You are expected to evaluate the process to determine the operating conditions that will produce a maximum profit under the set constraints discussed in Section 1. You are to determine the operating temperature, pressure, and steam to ethyl-benzene ratio. There are many cases to be evaluated. You should report the profit (or loss) for each case examined and provide stream tables for the best operating conditions found.
Styrene is a vital monomer in the production of thermoplastic. The maximum of it is manufactured by the catalytic dehydrogenation of ethylbenzene. The process depends on rescindable reactions, the yield is typically restricted by the formation of thermodynamic symmetry in the reactor. The styrene yield can be amplified by utilizing a hybrid process, with separation and reaction concurrently. Therefore, I suggest the utilization of permselective compound membrane to eliminate hydrogen and consequently suppress the secondary and reverse reactions.
