Pollution Prevention Opportunities for Ammonia Emissions in the Food and Beverage Sector

The University of Wisconsin-Madison (UW-Madison) covered their recently completed food and beverage pollution prevention (P2) work funded under EPA Region 5’s Pollution Prevention Grant Program. The webinar provided attendees with: 1) an overview of the sources of emissions of ammonia from the industrial refrigeration systems commonly used in food and beverage processing facilities; 2) a summary of refrigerant inventory determination methods for industrial ammonia systems, including an Ammonia Inventory Calculator, which is a new online resource to estimate the operating charge of existing systems; and 3) the use of dynamic charge calculations for flagging refrigerant losses from systems that would otherwise go undetected. Applications of these methods, along with best practices for identifying and eliminating fugitive ammonia leaks identified during field work in Wisconsin food and beverage plants were also discussed.

Speakers:

  • Douglas Reindl, Ph.D., P.E., Professor UW-Madison & Director of the Industrial Refrigeration Consortium
  • Marc Claas, Researcher, UW-Madison’s Industrial Refrigeration Consortium
