Chapter 6, Problem 6.105P

Interpretation Introduction

Interpretation:

To determine amount of acetone in the feed solution would be removed and composition of the combined extraction.

Concept introduction:

A mixture containing $30\%\text{acetone}\left(x_{a,feed}\right)$ and $\text{70\% MIBK}$ is sent into an extraction unit-1 with a flow rate, ${\text{<mover accent="’true'"><mi>m</mi><mo>˙</mo></mover>}}_{\text{feed}}(200\text{kg/h})$.

A water stream is sent into the unit with flow rate, ${\dot{m}}_{{}^{H_{2}O}}(300\text{kg}{\text{H}}_{\text{2}}\text{O/h})$ to obtain an extract solution having flow rate, ${\dot{m}}_{{}^{ex{t}_1}}$ and a raffinate solution having flow rate, ${\dot{m}}_{{}^{ra{f}_1}}$.
