Mercury Emission Control

Mercury (Hg) is a naturally occurring element that humans can neither create nor destroy. Because of its inherent presence in the earth’s crust, mercury can be found in varying amounts and in a number of forms or compounds within coal deposits. When coal is burned, various forms of mercury can be emitted as gases, along with other compounds and elements.

The most effective method for removing mercury from coal combustion gases is the introduction of a fine powder material into the gas stream. This material interacts with gaseous mercury, removing it from coal combustion gases. Particles containing the mercury are then captured in the power plant’s particulate capture systems.

Amended Silicates® is a patented mercury removal reagent that effectively removes mercury from coal-fired power plants. Amended Silicates is the first commercially available non-carbon reagent that is 100% compatible with fly ash use in concrete. Amended Silicates offers economic and environmental advantages not available with other mercury removal products.
