Eihylene oxide is produced by the catalytic oxidation of ethylene: an undesired competing reaction is the combustion of ethylene: c2h4 + 02co2+h2o the feed to the reactor contains 4 moles of ethylene per mole of oxygen. the single pass conversion ofethylene is l 5% and for every 100 moles of ethylene consumed in the reactor, 80 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. a) assume a quantity of the reactor feed stream as a basis of calculation and draw and label a flow diagram. b) calculate the molar flow rates of ethylene and oxygen in the fresh feed, the production rate of ethylene oxide, the molar flow rates of the recycle stream, the molar flow rates of carbon dioxide and water exiting the system, and the overall conversion of ethylene.
