A column is to be designed to separate acetone-methanol mixture at 1 atm. The feed contains 40 mole% acetone and 60 mole% methanol, and it enters the column as a vapour-liquid mixture of 30% liquid and 70% vapour. The bottoms is to contain 10 mole% acetone and 90 mole % methanol, and the distilate 70 mole% acetone and 30 mole% methanol. A reflux ratio equals to 3 times the minimum is to be used. Determine the number of theoretical trays required for the separation. Repeat the calculations for minimum reflux and theoretical trays (at 3 times minimum) required if the feed is a cold liquid with q = 2.0. Compare your results and comments. Draw a graph and explain Equilibrium data for acetone-methanol at 1 atm are given below: Temperature. °C 64.50 63.50 62.50 60.20 58.65 57.55 56.70 56.00 55.30 55.05 56.10 Mole fraction acetone Liquid Vapour 0.00 0.000 0.05 0.102 0.10 0.186 0.20 0.322 0.30 0.428 0.513 0.586 0.656 0.725 0.800 1.000 0.40 0.50 0.60 0.70 0.80 1.00 A column is to be designed to separate acetone-methanol mixture at 1 atm.
