Please solve this include detials. detailsA Distillation column is to be designed to split components shown in feed below to the stream

flows given in the columns for $d$ and $b.N-$Pentane is the light key and $n-$hexane is the heavy key.

Feed is saturated liquid, and the flows are in kmo$\frac{l}{s}.$ Temperature for the feed, assumed products

and the relative volatilities for the respective stream are given.

a$)$ Confirm by calculations that bn$-$butane is expected to be zero for minimum reflux at the

given conditions. Hint: Use underwood equation at minimum reflux and use avg

alpha$/$mean alpha.

b$)$ What is the minimum number of stages to carry out the specified separation?

c$)$ Write out the equation $($All the terms, not the summation notation$)$ that are used to

determine R$\_$min using Shiras method, and insert know values for all variables that would

verify that the $R_{m}in=1\mathrm{.}18$ and $=1\mathrm{.}44.$ You are not expected to solve for any values.
