Upgrading of biogas in a class of its own with Ammongas

More than 99%

Ammongas uses the well-known absorber-stripper system with amine 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.

Ammongas’ absorption process is so efficient that the methane slip to the atmosphere can be reduced to less than 0.05%. This means that the amount of methane gained is more than 99.95%.

Due to the efficient process, a high concentration of 99% of methane in the separated biomethane stream can be achieved. 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.

The robust technology results in low operational expenses and an average up-time of 99% including service.
