Biogas Upgrading

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 bio CO2  

Airco Process Technology – Obviously Green

Airco’s new upgrading solution for biogas plants is a full electrical solution that converts approx. 99,9% of the biogas to biomethane.

Airco’s 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.

Looking for a way to significantly reduce methane slip and improve the overall performance of your water scrubber-based biogas upgrading plant? Look no further than our SlipRec unit!

When biogas from ADs is split into Methane and Carbon Dioxide in a Biogas Upgrading plant, normally only the Methane is utilized. It is however relatively easy also to capture and utilize the Bio CO2, offering a second value stream.

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.

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 Power-to-X technologies, there will be a very substantial need for CO2  from green sources, such as biogas.

Biomethane from our upgraders can also be liquefied (as CBG or LBG) and can for instance be used in the transportation sector (trucks, heavy machinery, ships).
