Frontpage Application Note Self-Sufficient CO2 Production
Fermentation CO2 can be stored and used in carbonation for self-sufficiency. The required quality was obtained through in-line control with the O2 sensor InPro6950i G. As a result a considerable cost saving was achieved.
 
To buy or to produce requested CO2
Breweries, soft drink producers and other segments of the Food and Beverage industry use carbon dioxide (CO2) in their production process. But in the brewing industry CO2 is a byproduct of the brewing fermentation process that is used to protect and ensure the quality and uniformity of beer. CO2 is used to displace air from tanks, cans, bottles, and kegs before they are filled with beer.
 
In many cases, CO2 is also incorporated directly into the product. In these applications either recovered or purchased commercial CO2 is used.
 
Self-sufficient CO2 production
In many breweries there is a desire to become or remain self-sufficient in their CO2 production for use in their processes. To be self-sufficient a brewery must be able to produce enough CO2 and have the storage capabilities to meet the demands throughout the entire production process. They must also balance the cost of purchasing CO2 with the cost of the ...
