Air pollution control vendors have reported booking new contracts for equipment for more than a dozen power plants, with engineering companies reporting new contracts on several facilities to develop design specifications for procurement of mercury control technology. The contracts for commercial systems are attributed to federal and state regulations, including new source permit requirements and consent decrees, which specify very high levels of mercury capture.
A number of different technology approaches have been developed and tested for full scale applications including controls that specifically target mercury as well as those that enhance the removal of mercury from currently installed controls (FGD, SCR, etc). Some of the categories of mercury controls that have been developed include sorbent injection, catalytic oxidation, and multi-pollutant controls.
