types of scale inhibitors

These precipitates are alkaline earth metal scales. By continuing to use this site, you consent to the use of cookies. The as-prepared CCQDs have excellent scale inhibition performance for CaSO 4 and BaSO 4. Or. The content of impurities will also increase. The “scale squeeze” is an operation where long-term protection against mineral scale precipitation from the perforations is provided through the topside process. Scale Inhibitors Normally, two types of scale-inhibitor chemistry are used: phosphonates and/or polymers. ; The severity of scaling: Fewer products are effective at high scaling rates. Phosphate treatment programs precipitate calcium and magnesium hardness from boiler feedwater in the form of hydroxyapatite and serpentine. Can be divided into anode type scale inhibitor, cathode type scale inhibitor or mixed type scale inhibitor. Scale inhibitors are typically either phosphorous containing molecules or water-soluble polymers. IsoNet® & ScaleX2®- Inhibitor Technologies from OptiPure [170 Pages] Antiscalants/Scale Inhibitors Market research report categorizes the global market by Application (Food & Beverages, Mining, Oil & Gas, Water & Wastewater Treatment, Power & Construction, and Others), Type (Sulfonates, Carboxylates/Acrylic, Phosphonates, and Others), and by … Contact us for a meeting. An electrolytic scale inhibitor has two metals inside it, usually copper and zinc. The squeeze comprises injecting three solutions into the oil or gas well: (1) the preflush solution, (2) the pill solution, and (3) the overflush solution. The scale inhibition mechanism of scale inhibitors includes four kinds of reaction complexation mechanism, lattice distortion mechanism, electrostatic repulsion mechanism, and … When combinations of these anions and cations are present in concentrations which exceed the solubility of their reaction products, precipitates form until their product solubility concentrations are no longer exceeded. Whether your problem is in the formation, downhole, emulsion lines or surface injection equipment, we can recommend the right product for your treatment. Specifically, the method is a novel "squeeze" application. When two incompatible waters (such as formation … The scale inhibitor works on the basis of the degree of scale supersaturation recorded. If properly selected, the scale inhibitor treatment concentrations of only a few ppm into the target stream may be effective to prevent scale problems. Scale Inhibitors Market is Segmented by type such as Phosphonate Scale Inhibitor, Carboxylate/Acrylic Scale Inhibitor, Sulfonate Scale Inhibitor with application such as Power and Construction Industry, Mining Industry, Oil and Gas Industry, Water and Wastewater … There are two fundamental ways to deal with Scale (Hardness): Remove problematic minerals through reverse osmosis to manage TDS, reduce hardness and achieve a favorable mineral balance. TETRA has scale inhibitors which address a broad range of fluid types. It is thought that the phosphorous containing molecules bind to the crystal growth sites preventing further growth, allowing micro fine crystallites to be flushed from the system. In the class of organic scale inhibitors, natural and synthetic polymeric inhibitors are usually used as dispersants in the inhibition process. The difficulty is even greater to increase the concentration of the product. Oilfield scales are generally inorganic salts such as carbonates and sulfates of the metals calcium, strontium, and barium. Scale inhibitors of alkaline earth metal carbonate and sulfates and transition metal sulfide are commonly used in oilfield applications. A method for inhibiting scale formation in an oil or gas well is provided. These products are water soluble, and have a pH in the range of 2 to 7. These are stable at the temperatures encountered in the reservoir, up to 245°C. There are various types of scale inhibitors. Most of the scale inhibitors and dispersants currently in use are high molecular polymers. This chemical inhibitor solution is injected continuously into the matrix of the fluid by precipitation and adsorption squeeze treatments. The method of action of scale inhibitors depends on type. Scale can diminish performance & shorten the life of equipment. For cold water applications we suggest you consider the "cold water" scale inhibitor as it contains quite a bit more food grade phosphate crystals. Protect your heating system against scale and corrosion extending the life of your central heating system. TETRA has scale inhibitors which address a broad range of fluid types. Most industrial and commercial water contains alkaline earth metal cations, such as calcium and magnesium and several anions such as bicarbonate, carbonate, sulfate, oxalate, phosphate, silicate, and fluoride. PayZone ® SI 139 Scale Inhibitor.
