Mercury Emission Control

Effective removal with Powdered Activated Carbon (PAC)

 

To date, coal-fired power plants have become the leading contributor to widespread, global mercury pollution.

As a result, federal emission standards are in place to regulate the volume of pollution a plant is able to emit. Tri-Mer’s UltraCat system is compatible with standard mercury emission control techniques.

Control of mercury is notoriously difficult: each instance is analyzed individually, and customized solutions are engineered. A few general observations can be offered, however.

Mercury Conrol Dioxin Removal

We sell industrial mercury removal equipment for NOx and dioxins control. Tri-Mer Ceramic Catalyst Filter System

Installations that generate both NOx and dioxins are ideal applications for Ceramic Catalyst Filter Systems technology.

  • The catalytic filters can handle very high particulate loads while maintaining exceptionally low outlet levels.
  • Just as the addition of dry sorbents for the removal of acid gases is effective, so is the addition of powdered activated carbon (PAC) for mercury.
  • In general, regular PAC becomes less effective with temperature, topping out around 400°F. The chemical composition of the pollutant gas plays a major role; hence, the difficulty of blanket statements.
  • At higher temperatures, brominated PAC is required. According to the manufacturers of brominated products, temperatures of 500°F to 800°F are acceptable.
  • Significant levels of mercury removal have also been achieved with injected powdered trona.
  • Many new sorbents for mercury removal have been introduced in recent years; some of these appear very promising.
