Odour
Weak (fuel gases are odorized)
Abatement
Oxidation / adsorption
Toxicity
low (chemical)
Flammability
very high
Chronic risk
minimal
Environmental
GHG / ozone precursor
| Aspect | Detail |
|---|---|
| Scrubbing suitability | Poor with water due to non-polarity and very low solubility. |
| LEL–UEL (indicative) | ~0.5–2.2% LEL / ~7–15% UEL (species-dependent). |
| Buoyancy | Methane lighter than air (accumulates high); C₃+ heavier (accumulates low). |
| Alternatives | Thermal/catalytic oxidation, recovery/recirculation, or activated carbon for low flows. |
