Application of Screw Vacuum Pumps in Solvent Recovery
Solvent recovery is a critical process in industries such as chemical, pharmaceutical, petrochemical, and environmental protection. It involves recovering solvents from process streams or waste products for reuse, which helps in reducing costs and minimizing environmental impact. Screw vacuum pumps have become a preferred choice in solvent recovery systems due to their reliability, efficiency, and ability to handle various types of gases and vapors. This article discusses the application of screw vacuum pumps in solvent recovery, In the production of active pharmaceutical ingredients (APIs), the solvent crystallization process involves several critical steps: filtration, washing, and vacuum drying after crystallization. The moisture content of the material is generally around 20%, and the drying temperature should not exceed 80°C. After drying, the moisture content of the API must be reduced to below 0.5%. To remove the solvent from the material effectively, the pressu
