Sep-Pro - Lube Oil Re-Refining Systems

Sep-Pro Lube Oil Re-Refining systems distill (atmospheric and vacuum) used lube oil that generally contains light ends, water, asphaltene, and trace organic acids. The bottoms enter a liquid-liquid extraction system where the remaining asphaltenes and aromatics are extracted using a polar solvent. The system uses distillation to recover the solvent from the raffinate and extraction phases of the extraction column.
