The present invention is for the production of fuel grade alcohol, specifically ethanol. A steam dryer is used to dry the solid byproduct into usable animal feed. The steam dryer typically contains less than 6% air in its exhaust stream is directed to the bottoms of one or more distillation columns to heat the distillation column and scrub the exhaust stream simultaneously. The elimination of a thermal oxidizer and the efficient use of the energy in the exhaust stream provide considerable cost savings for an alcohol production plant.
La présente invention concerne la production d'alcool de qualité combustible, en particulier d'éthanol. Un sécheur à vapeur d'eau est utilisé pour sécher le sous-produit solide en aliment pour animaux utilisable. Le sécheur à vapeur d'eau contient généralement moins de 6 % d'air dans son courant effluent qui est adressé vers le fond d'une ou plusieurs colonnes de distillation pour chauffer la colonne de distillation et laver simultanément le courant effluent. L'élimination d'un oxydeur thermique et l'utilisation efficace de l'énergie dans le courant effluent fournissent d'importantes économies de coût pour une installation de fabrication d'alcool.
