Problem 5 Consider an existing distillation column with 12 actual stages, a total condenser, reflux, a reboiler. The reflux ratio is 3. The column internal is sieve tray with a tray spacing of 18in. The feed is a saturated liquid. To achieve the same product specifications the changes in number of equilibrium stages with reflux ratio are calculated below: Nun A vendor suggested that you can retrofit the column by replacing the trays with their packing which has an HETP of 250mm. If such a retrofit is carried out, what is - the new reflux required, - the percentage reduction in condenser duty, and - the percentage reduction in reboiler duty? The following equations from McCabe-Thiele theory can be used
