Design a chemical reactor to produce 500 kg of ethylene oxide per hour from ethylene and oxygen gases. Assume the reaction occurs isothermally, and the reactor operates at 3 atm and 250°C. The conversion of ethylene to ethylene oxide is 90%, and the selectivity of ethylene oxide is 97%. You can use either a plug-flow reactor or a continuous stirred-tank reactor. Determine the volume and dimensions of the reactor, and also its cost, assuming a stainless steel construction.
