Title (EN) PROCESS FOR EXPLOITING GAS EFFLUENTS FROM ALCOHOLIC FERMENTATION
(FR) PROCÉDÉ DE VALORISATION DES EFFLUENTS GAZEUX ISSUS DE FERMENTATION ALCOOLIQUE
Abstract:
(EN) The present invention relates to a process for exploiting gas effluents from alcoholic fermentation, comprising: - a step of alcoholic fermentation in a bioreactor producing a fermented matter and a gas effluent, wherein the gas effluent comprises carbon dioxide; - a step of extraction of the gas effluent from the bioreactor, followed by compression thereof, in order to obtain a compressed gas effluent; and - a step of production of an alkali metal bicarbonate suspension in a bicarbonate production unit, wherein the bicarbonate production unit is divided into at least two compartments arranged successively in series. The present invention also relates to a corresponding facility.
(FR) La présente invention concerne un procédé de valorisation des effluents gazeux issu de fermentation alcoolique comprenant : - une étape de fermentation alcoolique dans un bioréacteur produisant une matière fermentée et un effluent gazeux, l'effluent gazeux comprenant du dioxyde de carbone; - une étape d'extraction de l'effluent gazeux du bioréacteur suivi de sa compression, afin d'obtenir un effluent gazeux comprimé; et, - une étape de production d'une suspension de bicarbonate alcalin dans une unité de production de bicarbonate, l'unité de production de bicarbonate étant divisée en au moins deux compartiments disposés successivement en série. La présente invention concerne également une installation correspondante.
