2. Ethylene oxide (C₂H4O) is a high-volume chemical intermediate that is used in the manufacture of textiles, detergents, polyurethane foam, antifreeze, solvents, medicinal, adhesives, and other products like glycol and polyethylene glycol. Ethylene oxide is produced by the partial oxidation of ethylene (C₂H4) using a solid catalyst in a fixed-bed reactor: C₂H4 + O2 →→ C₂H4O An undesired reaction occurs where a portion of the ethylene reacts completely to form CO₂ and H₂O: C2H4 + O2 CO2 + H₂O The product gas leaving a fixed-bed ethylene oxide reactor has the following water-free composition: 22.5% C₂H4O; 70.7% N₂; 2.5% O2; and 4.3% CO₂. Using molecular species balance, determine: a. the percent excess air based on the desired reaction b. the kg/h of the ethylene feed required to produce 75,000 MT/year of ethylene oxide c. the percent conversion of ethylene based on the desired reaction
