A solid waste processing plant has two classifiers that produce a refuse-derived fuel (RFD) from a mixture of organic (A) and inorganic (B) refuse. A portion of the plant schematic

and the known flow rates are shown in the Figure below. a. What is the flow of A and B from Classifier I to Classifier II [QA2 and QB2] b. What is the composition of the Classifier II exit stream (OA3 and OB3)? c. What is the purity of the RFD and the recovery of component A?
