Dehydration of ethanol to ethylene production

The present invention relates to a method for producing ethanol dehydration to ethylene, mainly solves the prior art of organic wastewater dehydration of ethanol to ethylene production not adequately treated, for the purpose of resource utilization, or despite treatment, the presence of complex process, the flow long, large investment issues. By using the present invention comprises the steps of: a) contacting the vapor phase dehydration reaction of ethanol with the catalyst to generate a reaction gas containing ethylene; b) quenching the reaction gas into the cooling tower wash; c) washing the quench fluid into the stripping distillation tower stripping distillation, to obtain an overhead stream containing organic matter, to give an aqueous bottoms stream; D) an aqueous bottoms stream through the water processor, can obtain resource utilization of process water technical solution solves the problem, ethanol dehydration can be used in the industrial production of ethylene.
