Ethylene oxide is produced by the catalytic oxidation of ethylene: 2C₂H4 + 0₂ → 2C₂H4O An undesired competing reaction is the combustion of ethylene: C₂H4 +302 → 2CO2 + 2H₂O The fresh feed to the process contains three moles of ethylene per mole of oxygen. The single- pass conversion of ethylene is 40%, and for every 100 moles of ethylene consumed in the reactor, 80 moles of ethylene oxide emerge 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) Label the flowchart, perform a degree-of-freedom analysis, (b) Calculate the composition of product streams from separation,

Question
Ethylene oxide is produced by the catalytic oxidation of ethylene: 2C₂H4 + O2 → 2C₂H4O An undesired competing reaction is the combustion of ethylene: C₂H4+302 → 2C02₂ + 2H₂O The fresh feed to the process contains three moles of ethylene per mole of oxygen. The single- pass conversion of ethylene is 40%, and for every 100 moles of ethylene consumed in the reactor, 80 moles of ethylene oxide emerge 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.
