Problem 2 (25 PTS). In a single-stage liquid-liquid extraction, a feed (A) containing 50wt% of solute (B) enters a single stage extractor at a total flow rate of 1,000kg/h and is contacted with 1,500 kg/h solvent (C). Using the ternary phase diagram on the next page, answer the following questions (show all calculations for partial credit and label the diagram). i. On the phase diagram (next page), label the mixture (M), feed (F), solvent (S), extract (E), and raffinate (R) compositions directly on the graph. ii. What is the mass fraction of solute in the raffinate? iii. What is the mass fraction of solute in the extract? iv. What is the total mass flow rate of extract, E? v. What is the partition coefficient, KD ', of solute (mass basis)
