Case Study

In the realm of industrial chemical processes, phenolic compounds are indispensable. They serve as foundational raw materials and intermediates in the production of a myriad of products, from dyes and pesticides to adhesives and photographic developers.

Bipolar membranes represent a leap forward in ion exchange technology. These membranes are engineered by combining anion and cation selective layers with an intermediate interface layer. The unique structure of these membranes allows for the conversion of salts into their respective acids and bases when a reverse voltage is applied across the membrane. This process is facilitated by the migration of charged ions and the dissociation of water molecules at the membrane interface.

At the heart of our NMN separation expertise lies the SSMB Sequential Simulated Moving Bed Chromatography Device, a state-of-the-art instrument meticulously designed for unparalleled precision and efficiency. we believe that the right tools can make all the difference.

Our innovative approach begins with a special pretreatment of the solution. The molybdenum in the solution is selectively adsorbed onto our specially designed resin, leaving the tungsten in the post-adsorption solution. This method ensures a simple, efficient, and effective separation of the two metals, setting a new industry benchmark.

Sunresin's premium resins excel in eliminating impurities from the leaching solution, marking a significant reduction of TOC (residual P204, P507, sulfonated coal oil, etc.), COD (Chemical Oxygen Demand). This method is not only efficient but also environmentally conscious, ensuring no new impurities are introduced. The result? Enhanced economic value and benefits.

Advantages of Resin Adsorption: -Environmental-friendly and low energy consumption, operating under ambient temperature and pressure conditions. -Sunresin's chelating resin demonstrates excellent performance in the extraction of precious metals such as cobalt, vanadium, platinum, palladium, and gold. It not only achieves the requirements for the wastewater maximum content of metals but also enables the recovery of high-concentration metal salt solutions. -The resin has very high adsorption capabilities across different concentrations of mother liquor, with minimal impact from the ionic form of platinum and palladium. It operates stably under various pH conditions, facilitating the recovery of precious metals. In the field of platinum catalyst recovery in the pharmaceutical industry, this resin series offers high processing precision and large adsorption capacity compared to traditional recovery processes.

In concentrated hydrochloric acid, metal ions mainly exist in the form of complex anions. LSC series ion exchange resins can effectively remove iron ions and also remove other metal ions to varying degrees. Contaminated hydrochloric acid passes through a special ion exchange resin, and the exchange process capture the iron thanks to the very high selectivity. Once the LSC series ion exchange resin is saturated with iron ions, it can be regenerated with deionized water (distilled water). After regeneration, the ion exchange resin is restored to its original state and can be repeatedly used for exchange and regeneration.

The SSMB sequential simulated moving bed chromatography system is an intermittent sequential operation simulated moving bed that combines the Monojet® series jetted particle chromatography fillers. Through the ingenious combination of equipment and control programs, it simulates the movement of the filler layer, adopts different operating modes of intermittent feeding and discharging with different sequences and programs, and adds separation ports that can be used for individual components to flow out, achieving the batch separation of 2-3 components. It has been successfully applied to the separation and purification of products such as sugar alcohols, amino acids, organic acids, and pharmaceutical intermediates.
