Description
Technical Field

[0002] Ester base oil refers to a natural substance containing an ester group in its molecular structure. This type of oil can be found in animal and plant oils and fats. Ester base oil is one of the five types of base oils. Ester oil can dissolve additives well, has strong polarity, can be adsorbed on the metal surface, and can form a protective oil film before starting, which has a role in maintaining and regulating rubber elasticity. At the same time, it has a high flash point and low evaporation loss, which is very helpful in alleviating engine oil consumption. The production process of ester base oil includes deacidification, decolorization, deodorization and refining, etc., and usually requires distillation processing in a distillation tower. Since it is extracted from animals and plants, the bottom liquid generally contains incompletely reacted raw materials, by-products, catalyst residues and some small solid impurities.

Through multiple groups of branch pipes and annular cavities, it can reduce the impact on the original products in the distillation tower, making the operation of the distillation tower more stable.
