500675 Chemical and Equilibrium Separation Processes Workshop Nine Question A simple bath still (one equilibrium stage) is used to separate acetone from ethanol. The feed charge to the still pot is 3 kmol of a 60 mol% acetone mixture. The final bottoms concentration of 10 mol% acetone is desired. The pressure of the process is 1 atm. The equilibrium data for acetone-ethanol system at 1 atm is provided in Figure 1. Determine: a) The final charge of material in the still pot, Wrinal. b) The amount of distillate collected, Dtotal. c) The average mole fraction of the distillate, XD, avg Data: Vapour-liquid equilibrium data of acetone-ethanol system is provided in Figure 1 (see next page)
