More Than 99%
Ammongas uses the proven absorber stripper system with amines for upgrading biogas. The process has been used for many years in the oil and gas industry for removal of CO₂, H₂S other acidic gases, and is known for being a robust and reliable system.
By separating and removing the CO₂, raw biogas is efficiently upgraded to high-purity biomethane. Our advanced absorption process is exceptionally efficient, with the ability to limit methane slip below 0.05% – resulting in a methane recovery rate exceeding 99.95%.
Furthermore, Ammongas’ amine upgrading can remove down to less than 50 ppm of CO₂ in the biomethane stream, and thereby prepare the gas for liquefaction.
Our reliable technology ensures low operational costs and an average uptime of 99%, including comprehensive service support.

Large savings
A pressureless upgrading process saves a lot of costs in the building phase and less expenses in maintenance.
A long life
The parts in an upgrading plant from Ammongas are robust and of high quality, which ensures a long life.
20+ years
We have built facilities for over 20 years across the Nordics, and have also branched out to other markets.
More than 50%
The share of biomethane in the Danish gas system is approximately 40%. More than half of that is processed by an Ammongas upgrade plant.

Increase Your Production With New Efficiencies
Do you want to significantly reduce your operating costs and/or explore at the possibilities for capacity expansion at your plant?
At Ammongas, we offer several tools to identify opportunities for improvements and/or expansions. Our latest case led to the following results:
✓ Improve heat consumption by 10–20%
✓ Increase capacity by 10–30%
These improvements were made by carefully increasing column capacity and enabling higher absorption rates.
