Problem $3$

$[35$ points$]$

Acetone is extracted from a $30\%$ acetone $-70\%$ MIBK mixture using water. $200k\frac{g}{h}$ of this mixture is contacted with $300k\frac{g}{h}$ of water in a single equilibrium stage at $25C.$ Phase equilibrium diagram is attached.

a$)$ Draw the process diagram and label all streams.

$[05$ points$]$

b$)$ Determine the composition of both exit streams.

$[10$ points$]$

c$)$ What is the $\%$ recovery of acetone.

$[05$ points$]$

d$)$ A second equilibrium stage is added, in which the resulting MIBK$-$rich phase from the first stage is contacted with $300k\frac{g}{h}$ of water at $25C.$ Determine the composition of both exit streams.

$[10$ points$]$

e$)$ What is the overall recovery of acetone from the original feed stream at the end of two equilibrium stages.
