Abstract

L'invention concerne un procédé de déshydratation d'une charge éthanol en éthylène comprenant : a) une étape de vaporisation ; b) une étape de chauffe ; c) une étape de déshydratation dans un réacteur multitubulaire comprenant des tubes de longueur entre 2 et 4 m, lesdits tubes comprenant un catalyseur de déshydratation, de préférence zéolithique, la charge ayant une température d'entrée supérieure à 400°C et inférieure à 550°C et une pression d'entrée comprise entre 0,8 et 1,8 MPa, le fluide caloporteur ayant une température d’entrée supérieure à 430°C et inférieure à 550°C et un débit massique tel que le ratio des débits massiques du fluide caloporteur par rapport à la charge est supérieur ou égal à 10 ; d) la séparation en un effluent comprenant de l'éthylène et un effluent aqueux ; e) la purification de l'effluent aqueux et la séparation d'un flux d'eau purifiée et d'un flux d'éthanol non converti.
