Process for exploiting gas effluents from alcoholic fermentation

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 gaseffluent, 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. 本发明涉及酒精发酵产生的气态流出物的增值利用方法，包括：-在生物反应器中进行酒精发酵的步骤，产生经发酵的物质和气态流出物，所述气态流出物包含二氧化碳；-从所述生物反应器中提取该气态流出物然后对其进行压缩的步骤，以获得压缩的气态流出物；-在碳酸氢盐生产单元中生产碱性碳酸氢盐的悬浮液的步骤，该碳酸氢盐生产单元被分为至少两个串联相继布置的隔室。本发明还涉及相应的设备。
