Example 5.5 Propane is dehydrogenated to form propylene in a catalytic reactor: C,H. C,H. + H2 The process is to be designed for a 95% overall conversion of propane. The reaction products are separated into two streams: the first, which contains H, CHe, and 0.555% of C,Ha that leaves the reactor, is taken off as product; the second, which contains the balance of the unreacted propane and 5% of the propylene in the first stream, is recycled to the reactor. Calculate (a) the composition of the product, (b) the ratio: (moles recycled)/(moles fresh feed), and (c) the "single-pass" conversion. CaHa-n.
