Answer both questions. Students should show their working clearly. An external reader should be able to follow your calculations to see how you arrived at your answer. 1. A continuous, steady-state process is composed of reaction and separation units with a recycle stream as presented in the following flow diagram: F = 75 mol/h F-100 mol/h X=1 Reactor Product Separator 5,- 100 mol/h *+0.25 * = 0.75 F = ? mol/h XA=0 X=1 *4 = 1 * = 0 * = 0 Fs = ? mol/h XA? X = ? Calculate: a the recycle ratio (mol/mol) (2 marks) b. the flow rate of stream 4 (F4) in mol/h (2 marks) c. the conversion of A per pass (in the reactor) (1 mark) d. the overall conversion of A (1 mark)
