    摘要: Scale control agents comprising organic phosphonates, either alone or in mixtures with inorganic phosphonates and also optionally polymers, such as low molecular weight polymeric dispersants. The scale control agents may be applied to inhibit scale formation or deposition in highly acidic aqueous systems by adding these agents to such systems in amounts effective to inhibit metal sulfate scale formation.

    摘要: A method and composition are provided for the operation of an evaporative cooling tower with minimal, or no, blowdown. In some embodiments, the method involves using sodium cation-exchanged softened water as makeup water for the cooling tower, providing a bypass filter for suspended solids removal from the cooling water, treating the cooling water with a composition for control of corrosion and deposition, and using an effective biocide for control of biological growth within the cooling tower system. In some embodiments, a composition is provided that comprises AMPS acrylic terpolymer, sodium silicate, phosphate ions, and polyphosphate ions. When dosed at the recommended levels, the composition controls corrosion of cooling system materials to generally acceptable levels in spite of the extremely corrosive environment resulting from the cycling of sodium cation-exchanged softened water in the cooling tower.

    摘要: A controlled release additive composition for use in aqueous coolant systems is disclosed and comprises a core containing at least one additive component and a polymeric coating including one or more defined polymers substantially surrounding the core. The controlled released additive composition slowly releases the additive component into the aqueous coolant of an open, circulating cooling water system, thereby delivering an effective concentration level of the additive component over an extended period.

    摘要: The present invention relates to a method of treating an aqueous system containing or in contact with metal sulphide scale. The method comprises adding to said system, separately or together, sufficient of a synergistic mixture comprising a THP+ salt, an aqueous solution of a strong acid (and optionally a source of nitrogen) to provide a solution containing from 0.1% to 30% by weight of the THP+ salt at a pH of less than about 1.0. The scale is contacted with said solution, (thereby dissolving at least part of said scale in said solution) and the dissolved scale is withdrawn from the system.
