Reactant binds hydrogen sulfide
Hydrogen sulfide (H2S) is an undesired component of biogas. In addition to acidifying the oil of engines in cogeneration systems, a large number of corrosion symptoms in biogas plants are due to the action of H2S. In high concentrations, hydrogen sulfide also has a toxic effect on methane-forming microorganisms.
By developing the extensively tried and tested reactant FerroSorp® DG, HeGo Biotec GmbH has been able to provide owners of biofermentation plants with a safe and cost-effective product to bind hydrogen sulfide in the fermentation reactor.
The 45 employees of Produktions- und Umweltservice GmbH in Lauta produce FerroSorp® DG from ferric hydroxide, exclusively for HeGo Biotec GmbH.
The reactant, a harmless powder, is easy to handle and to store.
The addition of FerroSorp® DG binds hydrogen sulfide in the fermentation reactor and converts it chemically in such a way that the formation of methane is not inhibited. H2S-related corrosion problems are also reliably prevented. The availability of micronutrients is improved and the biological process stabilised.
