Abstract: A process for in situ immobilization of metals in waste stack affected zones including a waste stack and any adjacent boundary zone. One form of the process includes: (a) forming at least one treatment passageway which extends within the waste stack affected zone; (b) injecting a treatment liquid into the treatment passageway; said treatment liquid including at least one microbe nutrient which is capable of sustaining activity of the at least one microbe; (c) providing at least one microbe in sufficient proximity to the treatment passageway to receive treatment liquid therefrom; said at least one microbe being capable of growing in the presence of said treatment liquid; said at least one microbe also being capable of producing microbial sulfides which are sulfide by-products of microbial activity in the waste stack affected zone; (d) reacting the microbial sulfides in situ with metal ions or metal-containing compounds contained in said waste stack affected zone to form metal sulfides; (e) reducing solubility of the metal ions or metal-containing compounds contained in the waste stack affected zone as a result of forming the metal sulfides; and (f) inhibiting the migration rate of metal ions or metal-containing compounds within or from the waste stack affected zone.

Abstract: The invention encompasses methods of preventing corrosion of vessel sidewalls. In one aspect, the invention includes an anti-corrosion treatment method of reducing internal corrosion of an ammonium phosphate holding vessel comprising providing at least one quaternary-amine-comprising compound within the vessel. In another aspect, the invention includes a treatment method of reducing corrosion of a vessel sidewall surface comprising utilization of a quaternary amine to form a protective layer on the vessel sidewall surface. In another aspect, the invention includes an anti-corrosion treatment method of reducing corrosion of a vessel comprising: a) flowing a liquid into the vessel; b) adding at least one compound to the liquid, the compound being added to a concentration which exceeds the solubility of the compound in the liquid; and c) coating the compound onto an internal surface of the vessel to form a protective layer over the internal surface. In yet another aspect, the invention includes an anti-corrosion mixture, comprising: a) an ammonium polyphosphate solution; and b) a quaternary-amine-comprising compound within the ammonium polyphosphate solution.
