Title
(EN) METHODS AND APPARATUS FOR SEPARATING ETHANOL FROM FERMENTED BIOMASS
(FR) PROCÉDÉS ET APPAREIL POUR SÉPARER L'ÉTHANOL D'UNE BIOMASSE FERMENTÉE
Abstract
(EN)
A method for separating ethanol from fermented biomass is provided. Fermented biomass that is rich in ethanol is used directly as packing material in a distillation column, and a small amount of water at the bottom of the column is used to efficiently transfer heat to the biomass at the bottom of the column. The fermented biomass packing has a high ratio of surface area to volume, making an efficient packing material. As vapor condenses on the biomass, diffusion of ethanol/water vapor from the body of the biomass enriches the ethanol concentration at the surface of the biomass. Droplets containing lower concentrations of ethanol drip downwards from the biomass, and vapors containing higher concentrations of ethanol rise upwards from the biomass, resulting in a higher concentration of ethanol at the top of the column than was initially in the biomass.

La présente invention concerne un procédé de séparation d'éthanol à partir de biomasse fermentée. La biomasse fermentée qui est riche en éthanol est utilisée directement comme matériau de garnissage dans une colonne de distillation, et une petite quantité d'eau au fond de la colonne est utilisée pour transférer efficacement de la chaleur à la biomasse au fond de la colonne. La garnissage de biomasse fermentée a un rapport élevé entre la surface et le volume, ce qui rend le matériau de garnissage efficace. A mesure que la vapeur se condense sur la biomasse, la diffusion d'éthanol/vapeur d'eau à partir du corps de la biomasse enrichit la concentration en éthanol à la surface de la biomasse. Des gouttelettes contenant des concentrations basses en éthanol tombent vers le bas à partir de la biomasse, et des vapeurs contenant des concentrations plus élevées en éthanol montent à partir de la biomasse, ce qui permet d'obtenir une concentration plus élevée en éthanol au sommet de la colonne qu'auparavant dans la biomasse.
