Analysis of Waste Lubrication Regeneration Process by Solvent Refining Method
Waste lubricating oil regeneration process Over the years, both developed and developing countries have accumulated rich experience in waste oil recycling. At present, the main processes for recycling waste oil into applicable base oils are: 1. acid white clay process; 2. vacuum distillation-solvent Refining process; 3. solvent extraction-flocculation process; 4. molecular distillation process; 5. hydrogenation process; 6. membrane separation process. According to the difference between waste oil treatment processes at home and abroad, the regeneration process of waste lubricating oil can [...]
