Problems solved by technology

Among them, acid-base refining produces a large amount of waste acid and waste lye, which will cause serious environmental pollution; the solvent extraction desulfurization process consumes a lot of energy and the oil yield is low; the adsorption capacity of the adsorbent in the adsorption method is small, and it needs to be regenerated frequently
[0004] Other non-hydrogenation desulfurization technologies are still in the experimental stage. Among them, the application prospects of biological desulfurization, oxidation desulfurization and light and plasma desulfurization are very attractive, and they are effective methods to realize the production of clean fuel oil in the future. Without large-scale industrial production, it is a complicated process to reduce the sulfur content in fuel oil and reduce air pollution. Therefore, various factors should be considered during implementation, and the reliability of technology should be improved to achieve the best economic and environmental benefits.

Description

technical field [0001] The invention relates to the field of petroleum desulfurization, in particular to an intelligent crude oil desulfurization equipment. Background technique [0002] There are hundreds of sulfur-containing hydrocarbons in petroleum, and more than 200 of them have been verified and confirmed in structure. These sulfur-containing hydrocarbons are distributed in various distillates in the process of petroleum processing to varying degrees. In view of the wide application of petroleum products in production and life, the removal of harmful sulfur is very important for production practice. [0003] At present, non-hydrogenation desulfurization methods, acid-base refining, solvent extraction and adsorption desulfurization are mainly used in industry. The above-mentioned desulfurization methods all have defects and deficiencies. Among them, acid-base refining produces a large amount of waste acid and lye, which will cause serious environmental pollution; the s...
