Petrification

　　The petroleum and petrochemical industry generally refers to the processing industry that uses petroleum and natural gas as raw materials to produce petroleum products and petrochemical products. The field of petroleum petrochemical is very broad, many products, is an important component of chemical industry, plays an important role in the development of national economy, is one of the pillar industry of our country.Petrochemical industry is the main supplier of energy, is one of the pillars of the material industry, and has promoted the rapid development of Chinese agriculture. Petrochemical products are also closely related to people's life, providing a variety of daily necessities for human beings, not only add colorful colors to the world, but also make people enjoy a high standard of life with plenty of clothes and food, comfort and convenience.

　　There are many kinds of poisonous and harmful gases in the process of petroleum and petrochemical production, which are widely distributed and have potential dangers of fire, explosion and poisoning. The poisonous and harmful gases in the process of petroleum and petrochemical production include hydrogen sulfide, chlorine, carbon monoxide, ammonia, benzene vapor and so on.Especially in recent years, with the change of crude oil types, the sulfur content in crude oil increases, and the content of hydrogen sulfide in the production medium is also increasing, which can reach more than 80%, and the risk of hydrogen sulfide poisoning is also increasing.Hydrogen sulfide is mainly distributed in dry gas, gas, acid gas, sulfur-containing sewage, crude gasoline, diesel oil, liquefied gas, residual oil, condensate oil and other media in refining and chemical production units. The parts prone to leakage are dehydration port, sampling port, condensate discharge port, air outlet, metering instrument interface, etc.；Ammonia mainly exists in sewage stripping equipment, ammonia storage tank area, chemical fiber sewage treatment equipment, etc. Benzene vapor mainly exists in catalytic reforming unit, aromatics extraction unit and storage tank area. Carbon monoxide mainly exists in boiler, heating furnace, combustion chamber, flue gas. Therefore, it is of great practical significance to strengthen the detection of poisonous and harmful gases in petroleum and petrochemical industry.
