摘要： In systems and methods for treatment of underground contamination, ferrous sulfide is provided as a substantially insoluble material in an underground formation. The ferrous sulfide accordingly may remain substantially in place, even over long periods of time, regardless of underground water movement or diffusion. As a result, the ferrous sulfide may act continuously to chemically reduce and remove contamination. When used for treatment of chromium ore processing residue contamination, the ferrous sulfide may remain in the pores of the soil or residue. As hexavalent chromium diffuses from the soil or residue, it is reduced by the ferrous sulfide. The ferrous sulfide may be injected as a liquid into the underground formation, and then change to a more solid form. Chlorinated solvent contamination, dissolved chromium from other than COPR contamination, and other dissolved metals may also be treated.

摘要： A method for treating flue gas may include adding iron to a slurry in a ratio between approximately 20-to-1 and 5000-to-1 by weight of iron to a weight of mercury, selenium or other heavy metal to be removed from the flue gas, and contacting the slurry with the flue gas in a flue gas desulfurization system. A system for treating flue gas may include a scrubber, a slurry tank, and a water source. Water and limestone may be combined in the slurry tank to form a limestone slurry. At least a portion of the limestone slurry may be used to treat flue gas in the scrubber. Iron may be added to at least a portion of the limestone slurry used to treat flue gas in the scrubber. The iron used in either the method or system may be a ferrous or ferric salt, or elemental iron.
摘要翻译：用于处理烟道气的方法可以包括将浆料中的铁以约20-1比5000重量％的比例添加到汞，硒或其它重金属从烟道中除去的重量气体，并在烟道气脱硫系统中将浆料与烟道气接触。用于处理烟道气的系统可以包括洗涤器，浆料罐和水源。水和石灰石可以在浆料罐中组合以形成石灰石浆料。石灰石浆料的至少一部分可用于处理洗涤器中的烟道气。铁可以添加到至少一部分用于处理洗涤器中的烟道气的石灰石浆料中。在该方法或系统中使用的铁可以是亚铁或铁盐或元素铁。
