Case Study - Concrete-Friendly Solution to Meeting 90% Mercury Emission Reduction

Given the dynamic condition of mercury legislation, coal-fired utilities are looking for mercury control technologies that can expand to meet not only current but future regulations. Critical in a utility’s decision process is the relationship between regulatory compliance and capital required. Nalco Mobotec’s solutions focus on meeting or exceeding emission requirements while minimizing investment in capital.

MerControl® 7895. MerControl 7895 technology is a stable, water-based solution specifically designed to augment oxidation of mercury released during coal combustion, e.g. bituminous, sub-bituminous, and lignite. MerControl 7895 technology is activated at high temperatures releasing molecular halogen to promote mercury oxidation and alkaline solids to facilitate its capture.

Oxidized mercury is readily captured downstream by wet Flue Gas Desulfurization (FGD) units. When used with activated carbon injection (ACI), the MerControl System commonly requires far less activated carbon than standard halogenated carbon offerings. Lower carbon usage reduces the
load on particulate control devices, decreases concerns with opacity and preserves fly ash quality for concrete use.
