In-situ capture of Pb, Cd and Hg using Nano-scale sorbents

By June 14 2005, the US EPA is considering implementation of stringent regulations on the emission of toxic metals from Hazardous Waste Combustors. Triton Systems responds to the US Army's need for better sorbents for removal of lead, cadmium and mercuryfrom their demilitarization incinerator plants. Triton's proposed approach is based on in-situ capture of the metal contaminants in the combustor zone of the incinerator using novel nano-scale sorbent particles. In lab scale experiments with simulated fluegases, these nano-scale sorbents have been proven to have very high capacities, greater than 2:1 mass ratios and stability even at temperatures greater than 1400 ¿F. Moreover, capture of metal contaminants takes place through chemical reaction, resultingin a stable non-leachable reaction product that can be safely and easily disposed. The uniqueness of the approach is that the capture of metal contaminants take place in the combustion chamber itself, thereby eliminating the formation of hazardoussub-micron particles. The Phase I Research will focus on the development and optimization of nano-scale sorbents for the removal of toxic heavy metal contaminants. This technology will be used to create new sorbent materials with high removal efficiencyfor effective flue gas clean up. Fabrication of low cost, stable nano-structured sorbents with high capacity would have significant impact on flue gas treatment in coal based power plants, municipal and medical waste incinerators and coal fired boilerutility companies
