With solutions like Gravex® mixed beds, Graver supports utilities in extending the life of steam generators, optimizing efficiency, and maintaining high-quality water throughout the cycle.
Our Filtration Solutions for Steam Generation
Our collection features the following types of steam generation ion exchange resins:
1. GR-2-0 NG (H): It is a high-performance mixed bed ion exchange resin specifically engineered for nuclear steam generators. It ensures ultra-pure condensate, helping maintain the highest water quality throughout the steam cycle. This resin effectively controls sodium and chloride levels, preventing corrosion and deposit formation in boilers and turbines. Its special macroporous cation in the amine form is highly selective for sodium, while the anion component keeps chloride at extremely low levels. Designed for long service life, Gravex® GR-2-0 NG (H) helps utilities maximize efficiency, maintain equipment integrity, and extend the operational life of steam generators.
2. Gravex® GR-3-16 US NG (H/OH): It is a high-performance mixed bed ion exchange resin engineered for use in steam generator condensate polishing and demineralization systems. It combines strong cation and anion resins to remove dissolved impurities, including sodium and chloride, ensuring ultra-pure water for high-efficiency steam production. Gravex® GR-3-16 US NG (H/OH) is ideal for utilities and industrial plants seeking reliable steam generation with ion exchange resins that enhance operational efficiency and longevity.
Key Features of Our Filtration Solutions for Steam Generation
The following features of our filtration solutions for steam generation equipment have contributed to their popularity.
• Optimized mixed bed ratios: Specialty mixed bed formulations provide the highest cation capacity, ensuring efficient removal of impurities. These boiler feedwater ion exchange resins help maintain peak performance in steam generators.
• Morpholinium form cation: Available as an individual bed or mixed bed component, this cation maintains cycle pH and reduces the need for additional amine treatment, simplifying operation and lowering costs.
• Ultra-low chloride anion: Delivers minimal chloride leachable, offering the ultimate protection for steam generators. This feature enhances the steam generator water treatment resins' performance and reliability.
• Nuclear-grade options: Graver offers high-purity ion-exchange media for demineralizing steam generator water, including both cation and anion Gravex products, designed for demanding nuclear and industrial applications.
• Comprehensive resin solutions: From steam generator demineralizer resin solutions to full mixed bed systems, Graver Technologies provides reliable products that ensure ultra-pure water, protect equipment, and maximize operational efficiency.
Applications of Steam Generation Ion Exchange Resins
Graver Technologies’ steam generator water treatment resins are used across a wide range of industrial and power generation settings to ensure high-purity water, protect equipment, and optimize performance. Key applications include:
• Nuclear Power Plants: High-purity ion-exchange media for demineralizing steam generator water helps maintain cycle pH, prevent corrosion, and extend the life of critical components.
• Thermal and Fossil Fuel Power Plants: Boiler feedwater ion exchange resins remove dissolved minerals and impurities, safeguarding turbines and heat exchangers.
• Industrial Steam Systems: Reliable steam generator demineralizer resin solutions provide consistent high-purity water for manufacturing, chemical processing, and large-scale heating applications.
• Condensate Polishing Units: Mixed-bed steam generator water treatment resins maintain ultra-low chloride levels, supporting operational efficiency and reducing maintenance needs.
Critical Ion Exchange Technology for Steam Generation
Steam generators in Nuclear Pressurized Water Reactors (PWR) electric generating stations are vital components in the power generation cycle. In addition to high-purity condensate, many steam generators are used to blow down demineralizers to help maintain quality for efficient operation and extended steam generator life. Graver Technologies has worked with several utilities to evaluate and develop specialty products to maintain an optimum generator and cycle performance. Several special cation-to-anion ratio mixed beds are quite useful, providing additional cation capacity to extend run length. One Gravex® mixed bed is made with a macroporous cation in the amine form. This particular morpholinium form cation resin is selective for sodium, thus maintaining high purity levels. Our Ultra-Low-Chloride anion can be utilized to help keep chloride at the lowest level possible in a high pH environment. Although developed for condensate, the low ppt chloride Gravex is beneficial for steam generator performance. Graver Technologies has the right product for your steam generator blow-down demineralizers.
