Powdery ferric compounds for biogas process desulphurisation

Abstract: Desulphurisation strategies are essential for biogas plants, since high hydrogen sulphide concentrations significantly reduce the biogas quality. Internal chemical desulphurisation using ferric compounds provides advantages regarding substrate-dependent dosage as well as prevention of process imbalance and corrosive damages within gas-transporting components of the biogas plant. Up to now, the usage of ferric compounds is based only on the iron content, whereas chemical and physical properties are not taken into consideration. To cope with this problem, powdery ferric compounds of different chemical composition and grain size were compared by studying their influence in dependence of process parameters like hydrodynamics or hydraulic retention time using laboratory scale biogas reactors. The presented results enable specific recommendations regarding which type of ferric compound is advantageous to provide an optimal desulphurisation effect depending on the plant specific process p.... https://www.landtechnik-online.eu/landtechnik/article/view/28
