ABSTRACT:
The present invention provides a process for the removal of ethanol from drinks produced by fermentation by direct extraction of the ethanol in countercurrent with compressed carbon dioxide as extraction agent and separation of the extracted water-ethanol mixture from the extraction agent by lowering the density of the compressed gas, wherein, after the lowering of the density, the carbon dioxide is regenerated by a treatment with water and then returned to the extraction step.
