Gas Desulphurisation Systems

The most efficient alternative to activated carbon

The UGN® systems are made for external biological-chemical final desulphurisation of undried biogas. Over many years, this method has been proven to reduce high hydrogen sulphide loads down to <1 ppm at a reasonable price.

The biological efficiency of these systems is adapted to the microbiological properties (H2S concentration, humidity, temperature).

The desulphurisation system is set up outside the digester to facilitate regulating and maintenance without interfering with the processes running inside the digester.

Another advantage: The biogas does not have to be dried before being fed into the desulphurisation system, which cuts down on operating costs. Furthermore, the filtering material has a structure that allows perfect pouring, thereby doing away with extra compressors.

Our desulphurisation systems are based on the UgnCleanPellets® S 3.5 filtering material by default.

Your benefits at a glance


  • Low operating costs (no drying of gas, no compressor needed)
  • Targeted and complete removal of H2S concentrations of up to 100,000 ppm
  • Guaranteed desulphurisation of process-related H2S peaks
  • No corrosion
  • No chemicals handling
  • Involves no elements that are hazardous to water
  • Amortisation within 2 – 3 years compared with other desulphurisation methods


  • Biogenic fuel gas
    → Including biogas, fermentation gas, landfill gas, pyrolysis gas, sewer gas
  • Geogenic gas
    → Geothermics, deep drilling, mining
  • Gas from industrial production processes
    → Exhaust air from production, oil mills, pyrolysis, coking plants, blast furnaces
  • Energetic gas
    → Including natural gas, accompanying gases of petroleum, lean gas, sour gas, synthesis gas, gas from petrochemical applications

UGN® BEKOM H system

Raw biogas treatment for later use in CHP applications

  • UgnCleanPellets® S 3.5 filtering material
  • Biogas module(s) made of plastic material or stainless steel


  • The BEKOM H gas desulphurisation system is based on the UgnCleanPellets® S 3.5 filtering material and combines chemical and biological reactions.

The untreated, warm and humid biogas flows through the filter module that is filled with UgnCleanPellets®. The hydrogen sulphide is targeted and completely removed from the raw gas and transformed to elemental sulphur.

Atmospheric oxygen is fed in to allow the filtering material to self-regenerate, while the desulphurisation process is running at the same time. This ensures that the desulphurising capacity of the material is maintained for a long time. When the pellets reach their maximum take-up capacity, the hydrogen sulphide content in the clean gas increases gradually.
