Chemical raw materials and chemical products manufacturing industry

The general name of social production departments that use chemical processes to produce various chemical products needed by the economy and society.

Chemical raw materials and chemical products manufacturing industry, customarily called "chemical industry", refers to the general name of social production departments that use chemical processes to produce various chemical products needed by the economy and society. The national standard code of chemical raw materials and chemical products manufacturing industry is 26, which plays an important role in the national economy.

According to the industry classification standard of National Bureau of Statistics (GB/T 4754-20 17), chemical raw materials and chemical products manufacturing industry includes seven sub-industries, including basic chemical raw materials manufacturing, fertilizer manufacturing, pesticide manufacturing, coating, ink, pigment and similar products manufacturing, synthetic materials manufacturing, special chemical products manufacturing and daily chemical products manufacturing.

Basic chemical raw material manufacturing industry

According to the manufacturing classification standard of the National Bureau of Statistics, the basic chemical raw material manufacturing industry includes five sub-industries: inorganic acid, inorganic alkali, inorganic salt, organic chemical raw material manufacturing industry and other basic chemical raw material manufacturing industries. The main products include "three acids and two bases" (sulfuric acid, nitric acid, hydrochloric acid, caustic soda, soda ash), calcium carbide, trienes, triphenyl, acetylene, naphthalene and other products. The upstream of basic chemical raw materials are mainly crude oil, natural gas, coal, crude salt and other commodities, which are mainly used as intermediate inputs for the production of downstream derivative chemical products.

China is a major producer of basic chemical raw materials in the world. By the end of 20 1 1, the output of soda ash, caustic soda, sulfuric acid, calcium carbide, methanol, terephthalic acid and PVC in China ranked first in the world. However, the structural and unsustainable contradictions faced by China's basic chemical raw material manufacturing industry are increasingly prominent. Mainly reflected in two aspects: First, the problem of overcapacity of bulk products is prominent. During the 11th Five-Year Plan period, the operating rates of calcium carbide, ethanol, dimethyl ether and acetic acid were only 60.9%, 40%, 25% and 6 1% respectively. Second, the cost of resources and environment is too high. The manufacturing of basic chemical raw materials is a traditional industry with high energy consumption and high pollution. Among the key monitoring enterprises of waste water and waste gas announced by the state, basic chemical raw material production enterprises account for more than one fifth. 20 13 countries have repeatedly improved the access conditions of basic chemical raw materials industries and made great efforts to eliminate backward production capacity. However, due to factors such as steady economic growth and insufficient private capital investment channels, the basic pattern of excessive enterprises and overcapacity has not changed.

From the demand level, there is no obvious regional and seasonal difference in the consumption of basic chemical raw materials in China, but there is a certain periodicity. The performance of an enterprise is usually a performance change, such as gross profit margin, growth rate of industrial sales output value and profit growth rate ahead of macroeconomic changes. During the "Twelfth Five-Year Plan" period, China will continue to intensify structural adjustment and guide the basic chemical raw material manufacturing industry to optimize and upgrade. According to the Twelfth Five-Year Development Plan for Petroleum and Chemical Industry, during the Twelfth Five-Year Plan period, China will implement strict total control measures for some industries with overcapacity, and strive to control the production capacity of caustic soda, soda ash, methanol and calcium carbide at 36.5438+00,000 tons/year, 30,000,000 tons/year, 40,000 tons/year and 28,000,000 tons/year respectively. Encourage basic chemical raw material enterprises to make great efforts to adjust the product structure and make breakthroughs in the production of high-end petrochemical products such as bisphenol A, polyethylene polyamine, adipic acid, aliphatic and cycloaliphatic diisocyanate (ADI) and propylene oxide (hydrogen peroxide method). At the same time, enterprises are encouraged to implement waste heat and pressure utilization, oil conservation and energy system optimization projects, reduce emissions and improve resource utilization efficiency.

Fertilizer manufacturing

Fertilizer manufacturing industry includes six sub-industries: nitrogen fertilizer, phosphate fertilizer, potash fertilizer, compound fertilizer, organic fertilizer, biological fertilizer and other fertilizer manufacturing. Because the proportion of organic fertilizer, biological fertilizer and other fertilizers is less than 2%, the fertilizer manufacturing industry usually refers to the fertilizer industry dominated by nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer and compound fertilizer. The upstream of chemical fertilizer industry is mainly coal, natural gas, potash ore, phosphate rock and other commodities, 90% of which are used for agriculture and 10% for industry. Among them, the application ratio of agricultural chemical fertilizer N, P and K is 1: 0.36: 0. 18.
