Classification and Refining Of Solvents In The Waste Oil Recycling Industry

Solvent refining refers to a process of removing impurities and non-ideal components contained in a raw material (or semi-finished product) by extraction. It is also a common process for waste oil regeneration. Solvent The term broadly refers to an excess of the component contained in a homogeneous mixture. In a narrow sense, a liquid that does not undergo any change in chemical composition and that dissolves other substances (generally referred to as solids), or a liquid that chemically reacts with a [...]

How to properly dispose of used engine oil?

The oil, that is, the lubricating oil of the engine, can lubricate, clean, cool, seal, reduce, rust, and prevent the engine. After a long period of use, the oil will produce deposits, sludge, and paint film, which will cause deterioration. These substances are deposited on the surface of the friction member, the passage of the lubricating oil, and the filter, which may cause various malfunctions of the machine. With the continuous advancement and rapid development of China's industry, the holdings of [...]

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 [...]
