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...
Nitrogen as a sealing gas to prevent explosions. Turbo compressors are used to compress large gas flows. They are used in petrochemical plants and refineries, for example. In this context, their task is to increase the pressure in gas pipelines. Nitrogen can be used as a sealing gas in turbo compressors. It is used to blanket the mechanical seal, which seals the rotating shafts against the machine housing. This prevents the process gas from penetrating the engine and prevents any ignition of the gas.
