[object Object]

A process for dehydration of an ethanol feedstock into ethylene, comprising the vaporization of said ethanol feedstock in a mixture with at least a portion of the recycled purified water stream from heat exchange with the effluent that is obtained from the last reactor.

Process for dehydration of ethanol into ethylene with low energy consumption

A process for dehydration of an ethanol feedstock into ethylene, comprising the vaporization of said dilute hydrated ethanol feedstock in an exchanger, with heat exchange with the effluent that is obtained from a last reactor, with said mixture being introduced into said vaporization stage at a pressure that is lower than the pressure of the effluent that is obtained from the last reactor, the compression of the mixture that is vaporized in a compressor, the introduction of the vaporized and compressed mixture, into at least one adiabatic reactor that contains at least one dehydration catalyst.
