Ammonia removal from Biogas
Ammonia (NH3) is a by-product of the decomposition of proteins associated with anaerobic digestion. Ammonia must be removed from the biogas, so as:
-
- to protect against corrosion and to maintain plant integrity
- to protect catalysts and membranes
- to optimize the combustion process by maintaining a high calorific value and high density of the treated biogas
- to avoid odor emissions (e.g. when treating digestate)
- to eliminate health hazards to humans

AddSorb™
Our AddSorb™ VB-series product line helps to mitigate these risks by selectively removing ammonia from biogas streams. By effectively removing this contaminant, AddSorb™ VB-series products help protect people and equipment, reduce emissions, optimize energy production, improve process efficiency and increase safety in biogas production facilities.Product Name | Form | Characteristics |
---|---|---|
AddSorb™ VB1-BG | Granular / Pellets | Acid impregnation |
AddSorb™ AM25 | Granular only | Coconut based, acid impregnation, enhanced capacity |
EcoFlow™
Jacobi’s EcoFlow™ mobile filter range are usually installed before the water condenser in the biogas purification process.
Jacobi has a full range of mobile filters for flow rates between 75 and 4,000 m³/h biogas per filter. Our wide range of rental EcoFlow™ filters are offered via local sales offices, avoiding international transport.

Auxiliary equipment and additional services
In addition to mobile filters and different media, Jacobi Services also offers various items of auxiliary equipment and additional services for hydrogen sulphide (H₂S) removal from biogas, including:- Selection of the type and number of EcoFlow™ filters. The selection depends on the flowrate and the estimated annual activated carbon consumption.
- A series of removable insulation jackets to prevent condensation of water and to keep the relative humidity within an acceptable range for EcoFlow™ mobile filters.
- The capabilities of the Jacobi France laboratory for externally accredited self-ignition testing of virgin or spent activated carbon.
Recycling and reactivation
Depending on the region and the composition of the spent carbon, different recycling or disposal routes are possible. Impregnated spent activated carbons are currently not recyclable.
