Tri-Mer Corporation, a specialist in air pollution control, has announced its latest development in the control of NOx emissions at temperatures as low as 350°F.

UltraCat Catalyst Filters can provide up to 95% NOx removal at the operating temperatures of most industrial boilers. Dioxins can also be destroyed at 97-99% efficiency.

In addition to NOx and dioxin removal, UltraCat filters are designed to capture particulate to low levels. Typical outlet levels are less than 0.001 grains/dscf (2.0mg/Nm3). For the control of SO2, HCl and other acid gases, the system incorporates dry sorbent injection using sodium bicarbonate or lime. The result is 90-98% removal of these contaminants, according to Tri-Mer Corporation.

The Tri-Mer system is modelled on a robust baghouse configuration and uses a reverse pulse-jet cleaning action. It is designed for simplicity of operation and maintenance, as well as low operating costs.
