Reducing Hydrogen Sulfide (H2S) is a Critical Step in Turning Livestock Waste into Biogas
Dairy, beef, swine, and poultry manure all release methane into the atmosphere once expelled. Methane gas can be captured during the process of anaerobic digestion, where microbes break down the raw material into fatty acids. The fatty acids are further broken down by special bacteria, called methane formers, and convert the acids to methane gas and carbon dioxide. However, the methane gas cannot be used immediately after digestion because it contains trace contaminants – one of them being hydrogen sulfide. To transform the gas from livestock waste into a useable form of biogas, H2S must be removed.
Our FerroSorp® media will remove your H2S and save your company time and money.
We Achieve the Highest Loading Rates:
FerroSorp® has a chemical makeup that not only captures H2S, with a small amount of oxygen it will regenerate to continue to convert the captured H2S to elemental sulfur. The sulfur is captured on the inside pores of the FerroSorp, so the pressure drop is lower than with other solutions; therefore, decreasing parasitic loads on pumps.
The removal of H2S from a gas stream can be described through the following chemical reactions:
- Adsorption: 2 Fe(OH)3 + 3 H2S → Fe2S3 + 6 H2O
- Regeneration: Fe2S3 + 1½ O2 + 3 H2O → 2 Fe(OH)3 + 3 S
