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 [...]

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 process The 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 [...]

Talking about the process of filtering oil in the workshop by vacuum filter

The working principle is simple and the effect is remarkable. Inside it, there is a rotor with twin nozzle, which only needs the pressure generated by the oil to provide its driving force. After the equipment is opened, the oil in the tank is sent to the rotor through the pump. After the oil is filled with the rotor, the oil nozzle is sprayed along the lower part of the disc, which produces the driving force to make the [...]

The filter plate and filter frame of the oil filter are made of cast iron or polypropylene

The ordinary oil filter consists of a primary filter, an oil pump and a filter. The primary filter is a cylindrical metal mesh, which prevents the larger solid particles in the impure oil from entering the oil pump. Oil pumps are usually gear pumps, conveying pure oil into the filter. The filter device is a small manual compression plate and frame filter press. Special filter paper is used as filter medium. The impure oil enters the plate and frame [...]

Vacuum filter oil filter common faults and solutions analysis and oil filter operation points

Common problems and elimination methods of vacuum oil filter: Vacuum oil filter precautions 1. The power must be connected to the ground before it can be operated. 2. When operating, pay attention to the direction of rotation of the motor, in accordance with the direction of the arrow. 3. When there is no oil circulation, do not start the heater, otherwise the heater will burn out and the weight will be fried. 4. Before draining oil, all valves of the oil outlet pipe must [...]
