Mercury Removal
Amended Silicates is injected into coal combustion gases upstream of the TOXECON baghouse. Amended Silicates interacts with the mercury, chemically modifying it into an inert and insoluble state. Because Amended Silicates is non-flammable, high concentrations of Amended Silicates do not pose any combustion hazard to the baghouse or ash silos. In addition, Amended Silicates does not produce any noxious or corrosive off-gases
Balance of Plant Impacts
As a non-carbon, silicate based reagent, Amended Silicates has similar physical and chemical properties to fly ash itself. There is no evidence of buildup, erosion or any other potential impacts when using Amended Silicates.
Baghouse
Novinda has researched the impact of Amended Silicates on various bag types. As a non-carbon, silicate based sorbent, Amended Silicates has similar physical and chemical properties to fly ash itself. To date, no evidence of blinding, buildup or any other adverse potential impacts have been observed.
Preserves Fly Ash Value
Amended Silicates is
100% compatible with concrete, making it an environmentally and fiscally responsible choice for mercury control. Even at the high concentrations expected within a TOXECON baghouse, fly ash containing Amended Silicates can be blended with ESP fly ash for sale as a portland cement replacement. This eliminates the need to landfill any fly ash material from a TOXECON configuration.
Superior Handling Characteristics
As a non-carbon based product, Amended Silicates is non-flammable – an important consideration when choosing a mercury emission control technology. Additionally, Amended Silicates has similar physical and chemical properties to fly ash and has not been observed to produce any noxious or corrosive off-gases. These attributes make Amended Silicates easy to store and handle.
Leachability
Tests have shown that mercury removed by Amended Silicates and contained within the Amended Silicates-fly ash mixture is extremely stable and able to pass stringent
EPA leachability standards.
