Analyzers for use in emission control
Analyzers for use in emission control are of identical design to those used in other
areas of process analysis. They must, however, meet particular requirements
and, in many countries, pass a dedicated suitability test to get the certification for
use in emission monitoring applications.
The high number of components which may be present in the exhaust gases requires
selective analyzers whose cross sensitivity is either very low or well known
and thus can be taken into account by calculations. Furthermore, the analyzers
must be easy to calibrate and deliver correct and reproducible results. High availability
and low maintenance requirements are also part of the certification conditions.
Emission monitoring measurements require also well designed sample gas extracting
and conditioning systems because of the high temperatures as well as
dust and water content of the flue gases. Gas sampling must deliver a representative
proportion of the flue gas stream which sometimes requires more than one
sampling point.
