A valuable product (P) is to be extracted from a crude product stream in a processing plant. The crude product stream contains 30% product and 70% other compounds (I). The product is to be extracted using a solvent (S) and purified according to the processing scheme shown in the following fully-labeled flowchart. Note that all concentrations are listed as mass fractions. The overall recovery of the product in the purified product stream (stream 3) is 95%. 99% of the solvent in the feed to the Separator is recovered in the recycle stream. 80% of the product in the feed to the Separator is recovered in the product stream. Calculate all unknown concentrations and flow rates.
