Sunresin Hydrogen Peroxide Purification Technology-Enhancing Efficiency, Safety, and Sustainability in Caprolactam Production
Hydrogen peroxide (H₂O₂) plays a crucial role as an oxidizing agent in caprolactam production — a key raw material for synthetic fibers and engineering plastics such as nylon and polyester. The purity of hydrogen peroxide directly determines the quality and efficiency of caprolactam production.
In conventional industrial production, hydrogen peroxide is typically produced via the anthraquinone process. While mature and reliable, this method often introduces various impurities, including organic substances such as anthraquinone derivatives, esters, alcohols, phenols, and ketones. These impurities can significantly reduce the efficiency and lifetime of ion exchange resins used in subsequent processes, lower the purity of caprolactam products, and increase the environmental burden due to the difficulty of degrading anthraquinone compounds.
Challenges in Traditional Purification Systems
Traditional hydrogen peroxide purification often relies on fixed-bed adsorption systems, which suffer from:
- Low resin utilization and efficiency
- Long downtime and high operating costs
- Complex structures prone to leakage and maintenance issues
- Difficulties in maintaining product consistency across large-scale operations
With increasing global emphasis on cleaner and more sustainable chemical processes, there is a strong demand for a safer, more efficient, and environmentally friendly hydrogen peroxide purification solution.
Sunresin’s Innovative Continuous Purification Solution
Building on years of expertise in adsorption and separation technology, Sunresin developed an innovative continuous hydrogen peroxide purification process that combines multi-channel valve systems with specialized purification resins.
This advanced system provides several key advantages:
1.Continuous and Automated Operation
Through synchronized control of multiple columns and automatic switching valves, the adsorption, washing, replacement, and desorption steps are carried out continuously — enabling stable, uninterrupted operation throughout the year.
2.High Resin Utilization and Cost Efficiency
The new process improves resin utilization by over 20%, increases adsorption efficiency by more than 40%, and reduces overall production costs by 30–50% compared with conventional fixed-bed systems.
3.Enhanced Safety and Environmental Performance
The system adopts a fully sealed and segmented flow design, effectively preventing material mixing or leakage. This ensures higher operational safety and reduces wastewater discharge, aligning with the principles of green manufacturing.
Driving Sustainable Chemical Manufacturing
Sunresin’s hydrogen peroxide purification technology represents a significant step forward in promoting green, efficient, and safe production in the chemical industry. By combining advanced materials, process design, and intelligent system engineering, Sunresin helps chemical producers enhance both economic and environmental performance.
The technology has demonstrated excellent scalability and stability in industrial applications, making it particularly suitable for caprolactam production and other fine chemical processes where product purity and operational safety are critical.
