02: Ethylene oxide is produced by the catalytic oxidation of ethylene: 2C:Ha + 02 - → 2C:H.0 An undesired competing reaction is the combustion of ethylene: CH. + 30:- + 2C0: + 2H:O The feed to the reactor (not the fresh feed to the process) contains 3 moles of ethylene per mole of oxygen. The single-pass conversion of ethylene is 30%, and for every 100 moles of ethylene consumed in the reactor, 90 moles of ethylene oxide emerges in the reactor products. A multiple-unit process is used to separate the products: ethylene and oxygen are recycled to the reactor, ethylene oxide is sold as a product, and carbon dioxide and water are discarded. Assume a quantity of the reactor feed stream as a basis of calculation, calculate (a) the molar flow rates of ethylene and oxygen in the fresh feed, (b) the production rate of ethylene oxide, and (c) the overall conversion of ethylene.
