding concentration.
The equilibrium (y -x) data of MeOH is as summarized in the following Table:
