Description:
The Phase I objective is to develop a sampling system that differentiates the elemental and oxidized forms of mercury for reliable sample transport to any of several existing real-time analyzers. Mercury emission from combustion sources is recognized as a major concern to the Nation's air quality. However, mercury emissions measurements from coal-fired utility boilers are difficult to make due to low mercury concentrations and interfering gas species. A sample conditioning system that removes interfering species and stabilizes the mercury for measurements would allow real-time, continuous measurements.Control of mercury emissions from coal-fired utility boilers currently is being considered, and if implemented, will likely cost billions of dollars each year. Apogee Scientific, Inc.'s proposed sampling system could assure compliance with regulations and lower costs through more appropriate technology implementation and advanced process control. Furthermore, the health effects of mercury emissions from coal-fired combustion sources cannot be fully evaluated nor can controls be cost-effectively implemented unless the emissions can be accurately measured. The proposed system will enable accurate mercury measurements.
