Biogas is a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Initially the organic matter is placed into sealed tanks known as digesters. Naturally occurring micro-organisms digest (breakdown) the organic material, releasing a gases including methane and carbon dioxide. The remaining solids are rich in nutrients and is often used to make fertiliser. Many forms of biomass are suitable for anaerobic digestion, including: food waste: farm slurry and manure, as well as crops and crop residues. The initial biogas may have a large array of minor constituents which are seen as unwanted contaminants and need to be removed before use. The biogas is often further treated to produce relatively pure methane often called biomethane. The purified biomethane can now be injected into the UK gas grid network or used to fuel vehicles.
Biogas and Biomethane Analysis
To ensure the quality of biogas and biomethane detailed analysis is often required. We provide a full sampling and analysis service for many of those tricky to test components including:
- Methane, Carbon Dioxide, Oxygen and Hydrogen
- Hydrogen Sulphide
- Total Sulphur
- Organic Halides
- Hydrogen Fluoride
- Hydrogen Chloride
- Siloxanes
- Arsenic
- Mercury
- Ammonia
- Volatile Organic Compounds including Terpenes, Aldehydes, Ketones, Xylene and Alcohols
- Micro organisms
- Water Dewpoint
- Hydrocarbon Dewpoint
