LIQUID CO2 FROM BIOGAS

Pentair’s CO2Bolt-On is the proper installation to create green liquid CO2 from a renewable, cost-efficient source: upgraded biogas.

The biogas upgrading process vents a waste stream which is a highly concentrated flow of CO2, with a limited amount of methane and other contaminants, creating the ideal source for cost-efficient production of liquid CO2. Additionally, the methane slip can be eliminated, creating a higher bio-methane yield for your biogas upgrading installation. The renewable CO2 can be used in industrial (technical) CO2 applications (CCS/CCUS to industrial use) or as an ingredient for the food and beverage industry (food-grade CO2).

With 75+ years of experience in CO2 equipment and extensive knowledge of CO2 recovery systems, CO2 users are assured the CO2 product from Pentair’s systems fulfills market specifications. Customers can confidently rely on the supply of quality liquid CO2 from a known source.


WHY PENTAIR?
Pentair’s Sustainable Gas Solutions specializes in biogas upgrading and CO2 recovery systems. With over 1500 installed plants, including more than 40 biogas upgrading systems, Pentair’s dedication to this core business is widely recognized within the industry. Our R&D department is constantly researching emerging technologies for improving the efficiency and effectiveness of our biogas upgrading solutions. Most importantly: we are there for you when your system is operating -- with global service hubs and dedicated technical support. We diagnose and optimize whenever you need us to keep your plant up and running! That’s why Pentair!


Benefits

  • Decarbonisation, direct production of CO2 can lead to a negative carbon footprint and lower carbon intensity scores (CI) 
  • No methane-slip: the off-gas can be brought back to the inlet of the biogas upgrading unit, thus increasing the production yield of methane to 100% 
  • Highest uptime availability through a robust design and dedicated service team (24/7 Technical service) 
  • Independent, simple and compact: design allows for reduced installation costs and the option to operate your upgrading system independently from the CO2 system 
  • Liquid CO2 quality exceeds global standards to be sold as technical CO2 or (when certified) as food-grade CO2

PROCESS DESCRIPTION

Exhaust CO2 from the biogas upgrading unit is fed to the bolt-on system, where CO2 compressor units increase the gas pressure to 18barg (261psig) in two stages removing condensate in the process. Next, trace impurities and moisture are removed. The purified CO2 gas is led into the cooling system where the CO2 is liquefied. The off-gas containing all non-condensable gases (CH4, O2, N2) is purged as off-gas and can be brought back to the inlet of the upgrading unit. The purified liquid CO2 end product is fed at 17.5 barg (218 psig) to the onsite storage tank.
