2. (20 points) An inlet water solution of 800 kg/h containing 12.0 wt% acetone is extracted with the solvent trichloroethane containing 0.5 wt% acetone at 25C. The solvents water and trichloroethane are essentially immiscible in each other up to a concentration of acetone in water of 27 wt %. (a) Determine the percentage extraction of acetone if the feed solution is extracted once with 500 kg/h solvent. (b) Repeat for two theoretical extractions using 250 kg/h solvent each. Use equilibrium data presented in Handout # 11.
