Title (EN) INTEGRATED PROCESS FOR PRODUCING ETHANOL
(FR) PROCÉDÉ INTÉGRÉ DE PRODUCTION D'ÉTHANOL
Abstract:
(EN) Processes and systems for forming ethanol from methanol. The process involves carbonylating the methanol to form acetic acid and hydrogenating the acetic acid to form ethanol. In a first aspect, at least some hydrogen for the hydrogenating step is derived from a tail gas stream formed in the carbonylation step. In a second aspect, at least some carbon monoxide for the carbonylation step is derived from a vapor stream in the hydrogenation system. In a third aspect, a syngas stream is separated to form a hydrogen stream and a carbon monoxide stream, and the hydrogen stream is methanated to remove residual carbon monoxide prior to being introduced into the hydrogenation system.
(FR) La présente invention concerne des procédés et des systèmes de formation d'éthanol à partir de méthanol. Le procédé implique la carbonylation du méthanol pour former de l'acide acétique et l'hydrogénation de l'acide acétique pour former de l'éthanol. Dans un premier aspect, au moins une partie de l'hydrogène pour l'étape d'hydrogénation est dérivé d'un courant de gaz résiduaire formé dans l'étape de carbonylation. Dans un second aspect, au moins une partie du monoxyde de carbone pour l'étape de carbonylation est dérivé d'un courant de vapeur dans le système d'hydrogénation. Dans un troisième aspect, un courant de gaz de synthèse est séparé pour former un courant d'hydrogène et un courant de monoxyde de carbone, et le courant d'hydrogène est soumis à une méthanation pour éliminer le monoxyde de carbone résiduel avant son introduction dans le système d'hydrogénation.
