High pressure recovery of carbon dioxide from a fermentation process

A method for recovering carbon dioxide from a gaseous carbon dioxide stream originating from a fermentation process, brewery or a bottling line, the method comprises the steps of:

• a) providing the carbon dioxide stream originating from the fermentation process, brewery or bottling line;
• b) compressing the provided carbon dioxide stream by at least one compression step providing a compressed gaseous stream;
• c) subjecting the compressed gaseous stream to an absorption step providing at least a carbon dioxide rich gaseous stream, wherein the absorption step comprises liquid carbon dioxide as an absorbent;
• d) condensing the carbon dioxide rich gaseous stream in a condenser providing at least a condensate and a purge gas;
• and
• e) distilling the liquid carbon dioxide stream to provide purified carbon dioxide, wherein the pressure of the compressed gaseous stream obtained in step b) is at least 30 bar, the temperature is within a range where there is substantially no condensation of carbon dioxide and that said pressure is maintained to at least step d),
• wherein the condensation of step d) is performed by a coolant used in the brewery, fermentation process or bottling line, the coolant comprising a brine, the brine being an aqueous mixture which lowers a freezing point of water.
