Mercury and Associated Trace Metal Chemistry Studies within NOx Control Systems: Applications which fit the following description should be submitted under this funding opportunity title of Mercury and Associated Trace Metal Chemistry Studies within NOx Control Systems (DE-PS26-04NT41898-12). By the year 2010, it is estimated that over 50% of coal-fired utilities will install either selective catalytic reduction or selective non-catalytic reduction units to meet NOx emission limits. Understanding mercury chemistry and process-related speciation mechanisms and transformations related to NOx control systems would provide necessary information to develop more effective, less costly mercury removal processes for industrial and coal-fired boilers. Past research has shown a probable relationship between degree of mercury oxidation and age of NOx catalyst, coal rank, size (or residence time) of NOx control vessel, degree of NOx conversion, amount of SO2 converted to SO3, and ammonia slip. Grant applications are sought to further understand partitioning and chemistry of mercury and other trace metal and organic substances in coal-fired (bituminous, subbituminous, and lignite) systems utilizing SCR/SNCR or ammonia injection. Specifically, statistical analysis clarifying the importance of each of these identified parameters and/or their interactions on chemical intermediaries and mechanisms is sought.
