Title (EN) PROCESS FOR PRODUCING ETHANOL
(FR) PROCÉDÉ DE PRODUCTION D'ÉTHANOL
Abstract: front page image
(EN)A crude ethanol product obtained from the hydrogenation of acetic acid comprises ethanol and ethyl acetate. Using a distillation column operated at a pressure of from 0.1 to 100 kPa, the ethyl acetate and ethanol may be effectively separated. In addition, maintaining the amount of water that is fed to the distillation column to an amount less than 10 wt.%, based on the weight of all components fed to the distillation column, provides an energy benefit.
(FR)La présente invention concerne un produit d'éthanol brut obtenu par l'hydrogénation de l'acide acétique comportant de l'éthanol et de l'acétate d'éthyle. L'utilisation d'une colonne de distillation fonctionnant à une pression comprise entre 0,1 et 100 kPa permet la séparation efficace de l'acétate d'éthyle et de l'éthanol. En outre, le maintien de la quantité d'eau qui est alimentée à la colonne de distillation à une quantité inférieure à 10% en poids, par rapport au poids total des composants alimentés à la colonne de distillation, fournit un bénéfice d'énergie.
