Designed as an instrumental replacement for Ontario Hydro
Method, this is a good tool for testing certification of permanent
CEMM’s, and on-site performance evaluation of Mercury Control
Technologies.
IRM-915 Mercury Stack
Monitor has recently passed RATA (Relative Accuracy Test Audit).
Result are available per request.
Real-Time continuous mercury monitor is based on the analytical
approach of Thermo catalytic conversion and Atomic Absorption
for detection of mercury with Zeeman background correction. This
approach requires no preconcentration on gold eliminating the
associated problems. The use of multipath cell combined with “dry”
converter provides highest sensitivity with no interferences from
the combustion gas matrix. High converter temperature (700°C),
short residence time and up to 1:100 dilution prevents Mercury
atoms from recombining with any “active” species generated
due to high temperature decomposition of flue gas.
Heated Probe and Heated Filter with Dilution/Conversion assembly
are used for “High” or “Low” particulate
loading. Results are reported on “wet” basis as regulation
requires.
Mercury speciation is possible with this system.
