Desulphurization plants are primarily used for removal of sulphur (H2S) from biogas. Sulphur in biogas causes environmental pollution and serious corrossion problems in pipe systems, heaters and gasmotors.
The H2S impregnated gas is passed through a tower formed desulphurization reactor containing specially formed gascleaning mass (medium) in pellet form. This leads to a chemical reaction between the sulphur in gas and cleaning medium containing ironoxide; the interaction results in the chemical absorption of sulphur into the cleaning medium, ironoxide becomes ironsulphide. The controlled addition of compressed air into the crudegas causes a constant regeneration of the cleaning medium as elementary sulphur forms.
