Ethylene oxide is produced by the catalytic oxidation of ethylene: 2C2H4 + O2 → 2C2H4O An undesired competing reaction also occurs during this process C2H4 + 3O2 → 2CO2 + 2H2O The feed to the reactor (not the fresh feed to the process) contains 3 moles of ethylene per mole of oxygen. The single-pass conversion of ethylene is 20% and for every 100 mol of ethylene consumed in the reactor, 90 moles of ethylene oxide emerges in the product stream exiting the reactor. A separator is used to separate the reactor products. Three streams emerge from the separator- one stream contains ethylene and oxygen, which are recycled; another stream contains ethylene oxide, which is sold as product, and the third stream contains carbon dioxide and water Choosing 100 mol/ h fed to the reactor as the basis comple the following d. in addition to the ethylene assuming 13.75 moles of oxygen are recycled, detemine the amount of C2H4 in the fresh feed e. calculate the recycle ratio f. what is the selectivity of the process in the reactor, assuming CO2 is your undesired product?

d. in addition to the ethylene assuming 13.75 moles of oxygen are recycled, detemine the amount of C2H4 in the fresh feed
e. calculate the recycle ratio
f. what is the selectivity of the process in the reactor, assuming CO2 is your undesired product?
