Biogas Upgrading
Upgraded biogas, also referred to as biomethane or Renewable Natural Gas (RNG), is a crucial, commercially proven, and rapidly growing technology that contributes to energy resilience and replacement of fossil fuels.
What we do
We have developed next-generation of water- and amine-based biogas upgraders that enable biogas plants to be operated more efficiently and with the option of converting the biogas stream not only into natural gas grid specification methane but also into high-value products such as liquid biomethane and biogenic-CO₂.
We are one of few that delivers both water- and amine-based biogas upgrading solutions. And we are constantly expanding our portfolio with new technologies. At the moment, we have numerous patent-pending biogas upgrading technologies including our trademarked SlipRec™ solution that significantly reduces methane slip on water-based upgraders.
See our solutions below
Amine based
Range: 1000 – 10.000 Nm3
Heat: 500-700 W/Nm3
Power Consumption: 100-130 W/Nm3
Water consumption: 0-2 L/Nm3 biogas
Heat recovery: Up to 80-90%
Our amine biogas upgraders are the most advanced and efficient way to upgrade biogas to biomethane. With a capture rate of 99.9%, our solution ensures that your plant can produce the highest quality biomethane possible
Water based
Range: 1000 – 10.000 Nm3
Heat: 0
Power Consumption: 200-300 W/Nm3 biogas
Water: 0-5 L/Nm3 biogas
Our new upgrading solution for biogas plants is a full electrical solution that converts approx. 99,9% of the biogas to biomethane.
Why upgrade Biogas?
In most cases upgrading biogas to biomethane for the natural gas grid is the most financially attractive option for biogas plant owners.
Biomethane from our upgraders can also be used as CBG or liquefied to Bio-LNG (LBG) and can, for instance, be used in the transportation sector (trucks, heavy machinery, ships).
In addition to the methane stream, there is a significant CO₂ stream from biogas upgraders. Traditionally this has been viewed as a potential liability, but with the current investments in CCS and CCU, including Power-to-X technologies, there will be a substantial need for CO₂ from green sources such as biogas.
We can deliver the full gas package for both green- and brown field projects:
As one of few suppliers Airco´s broad process know-how and experience allow us to help biogas customers with a full gas-package treating all value streams starting from upgrading of the raw biogas to biomethane, purification and liquefaction of the separated CO₂ and when needed liquefaction of the biomethane into Bio-LNG. All in one fully automated and integrated solution.
