Emission abatement systems for gas-fired plants
The main pollutants emitted from gas-fired engines include:
- Nitrogen Oxides (NOx)
- Carbon-monoxide (CO)
- Unburned hydro-carbons (UHC). Emission of SO2 and Particulate Matter from gas engines is negligible.
Gas engines, in particular lean-burn engines, can most often comply with German TA-Luft regulations without secondary abatement both with or without an oxidation catalyst to reduce CO and UHC. No reactants or residuals are involved.
