Title (EN) METHOD FOR THE PRODUCTION OF BUTADIENE FROM ETHANOL, INCORPORATING EXTRACTIVE DISTILLATION
(FR) PROCEDE DE PRODUCTION DE BUTADIENE A PARTIR D'ETHANOL INTEGRE AVEC DISTILLATION EXTRACTIVE
Abstract:
(EN) The invention relates to a method for the production of butadiene from an ethanol feedstock, comprising: a step of converting the ethanol into butadiene; a step of separating reagents into a hydrated butadiene effluent, an impurities effluent and an ethanol-butadiene effluent; a step of separating the ethanol-butadiene effluent into a butadiene distillate and a contaminated reagent effluent; a step of purifying the butadiene by means of extractive distillation; and an effluent treatment step.
(FR) L'invention porte sur un procédé de production de butadiène à partir d'une charge éthanol comprenant une étape de conversion de l'éthanol en butadiène, une étape de séparation des réactifs en un effluent butadiène hydraté, un effluent impuretés et un effluent éthanol-butadiène, une étape de séparation séparant l'effluent éthanol-butadiène en un distillât butadiène et un effluent réactifs pollués, une étape de purification du butadiène par distillation extractive et une étape de traitement des effluents.
