Ammonia Sorbent Traps
Ammonia (NH3) sorbent traps are used to measure ammonia levels at SCRs/SNCRs in order to monitor catalyst health and optimize ammonia injection rates.
The analysis is done using ion chromatography.
Measuring ammonia slip through the SCR/SNCR
Measuring ammonia between layers of the SCR to monitor catalyst layer performance.
Tying ammonia slip to catalyst health - particularly as it applies to mercury oxidation efficiency in the last layer of the SCR
