A 1000 kmol/h mixture of A and B enters a distillation column at its boiling point. The mixture is 60 mol% A. The compositions of the more volatile component are 0.95 and 0.05 in distillate and bottom streams respectively. The column is fitted with a total condenser and partial reboiler. The reflux ratio is three. Figure 1 shows the vapor liquid equilibria for this mixture. Perform the following:

a) Draw a schematic diagram of the distillation column

b) Determine the flow rates of top, D, and bottom, B, streams

c) Determine the flow rate of the rectifying section vapor and liquid streams

d) What is the operating line equation of the upper section?

e) Draw the operating lines of the rectifying and stripping sections

f) Find the theoretical number of stage
