Technology Description:

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.  

Interra Global's FerroSorp® media will remove H2S and save time and money in the process.  

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

Technology Strengths, Weaknesses and Critical Indicators

NOTE: There are multiple technologies that are used as part of integrated manure management systems and yet are not manure management types on their own. The impact of these technologies on their own would be minimal or very difficult to quantify.

General Support & Other:

  • Can be an integral part of many manure management systems
  • Most projects have at least some equipment that supports operations of the main technology
  • This technology is not evaluated on its own, the NEAT Matrix for this technology is neutral unless utilized with other technologies.

Newtrient Comments/Opinions:

Interra Global has recently been added to the technology catalog, Newtrient will continue to work with them to further refine the cost and performance information, publishing it and updating the 9-Point score as information becomes available and as new commercial dairy installations come online.
