COMPOSITION FOR TREATMENT OF COOLING WATER Russian patent published in 2005 - IPC

FIELD: special compositions.

SUBSTANCE: invention relates to compositions used for treatment of cooling water with aim for prevention formation of saline deposits with the corrosion effect on equipment contacting with water. The composition comprises the following components, wt.-%: oxyethylidene diphosphonic acid, 1-57%; nitrilotrimethyl phosphonic acid, 1-57%; dialkyldimethyl ammonium chloride, 1-2%; propylene glycol, 1-30%, and water, the balance. Invention provides the development of polyfunctional homogenous, nontoxic and stable in storage composition. The development of highly concentrated composition suitable for transporting is possible. Invention can be used for treatment of cooling water in water supply systems of industrial plants. The composition can be used for prevention of formation of carbonate, sulfate and iron oxide deposits and for destruction of carbonate salt deposits on heat-transferring surfaces that allows its using for cooling water in return cycles of water supply and to enhance effectiveness of heat exchange in simultaneous inhibition of corrosion.

EFFECT: enhanced effectiveness and valuable properties of composition.
