The invention relates to a separation method, in particular a method for distilling ethanol as a final product from a mash. According to said method, the feed stream is fed to a first distillation stage comprising at least one distillation column (stripper) and the distillate from said first distillation stage is fed to a second distillation column (rectifier). The feed stream is sub-divided into two streams (40, 41) and fed to two distillation columns (1, 2), in such a way that the rectifier (5) maintains a predefined energy balance.
L'invention concerne un procédé de séparation, en particulier un procédé pour distiller l'éthanol contenu dans une trempe, en tant que produit final. Selon ce procédé, un courant d'alimentation est introduit dans un premier étage de distillation comportant au moins une colonne de distillation (colonne de strippage), et le distillat du premier étage de distillation est introduit dans une deuxième colonne de distillation (colonne de rectification). Selon l'invention, le courant d'alimentation est divisé en deux courants (40, 41) au niveau de deux colonnes de distillation (1, 2), de manière que la colonne de rectification (5) atteigne un bilan énergétique prédéterminé.
