Mercury Control Technologies

This brochure gives an overview of Nalco mercury control technologies, including:

MerControl 7895 – Mercury Oxidant Catalyst

technology augments oxidation of mercury released during the combustion of coal and can remove over 90% of mercury when used in conjunction with a w-FGD or SDA/FF. When applied with activated carbon injection, the addition of MerControl 7895 technology significantly reduces total mercury control costs while maintaining fly ash resale value.

MerControl 8034 – WFGD Mercury Re-emission Control

While w-FGDs will capture the oxidized form of mercury, some w-FGDs convert oxidized mercury back to its elemental form (known as Mercury Re-emission) resulting in reduced capture efficiency and increased stack emissions. technology can reduce up to 100% of mercury re-emissions in w-FGD scrubbers while preserving gypsum quality and decreasing emission rates.
