Hydrogen Sulfide in Crude Oil
Correlation analysis of hydrogen sulfide in crude oil
Crude oil has always been a crucial one in various mineral resources. Among them, the existence of hydrogen sulfide has far-reaching impact and is related to many fields.
On the one hand, hydrogen sulfide is highly corrosive. In the equipment used in crude oil extraction, such as YouTube, sucker rods, etc., long-term contact with crude oil containing hydrogen sulfide, the metal material is corroded and lost, resulting in a sharp reduction in the service life of the equipment. Even due to corrosion and perforation, crude oil leakage is caused, which not only wastes resources, but also endangers the surrounding ecological environment. And hydrogen sulfide is very toxic. In mining, transportation and refining sites, if it escapes in the air, the operator accidentally inhales it, which can cause respiratory discomfort, dizziness and other diseases in light cases, and life-threatening in severe cases, seriously threatening the personal safety of practitioners.
From its genesis perspective, one is derived from biochemical effects. During the formation of crude oil, microorganisms participate in the decomposition of organic matter. Some microorganisms with sulfate reduction ability use sulfate as an electron receptor to reduce it to hydrogen sulfide in a specific anaerobic environment. The second is related to thermochemical decomposition. Crude oil is buried deep in the ground. After high temperature and high pressure, some sulfur-containing organic compounds will undergo thermal decomposition reactions, resulting in hydrogen sulfide.
In order to deal with the problem of hydrogen sulfide in crude oil, there are various means. The first is the chemical removal method, by adding specific chemical agents, such as alcohol amines, which can chemically react with hydrogen sulfide to generate stable compounds to achieve the purpose of removal. The second is the physical separation method, which uses the difference in physical properties between hydrogen sulfide and crude oil, such as solubility, boiling point, etc., with the help of distillation, absorption and other processes to achieve the separation of hydrogen sulfide and crude oil.
In short, in-depth understanding of hydrogen sulfide in crude oil, effective prevention and control, safe and efficient operation of crude oil extraction, transportation, refining and other series of links, is of great significance.
