2. Propane is dehydrogenated to form propylene in a catalytic reactor: C3H3 → C3H6 + H2 The process is to be designed for 85% overall conversion of propane. The reaction products are separated into two streams: the first, which contains H2, C3H6 and 0.656% of the propane that leaves the reactor, is taken off as product, the second stream, which contains the balance of unreacted propane and 5% of the propylene in the product stream, is recycled to the rector. Create a process flow diagram. Calculate the composition of the product, the ratio (moles recycled/ moles fresh feed) and the single-pass conversion.

Steady State Model

The steady-state model typically states that the entire universe is always enlarging, although it balances a fixed average density and matter that is being constantly generated to make new galaxies, star forms at a similar rate that the previous ones get indistinguishable due to the growing range and velocity of recession.
