Patent number: 11397049Abstract: A purification system for recovering carbon dioxide from a gaseous carbon dioxide stream originating from a fermentation process, brewery or a bottling line is provided. The purification system includes a compressor in fluid communication with an absorber. The compressor provides a compressed gaseous stream at a predetermined pressure and the absorber separates the compressed gaseous stream into a carbon dioxide rich gaseous stream and a contaminant rich stream. A condenser is designed to operate at a pressure of at least 30 bar and is designed to separate the carbon dioxide rich gaseous stream into a condensate and a purge gas. A distillation column is configured to separate the condensate into a second purge gas and a purified carbon dioxide stream.Type: GrantFiled: December 22, 2017Date of Patent: July 26, 2022Assignee: UNION ENGINEERING A/SInventors: Rasmus Find, Jan Flensted Poulsen
