Activated carbon filters
ENSPAR offers activated carbon filters to reduce H2S and siloxane in raw biogas. They have a modular structure with 1 to 3 chambers. The gas connections are usually in NW 160, the lateral in-feed nozzles in NW 250, and the inspection apertures for used carbon in NW 400. The diameter is approx. 1.00 m and the height up to approx. 3.50 m. ENSPAR provides filters for biogas flow rates of ~50–500m³.
ENSPAR offers gas drying units to dry raw biogas. Gas drying units cool the raw biogas and extract the condensation in a controlled environment. The gas drying unit is integrated in the gas lines and is intended for outside assembly.
For desulphurization with oxygen, ENSPAR offers prefabricated compact desulphurisation units with individually adapted pumps.
