Abstract
Dehydrating an ethanol feed to form ethylene then oxidation of the ethanol to ethylene oxide: vaporization of an ethanol feed and at least a portion of a flow of diluting water comprising recycled ethanol so as to produce a vaporized feed, compression in a compressor driven by a condensing turbine driven by the steam generated by an oxidation step, dehydration of a mixture of compressed vaporized feed, separation of effluent obtained from dehydration into ethylene and water, purification of at least a portion of effluent containing water and separation into at least a flow of treated water and a flow of diluting water containing ethanol, recycling the latter upstream of the vaporization, oxidation of ethylene containing in the effluent into ethylene oxide, in at least one tubular oxidation reactor cooled by vaporization of a quench flow, said vaporized quench flow being used to drive a condensing turbine.
