Task 3.2. Co-Benefits Analysis
The first efforts to improve mercury capture shall be to evaluate potential changes to plant operating practices and additives to increase the effectiveness of the SCR to oxidize mercury and increase overall mercury removal through subsequent capture in the SDA and FF. A short
series of tests will also be conducted to determine the potential of blending Western bituminous coal with PRB coal for enhanced mercury removal across the system. The mercury CEM will be the basis for all co-benefit test results.
