SO₂ removal efficiency in processes using Flue-gas desulfurization FGD / DeSOx

Combustion is often a dirty process, releasing a range of pollutants including sulfur dioxide, nitrogen oxides, carbon dioxide, volatile organic compounds, fly ash and a range of heavy metals. Neutralization/absorption of acidic pollutants, namely the NOx and SOx gases, prior to the fly ash filtration and treatment is essential to avoid damage to the filter media and excess of emissions. This operation is realized by the DeNOx (NOx reduction) and the FGD (SOx reduction) systems and is carried out by several techniques, including injecting a quantity of lime, limestone slurry, activated carbon or sodium bicarbonate, proportional to the pollutant concentrations.

In FGD applications, to calculate and precisely adjust this pollutant reduction, on-line monitoring of SO₂ (precursor of SO₃ and sulfuric acid derivates) must be set on the process upstream of the abatement plant.  The advantage of flue gas Process monitoring with ENVEA’s MIR 9000ASD  analyzer ensures that the pollutant abatement function is optimized, whilst reducing the overuse of valuable materials in the abatement process, in turn providing cost savings to the plant operator and minimizing pollutant releases. Measuring additionally the water content would additionally allow the detection of a possible leak in the boiler.
