The process is to be designed for an 80% overall conversion of propane. The reaction products are separated into two streams: the first, which contains Hz gas, propylene (C3H6), and 0.5% of the propane that leaves the reactor, is taken off as product; the second stream, which contains the balance of the unreacted propane, 7% of the propylene in the product stream, and no H3, is recycled to the reactor. Calculate the flow rates and compositions of all streams and the single pass conversion of propane in the reactor.
