A water-acetone mixture ( 45wt% acetone in the feed) is purified by liquid-liquid extraction in a multistage system with a 1,1,2-trichloroethane solvent to produce a water-acetone raffinate that contains only 10wt% acetone. The water-acetone mixture is fed into the system at a rate of 1000kg/h. Use the Hunter-Nash graphical equilibrium method together with the equilibrium data below to find: 1. The minimum solvent flow rate. 2. The number of stages required for a solvent flow rate equal to 1.5 times this minimum. 3. The composition of each stream leaving each stage. Note that equilateral triangle graph paper is included on the next two pages. Table 1: Weight fraction of each component Table 2: Tie-line data
