Coal Fired Power Plants Remove Mercury Without Corrosion Concerns

Over the years, we've seen coal fired power plants using powdered activated carbon (PAC) to help them meet mercury emissions compliance. The majority of the PACs on the market are brominated/halogenated products that pack an oxidizing punch to help remove mercury from flue gas. Unfortunately, some studies indicate that there may be a correlation between bromine and corrosion in plant equipment, which can lead to costly repairs or even system replacement over time.

Carbonxt, offers a non-halogenated oxidizing PAC that has been proven to effectively remove mercury without the corrosion concerns some have come to associate with bromine (halogen)-based PACs.

Coal Fired Power Plants Remove Mercury Without Corrosion Concerns

The unique pore structure of Carbonxt PACs permits the rapid adsorption and removal of mercury from combustion gases at a wide range of temperatures. These distinctive physical features combined with enhanced activity result in a high capacity sorbent for mercury capture.

Carbonxt has many benefits for coal fired power plants:

  • Designed for in-flight gas-phase removal of mercury
  • No corrosion to pipes or equipment saves plants a significant amount of money over the long term
  • Injection rates can be tailored to meet plant needs - from trim up to the most challenging plant applications
  • Equivalent or better than the latest generation of brominated carbons in electrostatic precipitators (ESP), fabric filter, and Compact Hybrid Particulate Collector (COHPAC) configurations
  • Lower injection rates due to high capacity mercury capture results in cost savings
  • Rapid adsorption and removal of mercury from combustion gases at a wide range of temperatures
  • Minimal impact on fly ash
  • Can be applied upstream or downstream of the air heater
