Preparatory Measures for Biomethanation
Production of a constant gas composition with the application of a
broad input spectrum by
-
successive loading of the dry fermenters
-
Substrate supply in wet fermentation via storage tanks
-
Production of mixed gas in differing gas storages
Elimination of trace elements from biogas by
-
Desulfurization
-
physical-chemical gas scrubbing

Measures for Gas Scrubbing
Air lance
Desulfurization in the gas storage
External gas scrubbing

Conclusion
The biogas plant in Halle-Lochau is well
prepared for the production of
biomethane from biogas.
