Abstract: A process for producing ethylene oxide wherein a portion of the gases produced in the process are combusted with supplementary fuel to produce products of combustion that drive a gas turbineair compressor. The compressed air from the air compressor is returned to the ethylene oxide reactor to be used in the production of ethylene oxide.
