Agentes de control de incrustaciones de sulfato en sistemas acuosos de ph bajo; proceso para inhibir o prevenir la formacion de incrustaciones de sulfato .

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.
