Ethylene oxide is produced by the catalytic oxidation of ethylene: C2H4 (g) + 1/2 O2 (g) --> C2H4O (g) An undesired competing reaction is the combustion of ethylene to CO2. The feed to a reactor contains 2 mol C2H4/mol O2. The conversion and yield in the reactor are respectively 25% and 0.70 mol C2H4O produced/mol C2H4 consumed. A multiple-unit process separates the reactor outlet stream components: C2H4 and O2 are recycled to the reactor, C2H4O is sold, and CO2 and...
