2017 Master Brewers Conference
54. Sustainable gas recovery solutions for brewers—Biomethane and green CO2

Jeff Tocio, Pentair, Delavan, WI, U.S.A.

Saturday, October 14
8:30–10:15 a.m.

Carbon dioxide recovered from brewery fermentation is a well-established practice for brewers to have their own ready supply of green CO2 produced on site for use in the brewery. In addition, in some cases where high strength waste is treated in anaerobic digesters, the biogas from the digester can be recovered and converted into two value streams: additional green CO2 for use in the brewery and biomethane of natural gas or vehicle quality. Through the application of membrane and cryogenic technology, 100% CH4 can be recovered with minimal CO2 emission. The high-caloric biomethane is either buffered (in the national gas grid) or consumed on site (boiler fed with clean high calorific gas for optimal efficiency). The purified CO2 is ready for food/beverage grade applications. An overall benefit of the combined approach is a reduction in the overall carbon emissions from the brewery site and a dual value stream that includes green CO2. This presentation will discuss the technology, process, costs, and benefits. References of current installations will also be given.
