Energy Efficiency Improvement and Cost Saving Opportunities for Breweries
carbon dioxide recovery systems In the fermentation process, the yeast feeds on the wort to produce carbon dioxide and alcohol. This carbon dioxide can be recovered with closed fermentation tanks and used later in the carbonation process. The fermentation process generates about 8-10 lbs/barrel wort (3-4 kg CO2/hl) (Lom and Associates, 1998). Typical CO2 scrubber operations require 2 kg of water per kg of carbon dioxide (Dell, 2001). A large brewery can become self-sufficient for CO2 if a well-d
