The feed is 100 g/s and contains components A (90%) and N (10%), where N is an inert component. In the reactor, A is converted to B but only partially. The ratio of the concentrations of A to be at the reactor outlet is 3.1. Unreacted A is separated from B and is recycled to the reactor. The separation at the separator is assumed ideal; where all of components A and N separate to B. To avoid accumulation of the inert in the recycle system, the system is purged at the recycle stream but with the cost of loss of A. Find the amount of recycle that results in a loss of A of 9 mol/s. Purge A,N 100 g/s 90% A Reactor Separator Product 10% N
