Abstract Information :
The paper will cover the Sample Gas Handling and Conditioning part of Continuous Emission Monitoring Systems. Continuous monitoring of gaseous pollutants with a CEMS is the commonly used way to not only know the amount of emitted concentrations before any control system (input into i.e. DeSOx or DeNOx Scrubbers, filters, etc.), but also the actually emitted concentrations (= efficiency control of the control systems).
The typical extractive CEMS consist of basically three components:
Sampling System / Analyzer System / Data Acquisition System
The Sampling System for gas analysers includes the following sub-components:
- Gas Sampling Probes
- Heated Sample Gas Lines
- Sample Gas Filters
- Sample Gas Treatment (i.e. NO2 to NO converters for NOx analysers)
- Sample Gas Coolers
- Condensate Treatment
The design and the quality of the sample handling system widely influences the accuracy of the analysers used to monitor the pollutants.
The design of an innovative and reliable Sampling System has to take into account the type of pollutants to be measured, as well as the stack gas condition. The different possible solutions will be presented and discussed, as well as the special requirements when continuously monitoring the emission of Nitrogen Oxides Total Hydrocarbons, and Total Mercury.
