One hundred kilogram-moles per hour of a three-component bubble-point mixture to be separated by distillation has the following composition:

(a) For a distillate rate of 60kmol/h, five theoretical stages, and total reflux, calculate the distillate and bottoms compositions by the Fenske equation.

(b) Using the separation in part (a) for components B and C, determine the minimum reflux and minimum boilup ratio by the Underwood equation.

(c) For an operating reflux ratio of 1.2 times the minimum, determine the number of theoretical stages and the feed-stagelocation.
