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.
