A solution of 6 % acetaldehyde in toluene is to be extracted with water in a 4 stage cross current unit for 125 kg feed. The solvent used in the 1st, 2nd, 3rd, 4th stages are 10, 15, 20, 25 kg of water respectively. Assume solvents are immiscible. The equilibrium relation is Y = 2.1 X, where Y is kg acetaldehyde / kg water and X is kg acetaldehyde / kg toluene. Determine: (i) The percentage recovery of acetaldehyde in each stage and overall percentage of acetaldehyde recovery (ii) What is the percentage of acetaldehyde recovery for single batch operation, If 70 kg of water is used.
