The application of centrifuge in petroleum sulfonate production
In the quality standard of petroleum sulfonate, the content of disorderly chemical substances is one of the key index values for the inspection of sulfonate, and becomes the key factor for the production of sulfonate. How to reasonably separate the disordered chemical substances from crude petroleum calcium sulfonate, and how to completely separate the acid residue of micro particles from acid-base oil, has become an obstacle to improve the quality of petroleum sulfonate series products. The application of high-speed suction filtration technology has solved this problem in essence. Gravity separation technology gravity separation is the application of the relative density of each component in the combined solution is not the same, the heavy phase moves down to the bottom of the vessel, while the light phase floats on the surface, and the middle of the light and heavy phase is converted into a certain page. The higher the relative density difference, the faster the separation rate. In the process of sulfonate processing, gravity separation is only to remove the slag of large particles. The relative density of acid residue and calcium residue is about 0.4g/cm3 higher than that of oil. The smaller acid slag and calcium slag are floating in the product oil in the form of opacification liquid, which is difficult to separate from the product oil with the help of relative density difference, and can only be separated with the help of mechanical equipment.
When the vessels equipped with binding fluid revolve around their own center line, because the two phases of the binding fluid are different in weight, they suffer from different centripetal force, and the heavy phase in the binding fluid suffers great centripetal force. Petroleum sulfonate, as a lubricant additive, has a relatively late development trend in China, and it was only in the 1950s that small-scale production was started, In the middle and late 80's, the technology of sulfonate formation was introduced from England, which made the type of production very different from overseas, but there were still some differences in quality. According to the source of raw materials, sulfonates are divided into petroleum sulfonates and sulfonates. Due to various factors such as environmental protection, the chemical plants that used to produce sulfonates, the additive plant of Jinzhou Petrochemical Company and the Jinta enterprise of Karamay were shut down in turn. High tech enterprises increase the production of petroleum sulfonic acid. Due to the sulfur content of waste gas processing technology, acid residue non harm treatment processing technology, spray film sulfonation reaction and other excellent technologies with independent patent rights, it has become the only flat production and manufacturing enterprise of petroleum sulfonate in China. Its petroleum sulfonate product series mainly include: low base value calcium petroleum sulfonate (T101), medium base value calcium petroleum sulfonate (T102), high base value calcium petroleum sulfonate (T103) Barium petroleum sulfonate (T701), magnesium petroleum sulfonate (t705), low molecular weight sodium petroleum sulfonate, high molecular weight sodium petroleum sulfonate, petroleum sulfonic acid and water-soluble emulsified oil, etc.
