OXYGEN GENERATOR IS USED FOR DESULFURIZATION IN A BIOGAS PLANT

A 10 'container is leaving our factory this week. The container includes a PO 2150 OnTouch oxygen generator. The oxygen produced is pumped into a biogas plant to prevent damage to the resulting alkali sulfide on the structure.

Sustainable energy generation is becoming increasingly important. The production of biogas plays an important role here. In biogas plants, the gas is obtained from the fermentation process from biomass. Ultimately, biogas is used to generate electricity or heat. More and more communities in the UK are also using regional energy production facilities. Plants, manure or slaughtering residues are introduced into the biogas reactor. These serve as a nutrient for microorganisms. The microbial degradation of these substrates, which takes place in the absence of oxygen, results in metabolic waste in the form of gas. However, since the biomass usually has a high sulfur content, hydrogen sulfide (H2S) is later contained in the biogas. Together with the water present in the system, this forms alkali sulfide, an acidic and corrosive mixture. This can cause great damage to metal, wood and concrete parts of the fermenter and the pipes.

To avoid this, oxygen is introduced into the biogas reactor. The INMATEC oxygen generator produces 6 m3 of oxygen per hour on site in a container. The oxygen generated here is used to desulfurize the biogas plant. The addition of oxygen in the biogas reactor promotes the development of bacteria that microbially decompose the hydrogen sulfide and help prevent damage.
