| titleOfInvention | Low-energy consumption method for dehydrating ethanol into ethylene |
| abstract | The present invention describes a process for dehydrating an ethanol load to ethylene and is characterized in that it comprises the step of heating said ethanol load in a mixture having at least a portion of the purified water stream recycled according to step f) in the exchanger as a result of heat exchange with the effluent from the last reactor Vaporizing said mixture, said vapor being introduced into the vaporization step at a pressure of from 0.1 to 0.4 MPa, compressing the vaporized mixture in a compressor, at least one dehydration catalyst comprising at least one Introducing the vaporized and compressed mixture at an inlet temperature of 350 to 500 ° C and an inlet pressure of 0.2 to 1.3 MPa in an adiabatic reactor, feeding the effluent from the last adiabatic reactor of step c) into a effluent containing ethylene at a pressure of less than 1 MPa And an effluent solution comprising water, from step d) Separating at least one flow of purified water and at least one flow of unconverted ethanol, and separating at least a portion of the flow of purified water from step a) from step a) And recycling it upstream. |
