Scale Inhibitor 4300 High Polymer
Scale Inhibitor 4300 Rx is a high performance polymer based scale inhibitor.
Scale Inhibitor 4300 RXSOL is a high performance polymer based scale inhibitor, specifically developed to prevent both calcium carbonate and calcium sulfate salt deposits in water systems. The unique feature of Scale Inhibitor 4300 RX is the improved overall performance for inhibiting these calcium scales over conventional polymaleic acids, acrylate polymers and phosphonates. This product, a maleic multipolymer, will also prevent the formation of other scales such as calcium oxalate. Scale Inhibitor 4300 RXSOL will also disperse colloids and fine particles such as clay.
Scale Inhibitor 4300 RXSOL is a specially formulated blended polymer-based scale inhibitor, developed to provide superior control of inorganic scale deposition in offshore and onshore oilfield production systems.
The product is highly effective against mixed sulphate and carbonate scales, particularly barium sulphate, strontium sulphate, calcium sulphate, and calcium carbonate, which are commonly encountered in high-salinity formation waters and seawater injection systems.
Scale Inhibitor 4300 is specifically designed for scale squeeze applications, offering excellent adsorption onto reservoir rock surfaces and controlled, long-term inhibitor release, thereby extending squeeze life and reducing intervention frequency.
Mechanism of Action
Maleic polymers are known to be excellent calcium carbonate inhibitors and crystal modifiers but many exhibit only fair calcium sulfate deposit control. A new polymer, Scale Inhibitor 4300 Rx, has been developed to overcome this problem. Scale Inhibitor 4300 Rx contains maleic polymer and a unique combination of other functionalities to provide both superior calcium carbonate and calcium sulfate inhibition, also outperforming HEDP. Preventing calcium sulfate scale is important in water systems treated with sulfuric acid for pH control or if using seawater or briny waters. Also removing sulfur oxide gases in scrubbing systems can result in sulfur containing calcium deposits.
Scale Inhibitor 4300 Rx polymer inhibits scale buildup on surfaces through at least three mechanisms:
- Solubility enhancement or threshold effect, which reduces precipitation of low solubility inorganic salts.
- Crystal modification, which deforms the growing inorganic salt crystals to give small, irregular, readily fractured crystal that do not adhere well to surfaces.
- Dispersing activity, which prevents precipitated crystals or other inorganic particles from agglomerating and depositing on surfaces.
