Question

Ethylene oxide is produced by catalytic oxidation of ethylene and air:

After the reaction, ethylene oxide is completely separated and the remaining gas flow is recirculated. To prevent nitrogen gas from accumulating, part of the recirculation stream is drained off. The  feed consists of pure ethylene and air in the proportions 1:3
The gross conversion (turnover at single pass) of the ethylene is 20% and the nitrogen content in the recirculation stream is 89%.
Calculate
a) Amount of ethylene included to produce 1 ton of ethylene oxide.
b)The net turnover (total turnover) of ethylene.
c)The tap-off ratio, i.e. the ratio between tap-off current and return.
