ABSTRACT:
A compact solvent reprocessing system for use in a limited physical area. Solvents to be reprocessed is contacted by deionized water in a water wash column and delivered to a distillation column where waste solvent is separated from materials that boil at a higher temperature than the waste solvent. Distilled solvent is delivered to a drying column and final filters for removal of any other foreign materials. The modular solvent reprocessing system to reclaim/recycle high purity solvents on-site at a manufacturing facility. A system includes a pumpless pressurized tank solvent transfer units, storage tanks, liquid-liquid extraction column, distillation columns, submicron filtration units, and water and acid adsorption columns arranged as necessary to produce ultra-high purity solvents from waste solvent streams. The systems are packaged in modular assemblies with secondary containment to meet U.S. EPA requirements.
