What does petrochemical industry mean?

Petrochemical (English: petrochemical), also known as petrochemical industry, refers to the field of producing chemicals from petroleum in chemical industry, which also includes natural gas chemical industry in a broad sense. As a new industry, the petrochemical industry of China Petrochemical Co., Ltd. was formed with the development of petroleum refining industry in the 1920s and grew up during the Second World War (see History of Petrochemical Development). After the war, with the rapid development of petrochemical industry, the production of a large number of chemicals has changed from traditional raw materials of coal and agricultural and forestry products to raw materials of oil and natural gas. Petrochemical industry has become a pillar industry in the chemical industry and occupies a very important position in the national economy. Petrochemical products, mainly gasoline, kerosene, diesel, heavy oil and natural gas produced by petroleum refining, are the main suppliers of major energy sources at present. China produced 80 million tons of fuel oil in 1995. At present, the world oil and gas consumption accounts for about 60% of the total energy consumption; Because China uses a lot of coal, the consumption of oil is less than 20%. The energy provided by petrochemical industry is mainly used as fuel for automobiles, tractors, airplanes, ships and boilers, and a small amount is used as civil fuel. Energy is a factor that restricts the development of China's national economy. The energy consumed by petrochemical industry accounts for about 8.5% of the total energy, so energy consumption should be continuously reduced.

Which belong to the petrochemical industry?

Petrochemical industry is a pillar industry in China. The petrochemical industry has a long production line and wide coverage. China Petrochemical Group alone has nearly 6,000 kilometers of crude oil, refined oil and natural gas pipelines and 24,000 gas stations. Petrochemical enterprises have oil fields, oil production plants, refineries, chemical plants, oil depots, gas stations and oil (gas) pipelines all over the country, including cities, towns, stations, docks, hotels and thousands of households. The production process includes oil and gas exploration, oil and gas field development, drilling engineering, oil production engineering, oil and gas gathering and transportation, crude oil storage and transportation, petroleum refining, chemical production and oil product sales. The production of more than 3,000 kinds of petrochemical products, such as gasoline, kerosene, diesel oil, lubricating oil, chemical raw materials, synthetic resins, synthetic fibers and fertilizers, is closely related to people's food, clothing, housing and transportation. In 2000, China Petrochemical Industry produced 654.38+63 million tons of crude oil and processed 265.438+63 million tons of crude oil. China's three major petroleum and petrochemical companies-China Petrochemical, China Petroleum and China Offshore Oil Group-have fixed assets of more than 600 billion yuan and more than 2 million employees. The petrochemical industry plays an important role in the development of China's national economy. Petrochemical industry is also a high-risk industry with its own characteristics. 1 The materials involved in petrochemical production are very dangerous, and the probability of fire, explosion and group casualties is high. Raw materials, semi-finished products and finished products of crude oil, natural gas, gasoline, liquid hydrocarbons, ethylene, propylene and other auxiliary materials used in petrochemical production. , mostly flammable and combustible substances. Once leaked, it is easy to form explosive mixture, which will cause combustion and explosion. Many substances are highly toxic and toxic, such as benzene, toluene, sodium cyanide, hydrogen sulfide, chlorine and so on. Improper disposal or leakage of these materials may easily lead to casualties; Various corrosive acids and bases, such as sulfuric acid, hydrochloric acid, caustic soda, etc. It is also used and produced in petrochemical production, and the possibility of corrosion problems of equipment and pipelines is high; Some materials also have the characteristics of spontaneous combustion and explosive polymerization, such as organometallic catalysts and ethylene. The petrochemical production process is complex and the operating conditions are harsh, which is prone to sudden and catastrophic accidents. In the petrochemical production process, there are many physical and chemical processes and mass transfer and heat transfer unit operations, and some process control conditions are extremely harsh, such as high temperature, high pressure, low temperature and vacuum. For example, the temperature of steam cracking is as high as 1 100℃, while the temperature of some cryogenic separation processes is as low as-100℃; The polymerization pressure of high-pressure polyethylene reaches 350MPa, and the production pressure of polyester is only 1 ~ 2 mmhg. Especially in vacuum distillation, catalytic cracking, coking and many other processing processes, the material temperature has exceeded its self-ignition point. These harsh conditions put forward strict requirements for the manufacture, maintenance and personnel quality of petrochemical production equipment, and any slight mistake may lead to disastrous consequences. 3. The factory scale is large, the production scale is large, and the continuity is strong. Individual accidents affect the overall situation. Petrochemical production facilities are large in scale, single series and high in automation. As long as a certain part or link fails or operates incorrectly, it will affect the whole body. Petrochemical production plants are developing to large scale, and the processing capacity of a single plant is expanding. For example, the capacity of the conventional vacuum distillation unit has reached100000 t/a, the maximum capacity of the catalytic cracking unit is 8 million t/a, and the capacity of the ethylene unit will reach 900000 t/a. Large-scale units will increase the storage of dangerous substances in the system and increase risks. At the same time, the petrochemical production process has a strong continuity. In the field of some large-scale integrated devices, devices are interrelated and the material supply is tight. The product of one device is often the raw material of another device, and local problems often affect the overall situation. 4. The equipment is technology-intensive and capital-intensive, causing heavy property losses in the accident. Due to the complex process, high equipment manufacturing and installation costs and intensive equipment funds, once petrochemical equipment has an accident, it will cause huge losses. Due to the intensive capital of petrochemical equipment, the property loss caused by the accident is huge.

What industry does the petrochemical plant belong to?

Petroleum belongs to "petroleum processing, coking and nuclear fuel processing industry"

Chemical industry belongs to "chemical raw materials and chemical products manufacturing industry"

Both belong to "manufacturing"

What does petrochemical industry mean?

Petrochemical industry Petrochemical industry is referred to as petrochemical industry for short. Petrochemical industry is a basic industry, which provides supporting services for agriculture, energy, transportation, machinery, electronics, textiles, light industry, architecture, building materials and other industries and people's daily life, and occupies a decisive position in the national economy. It is an important part of chemical industry, occupies an important position in the development of national economy and is one of the pillar industries in China. Petrochemical refers to the processing industry that produces petroleum products and petrochemical products with petroleum and natural gas as raw materials. Petroleum products, also known as petroleum products, mainly include various fuel oils (gasoline, kerosene, diesel oil, etc. ) and lubricating oil, as well as liquefied petroleum gas, petroleum coke, paraffin, asphalt, etc. The process of producing these products is often called petroleum refining. Petrochemical products are obtained by further chemical processing of crude oil provided by refining process. The first step in the production of petrochemical products is to crack raw oil and gas (such as propane, gasoline, diesel oil, etc.). ) to produce basic chemical raw materials represented by ethylene, propylene, butadiene, benzene, toluene and xylene. The second step is to produce all kinds of organic chemical raw materials (about 200 kinds) and synthetic materials (plastics, synthetic fibers and synthetic rubber) from basic chemical raw materials. The production of these two-step products belongs to the category of petrochemical industry. Continuous processing of organic chemical raw materials can produce more kinds of chemical products, which usually does not belong to the scope of petrochemical industry. In some data, synthetic ammonia, urea and even nitric acid extracted from natural gas, light gasoline and heavy oil are also listed in the petrochemical industry.
