5. [16 pts] In the process shown below, xylene is recovered from a stream that contains 10 wt% xylene and 90 wt% solids. The stream from which xylene is to be extracted enters Unit 2 at a flow rate of 2000 kg/hr. To provide a solvent for the extraction, pure benzene is fed to Unit 1 at a flow rate of 1000 kg/hr. The mass fractions of the xylene (x) in the solids stream (F) and the clear liquid stream (S) have the following relations: 10 92 10 = (a) [12 pts] Determine the benzene and xylene concentrations in all of the streams. (b) [4 pts] What is the percent recovery of the xylene entering the rocess at Unit 2? S¹ No solid 100 wt% Benzene Unit 1 Unit 2 F² Fl 90 wt% Solids 90 wt% Solids + $² No solid FO 90 wt% Solids
