1,1,2-trichloroethane - acetone solution containing 42% acetone by weight at a flow rate of 1200 kg/h will be extracted in a countercurrent multistage extraction system with water at a flow rate of 2100 kg/h at 25°C. The water is not pure and contains 2% by weight of 1.1.2-trichloroethane. Since acetone in the raffinate phase is not to exceed 5% by weight; a. The amount and composition of the extract and raffinate phase, b. The percent recovery of acetone, c. Calculate the theoretical number of steps required.
