Oxygen for the desulphurisation of biogas plants

In biogas plants, biogas is produced from biomass via the fermentation process. This is used to generate power or heat. The microbial degradation of plants, slurry or slaughter residues takes place in the absence of oxygen. However, different types of biomass have a very high sulphur content. This is later contained in the biogas as hydrogen sulphide (H2S). Together with any water present in the biomass, H2S forms an acidic and corrosive mixture called alkali sulphide. Alkali sulphide can cause serious damage to metal, wood and concrete parts of the fermenter and the pipelines.

Oxygen is used to desulphurise the biogas plant. The targeted and accurately dosed addition of oxygen in the fermenter promotes bacteria development. The bacteria gained in this way decompose the hydrogen sulphide microbially and, in doing so, help to prevent damage.

With our oxygen generators, we supply high quality solutions for the stationary and mobile production of oxygen for different applications, including for low volume requirements.
