IRON CHELATE – BIOGAS DESULPHURIZATION

Many biogas plants have problems with sulphur and hydrogen sulphide  in the biogas cycle. In addition to individual advice, we also offer the new desulfurization form with SHIEER IRON CHELATE.

An increased content of hydrogen sulphide in the biogas causes the acidification of the engine oil and destroys through corrosion the engine, the pipes and the building substance of the biogas plants. In addition, the hydrogen sulphide in the fermenter, as a cell cytotoxine directly inhibits the microbiology. The iron chelate already reduces sulphur in the fermentation substrate and thus reliably prevents the formation of hydrogen sulphide.

Iron is one of the most important trace elements for bacteria and is often limiting. The iron in the iron chelate is 100% available to bacteria.

The iron is present in the iron chelate as a metal complex. As a result, it can absorb electrons and make them available for bacteria that form methane (reducer). This increases the formation of methane. The iron chelate is regenerated by forming these metal complexes. Therefore, the required amount can be much lower than with conventional iron preparations.

PRODUCT INFORMATION SHIEER EISENCHELAT

Composition:
Complex bound iron, secondary plant substances

Specific waight:
1,4 kg/litres

Benefits:

  • Reduction of sulphur in the fermentation substrate
  • Reliable prevention of the formation of hydrogen sulphide
  • 100% bacteria available and therefore an important nutrient
  • As an oxidizer / reducer, ensures that electrons become available for the formation of methane
  • Liquid, thus easy dosage (automatic dosage possible)
  • Pollutant content / heavy metal entry significantly lower than iron (III) hydroxide
  • Completely water-soluble (no deposits on the bottom of the fermenter – no reduction in foul space – no reduction in residence times)
  • Shieer Iron chelate is not corrosive, therefore gentle on materials (longer life of the agitators)
  • No dust load (important for occupational safety)

Dosage and application

100 ml SHIEER iron chelate per 50 kW electrical power (daily). Preferably enter directly into the fermenter via the substrate. Optionally, it can also be added to the storage tanks (condition: mass must often be stirred).
