Solve parts D$-$F A saturated liquid feed of $200mo\frac{l}{h}$ at the boiling point containing $50$mol$\%$ heptane and $50$mol$\%$ ethyl benzene is to be distilled at $101\mathrm{.}32$kPA abs$.$ The distillate should be designed to contain $98$mol$\%$ heptane and the bottoms containing $1$ mol$\%$ heptane.

The reflux ratio to be used should be $1\mathrm{.}8$:$1.$ Equilibrium data is given in the Table below.

Do the following:

a$)$ Draw the schematic diagram

b$)$ Calculate the $mo\frac{l}{h}$ of distillate and $mo\frac{l}{h}$ bottom flowrates,

c$)$ Determine the minimum reflux ratio and the minimum number of stages

d$)$ Determine theoretical number of trays and

e$)$ Determine the feed tray number.

f$)$ If the Murphree efficiency is determined to be $0\mathrm{.}6,$ recalculate the number of trays required.
