Design a Chemical Reactor for the Hydrogenation of Benzene to Cyclohexane:Given the reaction between benzene and hydrogen gas to produce cyclohexane (C6H6 + 3H2 -> C6H12), design a chemical reactor that can convert 900 kg/hr of benzene to cyclohexane, assuming a 90% conversion is desired. The reactor should operate at 300°C and 20 atm, and the hydrogen flow rate is limited to 3000 kg/hr. Determine the reactor type, size, and necessary parameters such as heat transfer, pressure drop, and residence time.
