Removing hydrogen sulfide (H₂S) is one of the most critical steps in biogas treatment. This compound is highly corrosive and can damage equipment, reduce energy efficiency, and affect gas quality. Having a reliable and safe desulfurization method is therefore essential for any biogas plant.
At PROMINDSA, we have developed MICRONOX ON16, a natural product based on iron oxides and hydroxides, designed to capture H₂S directly inside the digester. Its formulation provides a clean, safe, and effective alternative to chemical or biological systems.
Why remove H₂S from biogas?
H₂S is produced during anaerobic digestion, mainly from the degradation of sulfur-containing compounds. If not removed, it can cause:
- Corrosion in engines, pipes, and metallic components.
- Lower energy efficiency of the biogas.
- Safety hazards due to its toxicity.
- Harmful emissions into the environment.
Reducing its concentration not only protects equipment but also improves gas quality and enhances process profitability.
MICRONOX ON16: natural technology for a safer process
MICRONOX ON16 is added directly into the digester, where it reacts with H₂S to form iron sulfide and elemental sulfur. This reaction occurs without the need for oxygen injection or hazardous chemicals, making handling simpler and safer.
Key technical advantages
- No explosion risk: no oxygen injection required.
- Safer and cleaner: no toxic or corrosive by-products generated.
- Consistent efficiency: improves digester stability and biogas quality.
- Added value: reaction products enrich the digestate, promoting circular economy.
- Easy application: available in water-soluble bags or big bags for direct dosing.
Sustainability and circular economy
MICRONOX ON16 proves that natural mining resources can also deliver technological solutions. Its natural iron oxide base transforms a harmful by-product (H₂S) into a valuable material for agriculture, closing the material loop and promoting circular economy principles.
A product aligned with the energy challenges of the future
As biogas plants continue to expand, the need for safer, cost-effective, and sustainable treatment systems grows. MICRONOX ON16 stands out as an efficient solution for operators aiming to maximize gas production without compromising safety or environmental performance.
