Mercury monitor tests pollution control technology

Cemtrex continuously monitored total mercury using its SM-4 and the Shaw Group verified the SM-4 data accuracy by pulling weekly sorbent trap samples.

Cemtrex has successfully completed a test program under its contract with the Electric Power Research Institute.

The company measured total mercury in stack gas emissions from EPRI's ReACT program, a multipollutant removal technology for flue gas emissions at Sierra Pacific's North Valmy coal-fired power station in Valmy, Nevada.

The Cemtrex SM-4 mercury monitor was in operation for several months and had over 95% data availability.

While in operation the SM4 passed all elemental daily calibration checks and passed every ionic system integrity test.

The thermo catalytic convertor proved 100% efficient and never had to be replaced.

The SM-4 performed never required any maintenance or repair.

Cemtrex was hired by EPRI to accurately monitor and report ReACT system efficiency.

Both Cemtrex and Shaw Group monitored total Hg concentrations using different methods.

Cemtrex continuously monitored total mercury using its SM-4 and the Shaw Group verified the SM-4 data accuracy by pulling weekly sorbent trap samples.

The SM4 monitor was used by EPRI in measuring extremely low level mercury concentrations, ranging from 0 to 100ng/m3 of gas in its test process stream at both inlet and outlet locations.

Because of high- efficiency ReACT systems the mercury concentrations extracted from the process on the outlet side were averaging 0.015 ug/m3.
