Question: Acetone is to be extracted from a solution containing 4 6 w t % acetone and 5 4 w t % water by using pure

Acetone is to be extracted from a solution containing 46wt% acetone and 54wt%
water by using pure chlorobenzene as solvent in a multistage counter current
operation. The final raffinate should not contain more than 6% of solute. Compute the
no. of ideal stages required. The feed and solvent rate are 1000kghr and 1300kghr,
respectively. The equilibrium diagram is attached. The equilibrium data is also given
as follows:
