CO₂ Recovery for Large Breweries
For large regional breweries producing 300,000 to 500,000 hectoliters per year, Haffmans CO₂ Recovery Plant (CRU) transforms fermentation gas into high-quality CO₂ for reuse in production. This solution ensures independence from external suppliers, compliance with ISBT standards, and a smaller carbon footprint.
Benefits
- Achieve CO₂ self-sufficiency and operational independence.
- High quality liquid CO2 ≥ 99.998 % v/v, O2 ≤ 5ppm v/v.
- High recovery efficiency even at low CO2 inlet purity with ≥ 95% v/v.
- Robust design for reliable 24/7 operation, uptime ≥ 95%.
- Flexible, modular setup to meet the site’s layout needs.
- Natural refrigerants CO2 (R744) and NH3 (R717) applied.
- Early recovery and up to 60 % energy savings with LiquiVap (optional).
- Access to CO2 know-how and technical support.

Functional Description
-
- Raw foam-free fermentation gas is fed to the plant, where it is buffered in a balloon (1) and scrubbed of water-soluble contaminants such as ethanol in the gas washer (2).
- A 2-stage dry running CO2 compressor unit (3) increases the gas pressure to 18barg (261psig), removing condensate in the process. The remainder of the impurities and water are then removed in the dual activated carbon filter and drier unit (4).
- Regeneration of this unit is automatic, utilizing heating elements and dry CO22 purge gas. CO2 liquefaction takes place in a refrigerant-cooled condenser (6), which includes a refrigerant condenser (7) and a refrigerant compressor (8). O2 is removed in the stripper (5).
- The purified liquid CO2 end product is transferred to the onsite storage tank.
- Raw foam-free fermentation gas is fed to the plant, where it is buffered in a balloon (1) and scrubbed of water-soluble contaminants such as ethanol in the gas washer (2).
