Acetone at 45% (mass basis) in water is to be extracted using pure trichloroethylene. The acetone/water flowrate is 10th, and the acetone level is to be reduced to 10% maximum. Use the equilibrium data below on a right-angle triangle construction to answer the following questions. (5) a) Estimate the plait point and mark it with the letter Pin your diagram b) Find the minimum flowrate of solvent c) At a solvent flowrate of 1.5 times the minimum, how many equilibrium stages are required? d) Construct a table, following the example below, showing the mass flowrate of each component in the four streams: Feed, Solvent, Extract, Raffinate. Show the total flowrate of each stream also. (16) Example Acetone Water TCE Total Feed Solvent Extract Raffinate Equilibrium Data: Extract Acetone, Weight Fraction 0.60 0.50 0.40 0.30 0.20 0.10 0.55 0.50 0.40 0.30 0.20 0.10 Water, Weight Fraction 0.13 0.04 0.03 0.02 0.015 0.10 0.35 0.43 0.57 0.68 0.79 0.895 Trichloroethylene, Weight Fraction 0.27 0.46 0.57 0.68 0.785 0.89 0.10 0.07 0.03 0.02 0.01 0.005 Raffinate Tie-line Data: Raffinate, Weight Fraction Acetone 0.44 0.29 0.12 Extract, Weight Fraction Acetone 0.56 0.40 0.18 Hint: Use landscape orientation of the graph paper and place the vertical side of the triangle close to the edge of the graph paper to accommodate the construction. State any assumptions clearly, and use graphical methods to solve parts (a), (b) and (c). You can use Microsoft Excel or ordinary graph paper. TOTAL /35/
