The invention, dilution containing the ethanol feed and recycled to comprise at least a portion of the dilution water flow of ethanol, evaporated to the feed to produce a vaporized feed, wherein the evaporated feed water and ethanol step for mixtures dehydration of the evaporation flow of the step for separating a distillate containing effluent water containing the ethylene and the resulting effluent from the dewatering step, and purifying the outlet portion of the water, including water, this includes ethanol obtained from the separation step by means of at least treated water phase for separating the flow of dilution water containing stream with ethanol, partially or completely in the heat exchanger by heat exchange with the resulting quench stream from the oxidation stage evaporation dilution step for recycling at least a portion of the flow and evaporation of the-cold quench the flow after the oxidation step Being recycled to the reactor or the reactor, and a step for the oxidation of ethylene oxy draw of the ethylene contained in the effluent comprising ethylene oxide phase comprises at least one tubular oxidation reactor is cooled by evaporation of the quench stream also - after dewatering, ethanol feed comprising the formation of ethylene, the present invention relates to a method of ethylene to ethylene oxide oxy draw.
