A feed, composed of 95 mol% ethylene (C.H.) and 5 mol% ethylene oxide Problem 1 (C:H.O) is fed to a reactor through stream #1, where the oxidation reaction with pure O:occurs. Ethylene reacts according to the following two reactions, where the first reaction produces the desire product (ethylene oxide, C:H.O) and the second reaction produces undesired products. The overall reaction conversion is 80% and the reaction yield is 60%. In addition, 10% excess O, is used in the reactor (stream #2).
