Catalyst Filters Capture Particulate At Low Levels

Tri-Mer Corp. has announced an advancement in the control of NOx at temperatures as low as 350 degrees Fahrenheit.  UltraCat catalyst filters provide up to 95% NOx removal at the operating temperatures of most industrial boilers. Dioxins are also destroyed by the catalyst at 97% to 99% efficiency.

For carbon monoxide, a strategy for meeting the Boiler MACT is to tune boiler combustion to lower the CO output. While this can increase NOx production, the additional NOx is removed by the UltraCat filters. Often NOx requirements are already in place due to other federal and state air regulations.

Along with high NOx and dioxin removal, UltraCat filters capture particulate to low levels. Typical outlet levels are less than 0.001 grains/dscf  (2.0 mg/Nm3).  For boiler MACT compliance, a level of 0.002 lbs/MMBtu is typical, and less than 0.004lb/MMBtu is guaranteed. 

The UltraCat system incorporates dry sorbent injection using sodium bicarbonate or lime. The result is 90% to 98% removal of these contaminants.  With very few exceptions, these efficiencies will meet regulatory limits. Mercury removal options are also available.
