A mixture of 40 mol% carbon disulfide (CS2) in carbon tetrachloride (CC4) is continuously distilled. The feed is 50% vaporized (q = 0.5). The top product from a total condenser is 95 mol% CS2, and the bottoms product from a partial reboiler is a liquid of 5 mol% CS2. The column operates with a reflux ratio, LID, of 4 to 1. The Murphree vapor efficiency is 80%.
(a) Calculate graphically the minimum reflux, the minimum boilup ratio from the reboiler, V/B, and the minimum number of stages (including reboiler).
(b) How many trays are required for the actual column at 80% efficiency by the McCabe-Thiele method. The vapor-liquid equilibrium data at column pressure for this mixture in terms of CS2 mole fractionare
