Improved method for vapor phase mercury capture for Dry Scrubber AQCS
US EPA regulations regarding mercury capture in electric utility and industrial coal fired boilers, cement kilns and waste incinerators have resulted in numerous mercury mitigation strategies. Often these mitigation strategies include activated carbons and halogen additives applied to fuels or co-mixed with the activated carbons. These methods are effective, but can create secondary concerns regarding system corrosion and halogen levels in ash disposal. While PAC continues to be the leading sorbent utilized, atlaSORB™ meets the needs of customers seeking net zero carbon product. AtlaSORB™ fills the need for a more effective mercury capture reagent having no corrosion potential and an opportunity to lower overall cost of mercury compliance when used alone or in combination with conventional sorbents and methods. This is because in recirculating dry scrubbers nearly 100% of the reagent is utilized. AtlaSORB™ reagent produces a stable solid mineralized mercury compound also found in nature that is truly sequestered in dry scrubber residuals landfills. AtlaSORB™ has been well received by dry scrubber users because it is a non-carbon, halogen-free sorbent with a high effectiveness per pound of product.
