Abstract:
A method of recovering mercury and other metal, dioxins, furans and other organic compounds from a gas stream using an adsorption powder, characterized as containing about 40% carbon, about 40% of alkaline material, about 10% cupric chloride impregnated carbon, and about 10% KI3 impregnated carbon, the method comprising the steps of:a) placing a solid phase mercury-containing contaminated soil into a rotary kiln/drum; b) heating said kiln/drum containing said soil to form gaseous and solid components; c) transferring the gaseous component of said soil to an exhaust cleaning unit/afterburner and the solid component of clean soil to a soil cooling unit; d) heating the gaseous component of said contaminated soil in said exhaust cleaning unit/after burner; e) cooling the gaseous component of said contaminated soil; f) adding the adsorption powder to the gasous component; g) transferring the powder-containing gaseous component to a baghouse; and h) releasing the substantially mercury-free gaseous component to the atmosphere.
