[object Object]

Process for dehydrating an ethanol feed to ethylene then oxidating the ethanol to ethylene oxide, comprising vaporizing the feed and a flow of diluting water comprising recycled ethanol to produce a vaporized feed, dehydrating a mixture of vaporized feed and a vaporized flow of diluting water comprising ethanol, separating the dehydration effluent into ethylene and water effluents, purifying at least a portion of the water effluent and separating a flow of treated water and a flow of diluting water comprising ethanol, recycling and vaporizing at least a portion of the separated diluting water by partial or complete vaporization in an exchanger using heat exchange with a quench flow obtained from the oxidation, said quench flow, cooled, then recycled to the oxidation reactor(s), and oxidation of the ethylene in the effluent comprising ethylene into ethylene oxide, this oxidation using a tubular oxidation reactor cooled by vaporization of said quench flow.
