Solvent recovery is a form of waste reduction. In–process solvent recovery is used as an alternative to solvent replacement to reduce waste generation. Availability of equipment suitable for small operations, especially batch operations, make in–process recovery of solvents economically preferable to raw materials substitution
Solvent Recovery Vacuum Systems
Solvent recovery vacuum systems are used in many industries including chemical, pharmaceutical, metal powders, flavor and fragrance, and PET solid-state manufacturing.
Often, solvent recovery vacuum systems are used in conjunction with the following equipment:
Wintek has experience helping customer recover the following solvents, among others:
- isopropyl alcohol (IPA)
- mineral spirits
Generally, Wintek utilizes a liquid ring vacuum pump sealed with one of these high vapor pressure solvents to maximize recovery and reduce potential contamination or environmental concerns. This requires an extensive knowledge of how equipment such as boosters are affected when sealing a pump with a potentially high vapor pressure solvent, even when operating at deep vacuum.
