Emission and raw gas monitoring

Mercury monitoring

Mercury is a highly toxic heavy metal, for both people and the environment. More and more countries around the world are therefore imposing more stringent requirements with respect to the limitation of industrial mercury emissions. The resulting emission limits are many times lower than for other flue gas components.

Continuous mercury emission monitoring

Our extractive mercury analyzers are certified systems that provide continuous mercury monitoring in the concentration range of a few micrograms per cubic meter. These low-maintenance devices are extremely robust and have proven themselves in a wide range of applications.

Mercury measurement and analysis with experience

Mercury analyzers from DURAG GROUP can be used not only for continuous emission monitoring. Depending on their design, these analyzers can also be used to measure significantly higher concentrations in raw gas or to determine different mercury species. This enables the evaluation and optimization of mercury reduction measures in flue gas treatment, which can prevent emissions. DURAG GROUP today has more than 25 years of experience in continuous mercury monitoring.

How mercury analysis works

A continuous mercury monitoring system consists of an mercury analyzer and a sampling system. The sampling system in turn consists of a sampling tube and probe that extracts the sample from the duct. A heated sample gas line transports the sample gas from the probe to the continuous mercury analyzer. The sample is processed in the analyzer. Finally, mercury detection is carried out by means of atomic absorption spectroscopy. 

Importance of mercury monitoring

Continuous mercury monitoring is crucial for plant operators to comply with the individual requirements for their operation permit and to take the measures necessary to reduce their environmental impact. Local authorities, government agencies, and other stakeholders can track compliance and policies related to mercury emissions and reduction.
