Production of a variety of medium and high-grade internal combustion engine oil, gear oil essential base oil

The pilot and pilot processes are batch-type, and the industrial plants are continuous, with slight differences. In industrial production, the settling time can be appropriately extended on the pilot scale (ie, the feed amount is reduced). In order to eliminate the error, the settling time is about 10h (feed amount 20.97t/10h). The white soil refining process produces the second line, the minus three lines, and the reduced four line base oil. The process is not only feasible, but also proved to be successful. The process is simple, the operation is convenient, the investment is saved, and the application is convenient. The process has wide adaptability to raw materials when producing second-line, minus-three-line, automobile lubricating oil and four-line base oil. Nanyang Oil, Xijiang Oil, Jianghan Oil and Luning Oil can be produced normally, and can reflect the process protection. The advantage of sulfur denitrification can significantly improve the induction period of the rotating oxygen bomb of the base oil, and even meet the requirements of the MVIS base oil standard, improve the quality of the base oil, and facilitate the upgrading of the lubricating oil product.
MVI125/140BS is an essential base oil for the production of various medium and high grade internal combustion engine oils and gear oils. The residual oil produced by Jingmen Petrochemical Hydrogen Replenishing and Refining produces poor oxidation stability. The induction period of rotary oxygen bomb is only 5060min, which does not meet the requirements of MVI base oil standard, which hinders the upgrading of diesel engine oil and lubricant investment gear oil. It is a great pity that the residual oil cannot be industrially produced or liquid phase denitrification. In order to improve the quality grade of Jingmen Petrochemical MVI125/140BS base oil, eliminate the bottleneck restricting the production of lubricating oil, and supplement the liquid nitrogen denitrification-white earth refining process, industrial trial production must be carried out as soon as possible, which is conducive to the promotion of Jingmen Petrochemical.
