1000 kg/h of a 30 wt% acetic acid-in-water solution is to be extracted at 20 C and 1 atm in a continuous countercurrent system with pure isopropyl ether to obtain a raffinate containing 10 wt% acetone. The solvent required is 1.5 times the minimum. The mixing point for minimum solvent is (xA,M = 13% , xD,M = 30%). Find out the solvent required for this system. Use the equilibrium miscibility data and tie line data
