Organic solvents are widely used in the pharmaceutical process. Due to their large usage, complex waste solvent properties, impurities, and high requirements for recovery quality, they result in high solvent loss, low recovery rates, and significant pollution. As a result, the solvent consumption in China's pharmaceutical process is much higher than the international average, and emissions that do not meet standards have become a major issue in environmental protection. Through the research and development of modified adsorbents and concentrated materials, our company has established a mature solvent recovery process and technology, especially achieving high recovery efficiency in the field of solvent recovery with low and medium concentration content.
