Siloxanes in Biogas and Landfill Gas - The Benefits of GC-MS Analysis for CHP Gas Processes
Feedstock for biogas and landfill gas (LFG) production often contains siloxanes; silicon-based organic materials. When combusted in combined heat and power (CHP) gas engines, siloxanes form silicon dioxide, an abrasive glass-like material which damages the engines.
We have recently published a paper on how Gas Chromatography-Mass Spectroscopy (GC-MS) can provide:
- Quantitative analysis of the gas for the concentrations of the individual compounds
- Spectral confirmation of the identity of the compound
- Qualitative analysis of the samples over a number of time periods to show the total organic compounds breaking through the filter media
- Quantitation of the total volatile organic compound (VOC) content of the gas post filter.
Through identifying the concentration and profile of siloxanes and other components/compounds within biogas and LFG, GC-MS can provide useful information about the contamination levels on the filter media and potentially provide earlier notification of when the siloxanes will ‘breakthrough’ the filter media.
