Q$2)(35$ pts$)$ Below process diagram is given for the separation of benzene $($B$)$ and cumene $($C$).$

a$)(10$ pts$)$ Fill in the blanks $(.....)$ in above diagram by conducting material balanced. Benzene product from the $1^{st}$ column is slightly contaminated by cumene $(1$kmo$\frac{l}{h}).$ Cumene mole percent in the bottom of the $2^{nd}$ column is $25\%.$

b$)(25$ pts$)$ Calculate $N_{\text{m}\text{i}\text{n}}$ and $R_{\text{m}\text{i}\text{n}}.$ Antoine Equation coefficients are given below. $($take $q=0\mathrm{.}2)$

$\backslash$table$[[,$Antoine Coefficients$],[$Component$,$A$,$B$,$C$],[$B $($Non$-$Key$),15\mathrm{.}9,2,789,-52\mathrm{.}4],[$C $($Light Key$),16,3,364,-63\mathrm{.}4],[$D $($Heavy Key$),17\mathrm{.}3,4,732,-40\mathrm{.}2]]$

$ln{P}^{\text{s}\text{a}\text{t}}=A-\frac{B}{T+C}$

$(T$ is in Kelvin and $P$ is in $mmHg)$

Note that the bottom of the first column $($also the feed to the $2^{nd}$ column$)$ and the top of the $2^{nd}$ column is at $179C$ and the bottom of the $2^{nd}$ column is at $217C.$
