What are EES Amended Silicates™?

In general, Amended Silicates are Advanced Chemical Products that utilize a combination of an internal non-carbon substrate and a small coating of active chemicals to perform a needed chemical or physical function.

By separating the properties of the majority of the mass of the product (which is the mass included in the internal substrate) from the external chemical coating, Amended Silicates can be created that selectively and independently address all the desired benefits, without any of the major concerns.

Amended Silicate powders for mercury control for example, utilize an internal substrate composed of aluminosilicates selected to make the product compatible in the fly ash with use in concrete, fly ash stability, and lower cost of the product.

The chemical components on the external surface of the particle substrate are chosen and manipulated to be particularly effective at capturing mercury in the most stable form possible, and doing other good things for the balance of plant, such as reducing the fly ash resistivity (which increases ESP performance), reducing overall leaching of metals from the fly ash, and eliminating the need for corrosive halides.

Using this basic Amended Silicate platform, Products have been created for many different applications, including:

  • AS-DryScrub – a product that is particularly effective at capturing mercury from dry scrubbers and circulating dry scrubbers.
  • AS-HgOX – a product designed to catalytically oxidize mercury in the flue gas.
  • AS-ULTRA – a product developed with an extremely high mercury capture rate, for plants without scrubbers or those that desire to capture all of the mercury before their wet scrubber.
  • AS-DIOX – a product developed to catalytically destroy dioxins, furans, and other toxic organics from waste incinerators and other industrial processes.

Each one of these products have been designed, taking advantage of the unique Amended Silicate platform, to provide additional associated benefits and reverse any potential negative balance-of-plant challenges associated with their use.
