摘要： This invention relates to an improved method of inhibiting corrosion and calcium sulfate and calcium carbonate scaling in thermal and membrane desalination processes. The method includes adding a composition having an acrylic acid 2-acrylamido-2-methylpropyl sulfonic acid copolymer, combined with a synergistically effective amount of oligomeric phosphinosuccinic acid to seawater or recirculation brine in a desalting process to produce water for drinking and industrial applications. The method also includes adding a composition including mono, bis, and oligomeric phosphinosuccinic acid adducts to the desalting process.

摘要： On-Line and Off-Line methods of simultaneously cleaning and disinfecting an industrial water system are described and claimed. The methods involve the addition to the water of the industrial water system of a Compound selected from the group consisting of the alkali salts of chlorite and chlorate and mixtures thereof; and an acid, followed by allowing the water in the industrial water system to circulate for several hours. The reaction of the alkali salts of chlorite and chlorate and acid produces chlorine dioxide in-situ in the water of the industrial water system. The chlorine dioxide kills microorganisms and the acid acts to remove deposits upon the water-contact surfaces of the equipment. An alternative method involves the use of a chelating agent and a biocide. Other possible cleaning and disinfection reagents may be added as needed including corrosion inhibitors, chelating agents, biocides, surfactants and reducing agents. These cleaning and disinfecting methods work in a variety of industrial water systems including cooling water and boiler water systems.

摘要： Polyether polyamino methylene phosphonates, when added to various industrial water systems in concentrations between 0.1 mg/L and 50 mg/L, control silica/silicate deposition. In particular, this stabilization can be achieved under severe conditions which include elevated pH, high dissolved solids content, and high saturation levels of calcium carbonate.

摘要： The current invention relates to the inhibition of scale deposits in a slurry or solution under acidic conditions. The current invention uses an aqueous synthetic mixture comprising a phosphate, phosphonate, anionic polymer, or combinations thereof in the slurry and/or solution to inhibit scale deposition from acidic process streams. The control of scale under acidic conditions is difficult because the acidic environment renders most known inhibitors ineffective. The claimed invention causes a significant decrease in the scale generated allowing for reduced down time of systems for de-scaling procedures and thus increasing production.
