Mercury (symbol Hg) is a naturally occurring chemical element found in varying amounts and as a number of compounds in coal deposits. When coal is burned, various forms of mercury are emitted as gases. Mercury and its compounds are toxic to humans in virtually all states – liquid, gas and solid – and its release is highly regulated by state and federal governments.
The single most effective method for removing mercury from coal combustion gases is to introduce a fine powder material into the flue-gas, which interacts with gaseous mercury and transforms it into an inert and insoluble solid. Particles containing this now-inert mercury are then captured in the power plant’s particulate control systems, effectively removing them from the plant’s coal combustion gases.
Novinda’s Amended Silicates™ patented mercury removal products are reagents that effectively capture 90%+ of vapor phase mercury from the flue gas of coal-fired power plants and industrial boilers. These are the first commercially available non-carbon reagents that are 100% compatible with fly ash resale for use in concrete. Novinda’s Amended Silicates products offer economic and environmental advantages not available with other mercury removal products.
