distillation column with a total condenser and a partial reboiler is used to parate an acetone-acetic acid mixture. The feed, F, is saturated liquid ntaining 50 mole % acetone (x=0.95), and the desired bottoms composition 2 mole\% acetone (xB=0.02). The external reflux ratio is 2 and the reflux is turated liquid. The column pressure is 1atm. Find and draw the equilibrium data of the system and then find the optimum number of stages required to achieve the separation? What is the minimum reflux ratio and the minimum number of stages required to achieve the separation
