Background of the project
Petrochemical refers to the processing industry that uses oil and natural gas as raw materials to produce petroleum products and petrochemical products. Petrochemical products are obtained by chemical processing of the raw oil provided by the refining process. The first step in the production of petrochemical products is to crack raw oil and gas (such as propane, gasoline, diesel, etc.) to generate basic chemical raw materials represented by ethylene, propylene, butadiene, benzene, toluene, and xylene. The second step is to produce more than 200 kinds of organic chemical raw materials and various synthetic materials from basic chemical raw materials.
In addition to the petrochemical industry, petrochemical-dependent industries such as chemical fertilizers, man-made fibers, synthetic resins and plastics, paints, cleaning supplies, man-made fiber textiles, knitting, and rubber products are also closely related to people's food, clothing, housing, lines are closely related. About 70% of the hardware parts of precision products, such as parts, casings, tires, chemicals, etc., come from the petrochemical industry.
dangerous gas
The materials involved in petrochemical production are dangerous, and the probability of fire, explosion, mass death and injury accidents is high. Petrochemical production, from raw materials to products, including semi-finished products, intermediates, various solvents, additives, catalysts, reagents, etc. in the process, most of which are flammable and combustible substances, as well as explosive substances such as crude oil, natural gas, gasoline , liquid hydrocarbons, ethylene, propylene, etc. Most of them exist in the state of gas and liquid, which are easy to leak and volatilize. Many materials are highly toxic and highly toxic substances, such as benzene, toluene, sodium cyanide, hydrogen sulfide, chlorine, etc., which are improperly disposed of or leaked. , which can easily lead to casualties. In the petrochemical production process, a variety of highly corrosive acids and alkalis are also used and produced, such as sulfuric acid, hydrochloric acid, caustic soda, etc., the possibility of equipment and pipeline corrosion problems is high; some materials also have the characteristics of spontaneous combustion and violent aggregation. Such as metal organic catalysts, ethylene, etc. Especially in the production process, the technological operating conditions are harsh, including high temperature, cryogenic temperature, high pressure, and vacuum. Many heating temperatures have reached or exceeded the spontaneous ignition point of the material. Once the operation is wrong or the equipment is in disrepair, fire and explosion accidents are very likely to occur. In addition, as far as the current technological level is concerned, in many production processes, the materials must be heated with an open flame; in addition, the daily equipment maintenance needs to be heated frequently. This constitutes a prominent contradiction, that is, the fear of fire, but also the use of fire, coupled with the large reserves of flammable and explosive substances in various enterprises and installations, once they are not handled properly, accidents will occur, and the consequences are unimaginable. Accidents have fully proved this point. In addition, in the production operating environment and construction sites, there are some harmful factors, such as industrial noise, high temperature, dust, rays and so on. These toxic and harmful factors will cause acute poisoning accidents, and will also increase over time, even under low concentration (dose) conditions, due to their combined effects, they will affect the health of workers and lead to various occupational diseases.
Program overview
The deadly threat in this industry lies in the leakage and combustion of explosive gas, which is always accompanied by the entire operation process of production and processing. Use multiple gas detectors to conduct real-time and on-site monitoring of enterprises and parks, install combustible and toxic gas detectors in gas leakage hidden danger areas, personnel work areas and gas storage areas, cooperate with alarm control cabinets, background data analysis, and data processing centers , which can better realize comprehensive monitoring, display and early warning in the monitoring area, thereby reducing fire and explosion accidents, avoiding casualties, and ensuring the property safety of enterprises and parks.
