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

- 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

Our desulphurisation system
UGN® BEKOM H system
SCOPE OF APPLICATION
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
THEORY OF OPERATION
- 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.
