Abstract Information :
Following the international consensus to strengthen environmental control and reduce the use of Hg in human activity, through the Minamata Convention, a growing number of countries have begun to implement continuous monitoring of emissions of this pollutant from activities likely to emit it, such as waste-to-energy, non-ferrous processes or coal-fired power plants. Although it may seem at first sight to be just another gaseous parameter to be added to those already measured, such as SO2 or NOx, monitoring Hg in stack emissions raises unique challenges, due to its specific chemical properties, which require a dedicated monitoring system, with very specific features. All CEMS dedicated to emissions monitoring must therefore meet such unique challenges, be they the highly reactive properties of ionic mercury, interference with other gases, or complex calibration solutions. In this presentation, we will demonstrate that an Hg CEMS solution can be operated with minimal operating and maintenance effort, while ensuring accuracy can be maintained over time by the plant operator.
