Coors brewing CO2 extract system

Maintaining CO2 limits below legal levels for major brewer

The Outcomes:

  • CO2 levels maintained within acceptable limits
  • Low energy solution
  • Low noise solution to comply with very low boundary noise limitations
  • Original process operation unaffected

The Challenge:

Carbon dioxide (CO2) levels were intermittently exceeding legal limits and tripping our client’s gas detection system in the process area, regularly disrupting the production process and endangering the health of staff members.

The Solution:

The source of the problem was traced to a number of specific tank vents. The discharge points of these vents were rerouted to a common point, where possible, without affecting their function.

A local capture system was designed to retain the CO2 but allow the product to escape, and a low air volume exhaust was installed.
