A 50% mass solution of solute A in solvent B is extracted with another solvent S in a countercurrent multiple contact extractor. The mass of S is 65% that of the feed solution. Determine:
a. All the output/input points to the extractor. Use the solvent stream exits with a 20% in solute composition.
b. Calculate the position of the summation stream.
c. Calculate the position of the difference stream (initial liquid stream- liquid stream 1)the system is partially miscible
