Summary

IT IS BECOMING AN INCREASING PRACTICE TO PLACE ALL STAGES OF BRIGHT BEER BREWING UNDER INERT GAS CONDITIONS TO PREVENT OXYGEN ABSORPTION BY THE BEER WITH SUBSEQUENT OXIDATION FLAVOURING. CO2 OR N2 CAN BE USED, ALTHOUGH N2 IS NOT SO ACCEPTABLE IN THE END PRODUCT. THE AUTHORS POINT OUT THAT MANY BREWERIES HAVE PLANTS THAT RECOVER CO2 FROM FERMENTATION PROCESSES AND IF THIS IS DONE EFFECTIVELY AND CO2 FROM INERT GAS USE IS ALSO RECOVERED, A BREWERY CAN BE SELF-SUPPORTING IN CO2. THE CO2 RECOVERY PROCESS CAN BE MORE ENERGY EFFICIENT IF AN ENERGY EXCHANGE IS INCORPORATED BETWEEN THE VAPOURIZATION OF STORED CO2 FOR FEED TO PROCESS VESSELS, AND THE CONDENSATION OF RECOVERED VAPOUR AFTER IT HAS BEEN COMPRESSED TO SUITABLE PRESSURES. NORMALLY THE CONDENSATION IS CARRIED OUT BY A SEPARATE R22 OR SIMILAR SYSTEM. SAVINGS OF UP TO 25% ARE CLAIMED IN RUNNING COSTS. D.W.H.
