ABSTRACT OF THE DISCLOSURE In the recovery of ethylene oxide from the gas resulting from catalytic gas-phase oxidation of ethylene with a molecular oxygen-containing gas and consequently containing ethylene oxide, a method which comprises subject- ing the bottom liquid of an ethylene oxide stripper to a flushing treatment thereby separating the bottom liquid into a vapor-phase part and a liquid-phase part, introducing the vapor-phase part in a compressed state into the bottom of the ethylene oxide stripper, and circulating the liquid- phase part to the absorber. The liquid-phase part, after exchanging heat with the bottom of the ethylene oxide absorber, is caused by a heat pump to liberate thermal energy and generate steam. Further, the liquid-phase part can be used as a heat source for the ethylene oxide refiner and/or the light ends stripper. Moreover, the gas from the top of the ethylene oxide stripper can be used as a heat source for the ethylene oxide refiner.
