A wastewater stream flowing at $10\mathrm{.}0$kmo$\frac{l}{h}r$ at $20C$ and $1$atm and contains $6\mathrm{.}0$mole$\%$ acetone. It is desired to remove $95\%$ of the acetone in the wastewater stream using Iq$-$Iq extraction with the column operating at $20C$ and $1$atm. Pure chlorobenzene $(C_6{H}_{5}Cl)$ is to be used as the extraction solvent for this unit.

a$)$ Draw a flow diagram for this process $[2$ pts$]$

b$)$ Use the equilibrium data below to estimate a $K$ value for this process $[2$pts$]$

c$)$ Use the Kremser equations to estimate the number of stages required if a solvent flowrate of $1\mathrm{.}5$ times the minimum value is utilized. $[6$ pts$]$

Equlibrium data

Useful equations:

$N=\frac{1}{lnlo{n}_i}ln[\frac{1-\frac{\frac{O}{{?}_i}}{lo{n}_i}}{1-\frac{O}{{?}_i}}],lon=\frac{K**S^{\text{'}}}{F^{\text{'}}},S_{\text{m}\text{i}\text{n}}^{\text{'}}=\frac{F^{\text{'}}**\frac{O}{{?}_i}}{K_i}$
