According to Wang Wentang, secretary-general of the Chemical Energy Conservation Association, the energy consumption of the petrochemical industry in China in 2009 was mainly concentrated on chemical raw materials and chemical products manufacturing, petroleum processing, coking, and nuclear fuel processing industries. Among them, the energy consumption of chemical raw materials and chemical products manufacturing industry reached 28641 million tons of standard coal, the energy consumption of petroleum processing, coking, and nuclear fuel processing industries reached 148,626,800 tons of standard coal, and the energy consumption of oil and gas extraction industry reached 32,795,400 tons of standard coal. The energy consumption of the rubber products industry was 8,931,100 tons of standard coal.
The chemical industry's fertilizer manufacturing, basic raw material manufacturing and organic chemicals account for about 55% of the total energy consumption of the petrochemical industry. Among them, 40% of energy is used for nitrogen fertilizers, caustic soda (including polyvinyl chloride), calcium carbide, yellow phosphorus, soda ash, ethylene and other products.
Since the “Eleventh Five-Year Plan†period, the energy consumption of most key energy-consuming products in the petrochemical industry has continuously declined. Compared with 2006, standard oil consumption per ton of crude oil processed in 2009 fell by 5.31%; standard oil consumption per ton of ethylene decreased by 5.79%; standard ammonia consumption per ton of synthetic ammonia decreased by 3.82%; consumption of caustic soda per ton The standard coal dropped 13.89%; the soda consumption per ton of product decreased by 17.2%; the consumption of calcium carbide per ton of product decreased by 10.78%; and the consumption of yellow phosphorus per ton of product decreased by 0.52%.
The Energy Savings Progress Report also analyzes the energy-saving potential of key energy-consuming products in 2010. If crude oil processing volume reaches 400 million tons in 2010, about 4.76 million tons of standard oil will be saved compared to 2006; ethylene production will reach 13 million tons, which will save 610,000 tons of standard oil than in 2006; and the output of synthetic ammonia will reach 52 million tons, which is more than 2005 savings. 5.2 million tons of standard coal; production of caustic soda reached 20 million tons, which saved 1.94 million tons of standard coal than in 2005; production of soda ash reached 20 million tons, 220,000 tons of standard coal was saved compared to 2005; output of calcium carbide reached 15 million tons, compared with 2005 Save 1.62 million tons of standard coal; yellow phosphorus production reached 850,000 tons, 300,000 tons of standard coal than in 2005.
According to the progress report on energy conservation, from 2000 to 2009, the country’s industrial energy consumption increased by 9.91% annually, the petrochemical industry’s energy consumption increased by 7.72% annually, and the petrochemical industry’s energy consumption growth rate was lower than the national industrial energy consumption growth rate by 2.19 percentage points. . Nevertheless, the current energy consumption of the petrochemical industry still accounts for 1/5 of the total industrial energy consumption in the country. The petrochemical industry faces enormous challenges in energy conservation and emission reduction.
For energy conservation, 70% is through structural adjustment and 30% through technological advancement. Wang Wentang believes that the favorable factors for energy conservation and emission reduction in the petrochemical industry include: during the “12th Five-Year Plan†period or longer, the national energy conservation policy environment and policy will continue to strengthen; China has made a commitment to carbon emission reduction for the international community. Energy conservation is a requirement for the development of a low-carbon economy; energy-saving management measures will be gradually implemented; new energy-saving technologies are emerging and applied in a timely manner; on the basis of the assessment of the energy conservation of enterprises in the “Eleventh Five-Year Planâ€, the “Twelfth Five-Year Plan†period The assessment of the energy consumption of enterprises will be more scientific and more rigorous; the importance of energy conservation has been recognized by more and more people in charge of the company and has become a conscious action of the company.
Unfavorable factors include: energy saving has not yet become the conscious action of employees; energy saving target assessment needs further improvement; technical and economic evaluation of energy-saving projects needs to be improved; energy supply and demand balance or sufficient energy supply, energy supply prices are lower; Weak and so on. It is understood that this is the first report issued by the Chemical Energy Conservation Association on the progress of energy conservation in the petrochemical industry and will be published once a year.
Petrochemical Industry Releases Progress Report on Energy Savings Caustic soda tons of coal consumption 13.89%
The China Chemical Industry Energy-saving Technology Association has for the first time released the "Report on Progress of Energy Conservation in China's Petroleum and Chemical Industry." Statistics show that since 2000, the ratio of energy consumption in the petroleum and chemical industries to industrial energy consumption has declined year by year. In 2009, the petrochemical industry consumed 47.125 million tons of standard coal, which accounted for 15.2% of the country's total energy consumption. It accounted for 22.6% of industrial energy consumption, a decrease of 4.47 percentage points from 2000.
