Activated carbon filter

Desulphurisation using activated carbon filters is necessary to prevent corrosion. Sulphur occurs as hydrogen sulphide (H2S) in biogas, the combustion of which would produce aggressive sulphuric acid (H2SO4). The hydrogen sulphide content is usually low, but can rise rapidly with protein-rich substrates (grain, legumes, slaughterhouse waste and the like), resulting in so-called sulphur peaks.

Our 3-chamber activated carbon filter is designed in such a way that it can capture sulphur peaks, thus ensuring that no unpurified biogas leaves the filter at any time. At the same time, the patented 3-chamber system guarantees maximum utilisation of the activated carbon - activated carbon filter for biogas

Customised solutions can also be produced as an alternative to the 3-chamber system.

 

This is what characterises all our 3-chamber activated carbon filters:

• Low operating costs thanks to optimum utilisation of the activated carbon with maximum safety against H2S breakthrough, even during sulphur peaks
• Pressure stability even in high heat up to -30/+50 optionally +/- 200 mBar
• Long service life thanks to high-quality stainless steel construction 1.4571 (V4A)
• Quick-change system for the filter unit without direct contact with the activated carbon
• Each unit thermally insulated as standard
• Can be integrated into any system concept thanks to modular design
• Optional non-stop/maintenance module enables low motor downtimes

 

All activated charcoal filters also available as:

• Multi-chamber filters (individual number of chambers possible)
• Continuous-flow filter (mounted activated carbon filter
