The column will operate at a pressure of 760 mmHg and the feed will be preheated to 70 °C. For this separation, determine:

a. The minimum number of stages required

b. The minimum reflux ratio

c. The number of theoretical stages for a reflux ratio 1.5 times the minimum

d. The number of actual stages if the plate efficiency can be taken as 60%
