Question:
For the complex distillation operation shown in figure 9.22, use the Fenske equation to determine the minimum number of stages required between:
(a) The distillate and feed,
(b) The feed and the side stream, and
(c) The side stream and bottoms. The K-values can be obtained from Raoult's law.
