Introduction of 5 kinds of waste oil regeneration technology

1.  Sulfuric acid-white clay refining processThe sulfuric acid-white clay refining process is the first process to be used in the research of waste oil regeneration technology at home and abroad, in which a large amount of sulfuric acid and white clay are used to treat waste oil. The waste oil is pretreated (pre-flash or vacuum distillation) to separate water and light hydrocarbons, and concentrated sulfuric acid (10%~15%) is added to the dehydrated waste oil, such as colloidal, asphaltene, oxidation [...]
