The QY Series ("QingYuan"/"Clear Source") solution purification equipment is a range of high-efficiency solution purification systems independently developed, designed, and manufactured by NENGJING, specifically optimized for the characteristics of the JC Series solvents. This series covers various mainstream purification technologies including ion exchange, electrodialysis, vacuum distillation, and activated carbon adsorption, effectively addressing different types of pollutants in solutions and adapting to diverse complex operating conditions. Adopting a modular design concept, QY Series equipment can be flexibly integrated into acid gas separation systems for turnkey delivery or easily connected to existing process sections. Furthermore, the equipment supports online purification during continuous production and offline processing during shutdowns, offering true plug-and-play flexibility and efficiency. In actual production, the accidental introduction of exogenous pollutants often affects acid gas separation performance. As a key link in NENGJING's purification system, the QY Series effectively avoids the extra costs associated with complete solvent replacement, genuinely helping customers reduce costs, increase efficiency, and ensure long-term stable production.
