Basics
- This page aims to cover the issue of Hydrogen Sulfide ( H2S ) in the Biogas produced by Aerobic Digestion
- Some discussion on how this impacts Biogas use / Biogas Upgrading , or Occupational Safety / Confined Space Entry procedures and such will be done, but refer to those pages for more thorough discussion of that
Origin and Destinations
- Total Sulfur
- Then via the Sulfur Cycle it will either end up in:
- The Biogas (As H2S
- The Digestate (As Insoluable Precipitates
- Tank/Pipe Fouling due to this may be a concern as well
- Or in the Anaerobic Digestion Effluent as Soluble Compounds, Organic Sulfur, or Suspended Insoluble Compounts/H2S
Quantification
- Quantification of H2S in Biogas
- Or potentially inference of this via “burn rate” of Steel Wool/Iron Filings Reactants, or Removal Rate of Elemental Sulfur/Sulfuric Acid in a Biogas Upgrader
- Quantification of the Anaerobic Digestion Effluent
- Via Liquid Chromatography–Mass Spectrometry ?
- May also be able to Centrifuge Solids out, then be able to distinguish between liquid effluent and effluent-suspended solids
- Quantification of Digestate Composition
- Matrix-Assisted Laser Desorption/Ionization ?
- Alternatively Doing LC-MS of Various Solvent-Sample Solutions?
- Inductively Coupled Plasma Atomic Emission Spectroscopy ?
- The latter two seem rather intensive, so may be a matter of sending samples to an off-site lab on occasion
- The former may be more easily adapted to a plant’s in-house operations
