Phosphonates are used due to their cost-versus-performance ratio and are easily formulated by neutralizing to reduce their corrosivity and are easily made into combination (multiuse) products. Oil field scales may also be the complex salts of iron such as sulfides, hydrous oxides, and carbonates. Polyacrylates are very effective where NORM (Naturally Occurring Radioactive Material) exist and have a high temperature tolerance. A triphosphonic acid based on adenosine monophosphoric (AMP), PayZone SI 139 scale inhibitor inhibits calcium carbonate, calcium sulfate, and barium scales in light-density completion, treatment, and injection fluids, including seawater. The as-prepared CCQDs have excellent scale inhibition performance for CaSO 4 and BaSO 4. For cold water applications we suggest you consider the "cold water" scale inhibitor as it contains quite a bit more food grade phosphate crystals. These can include products that can be squeezed, batched and continuously injected. The hot water heater scale inhibitor is designed to work with most hot water systems including boilers and tankless or tank-type (gas or electric) water heaters. Phosphate esters, in some lower temperature applications, show better performance than phosphonates. This chemical inhibitor solution is injected continuously into the matrix of the fluid by precipitation and adsorption squeeze treatments. These precipitates are alkaline earth metal scales. Most of the scale inhibitors and dispersants currently in use are high molecular polymers. Brine overflush pushes the main treatment to the desired depth in the formation away from the wellbore. Scale inhibitors are a type of chemical whose main applications is the treatment of fluids, as it helps in avoiding any accumulation of formation of undesirable materials in the fluids they are used in. Scale inhibitors are coarsely classified as organic and inorganic (Viloria et al., 2010). Among the various types of oilfield scale inhibitors, the carboxylate/acrylate type segment accounted for the largest share in 2014.

Protect your heating system against scale and corrosion extending the life of your central heating system. Phosphonates are used due to their cost-versus-performance ratio and are easily formulated by neutralizing to reduce their corrosivity and are easily made into combination (multiuse) products. 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. Oil field scales may form in one of following two ways: 1. The scale inhibitor components mainly include some natural dispersants, phosphonic acids, phosphonic acids, and phosphonic sulfonic acids, and high molecular polymers. The detailed factors in the selection of scale inhibitor candidates for consideration in the performance tests include: Type of scale: Best scale-inhibitor chemistry based on the scale composition should be selected. 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. The content of impurities will also increase. 2. Solenis offers a complete portfolio of scale inhibitors and antiscalants for controlling the formation of virtually any type of scale, including common calcium scales and less common barium, magnesium, manganese, silicate and sulfate scales. Angiotensin-converting enzyme inhibitors (ACE inhibitors) are a group of medicines that are mainly used to treat certain heart and kidney conditions; however, they may be used in the management of other conditions such as migraine and scleroderma.. Polymeric dispersants or sludge conditioners are added with the p… For example, when the concentrations of calcium ion and carbonate ion exceed the solubility of the calcium carbonate reaction product, a solid phase of calcium carbonate scale will form as a precipitate. They block the production of angiotensin II, a substance that narrows blood vessels and releases hormones such as aldosterone … Contact us for a meeting. Inhibit the potential of minerals to form scale. 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. Available in hundreds of stores nationwide. Scale can diminish performance & shorten the life of equipment. Can be divided into anode type scale inhibitor, cathode type scale inhibitor or mixed type scale inhibitor. By continuing to use this site, you consent to the use of cookies. In this article, a new kind of green scale inhibitor, carboxyl carbon quantum dots (CCQDs), was synthesized through a simple method of thermal decomposition of citric acid. Preferably, no scale inhibitors are used, and other ways of prevention are required. Given the characteristics of the Miravalles fluids, the best types of inhibitor are polymers with carboxylic functional groups. These compounds form sludge, which, when properly conditioned with polymers, is removed from the boiler via blowdown. Phophonates, phosphate esters and polyacrylates are the three main types of scale inhibitors used in the oil and gas industry. Scale inhibitor compositions, alone or together with polymeric structures, are described and characterized by having, in addition to a phosphonomethylamino group, a sulfonic acid and/or carboxylic acid group. After the injection of the three solutions, the well is shut-in for about 24 to about 48 hours. Phosphate treatment programs precipitate calcium and magnesium hardness from boiler feedwater in the form of hydroxyapatite and serpentine. Oilfield scales are generally inorganic salts such as carbonates and sulfates of the metals calcium, strontium, and barium. Or. Scale inhibitors can be applied down hole in a problem production well or in the surface facilities to delay the onset of these undesirable precipitates. IsoNet® & ScaleX2®- Inhibitor Technologies from OptiPure A Review of Solid-Form Scale and Corrosion Inhibitors 'Share on Twitter' By Michael Hunter, Global Technical Director, APTech Group, Inc. Introduction / History of Solid Water Treatment. 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 chemical dissolution involves the chelation of carbonate and sulfate scales using phosphorous and inorganic compounds. A triphosphonic acid based on adenosine monophosphoric (AMP), PayZone SI 139 scale inhibitor inhibits calcium carbonate, calcium sulfate, and barium scales in light-density completion, treatment, and injection fluids, including seawater. Main scale-inhibitor treatment, which contains the inhibitor chemical, is normally in the concentration range of 2.5 to 20%. Scale inhibitors are typically either phosphorous containing molecules or water-soluble polymers. The scale inhibition mechanism of scale inhibitors includes four kinds of reaction complexation mechanism, lattice distortion mechanism, electrostatic repulsion mechanism, and … In this type of treatment, a high-efficiency scale inhibitor is pumped into the matrix surrounding the fracture face during leakoff .
