Use the binary diagram, 45 line above and material balance to solve the One thousand kg/h of a (50-50 wt%) acetone-in-water solution is to be extracted at 25C in a continuous, countercurrent system with pure 1,1,2-trichloroethane to obtain a raffinate containing 10 wt% acetone. Using the following equilibrium data, determine with an equilateral-triangle diagram: a the minimum flow rate of solvent; b. the number of stages required for a solvent rate equal to 1.5 times minimum, and composition of each streamleaving each stage.
