7.4 Summary—Objectives

In this chapter we developed approximate shortcut methods for binary and multicomponent distillation. You should be able to satisfy the following objectives:

1. Derive the Fenske equation and use it to determine the number of stages required at total reflux and the splits of NK components

2. Use the Underwood equations to determine the minimum reflux ratio for multicomponent distillation

3. Use the Gilliland correlation to estimate the actual number of stages in a column and the optimum feed stage location
