ROTARIA Biogas pre- and exhaust gas treatment


The installation of a ROTARIA activated carbon filter will result in a fine desulphurization of the biogas. Cleaning the biogas reduces engine wear and raises the working life of the engine oil. In addition, the installation of an activated carbon filter prepares the engine for the operation of an exhaust catalyst. These catalysts are necessary for staying within the limit values for formaldehyde emissions. The ROTARIA activated carbon and catalyst systems can also be installed at existing plants.
Fine desulphurization by activated carbon:
  • Low invest cost
  • Protection of catalyst
  • Longer working life of engine oil
  • Lower maintenance cost
  • Prolonged working life of the CHP engine
  • Low pressure losses < 1 mbar
  • Simple to install
  • Easy exchange of activated carbon
