Question:
A distillation column that has a total condenser and a partial reboiler is fed 500 kmol/h of an equimolar mixture of pentane and hexane. The feed is saturated liquid. It is necessary to produce outlet streams containing 95 mol% pentane and 99 mol% hexane. The distillation column contains a partial reboiler and a total condenser and operates at 1.4 times the minimum reflux ratio, which is a reflux ratio of 1.06. It has been determined that the column requires 15 equilibrium stages with the feed on Stage 5. The pressure at the bottom of the column is 2 bar. Assume that the McCabe-Thiele approximation is valid.
1. Determine the exit flowrates, D and B.
2. Determine all of the internal flowrates.
3. Determine the required column diameter for sieve trays with a 24-
in tray spacing operating at 75% of flooding with 88% active area.
