Comprehensive Consumption Decrease Energy-saving Technology Equipment Application to be Follow-up Policy

Despite being separated from the "Bird's Nest", Sun Weishan, deputy secretary-general of the China Petroleum and Chemical Industry Association, did not have time to watch the match. He is preparing for the largest ever gathering in the petrochemical industry.
Petroleum and chemical industries are the basic raw material industries that consume a lot of energy and emit large amounts of waste, and face enormous pressures for energy conservation and emission reduction. Sun Weishan introduced that in order to summarize the achievements made by the petrochemical industry in energy conservation and emission reduction, to publish and display new energy-saving emission reduction technologies and new equipment in the industry, the petrochemical association will hold a national conference on energy conservation and emission reduction in the petroleum and chemical industry on October 30th. Promote the industry's energy conservation and emission reduction work in depth.
Standards, technologies and management advance simultaneously
“With the implementation of various energy-saving and emission-reduction measures, the comprehensive energy consumption per unit of major energy-consuming products in the oil and chemical industry in the first half of the year has declined significantly,” said Sun Weishan.
According to the latest data, the comprehensive energy consumption per unit of added value in the petrochemical industry fell by 1.58% in the first half of this year, and the chemical industry decreased by 4.76%. The comprehensive energy consumption of some high-energy-consuming products per unit product continued to decline compared to the same period of last year. For example, the comprehensive energy consumption per unit of ethylene decreased by 2.81% over the same period of last year, the soda ash decreased by 6.51%, and the synthetic ammonia decreased by 2.32%.
“The petrochemical companies pay full attention to energy conservation and emission reduction. With the in-depth implementation of this work, specific policies have been introduced one after another. At present, the importance of enterprises in energy conservation and emission reduction has been increased to an unprecedented degree.” Wang Wentang, Secretary-General of China Chemical Energy Technology Association Say.
"A concrete embodiment is that at the exchange meeting in the industry, energy-saving and emission-reduction technologies have become one of the central contents of technological exchanges," said a person from the petrochemical association.
According to the person in charge, energy-saving management measures of key petrochemical energy-consuming enterprises, such as the enhancement of internal institutions and the matching of measuring instruments, have made great progress. This laid a solid foundation for the development of energy conservation work and also provided relatively reliable material conditions for completing the energy conservation goals set out by the National Development and Reform Commission's “Implementation Plan for Energy Use Status Report System of Key Energy-using Units”.
At the same time, in order to promote the industry's energy-saving and emission reduction work, the petrochemical association actively implements the energy consumption quota standards for key energy-consuming products. In the first half of the year, it carried out standard publicity and interpretation in such industries as caustic soda, calcium carbide, synthetic ammonia, and yellow phosphorus. “The association held a conference to publicize the national standard for energy consumption quotas for caustic soda-based products, interpreted the implemented standards, and trained the enterprise’s comprehensive energy consumption accountants and their department heads.” Sun Weishan said.
The success of the pioneer companies
"In the industry's energy-saving and emission reduction work, the rank-and-file companies have not scored well." Sun Weishan introduced.
As the largest marine chemical production and export base in the country, in 2007, Shandong Haihua Group realized a current value of 18.326 billion yuan in output value, and consumed 36.071 million tons of fresh water, including 34.27 million tons of fresh water, and 326.45 million tons of reuse water. The recycling rate was 90.5%, which was 0.1% higher than the previous year; the water consumption per million yuan was 18.7 tons, a decrease of 19.01% over the previous year; the water consumption per million yuan industrial added value was 103.75 tons, a decrease of 18.24% over the previous year. Compared with 2006, a total of 8.04 million tons of fresh water were saved in 2007.
Henan Xinlianxin Chemical Fertilizer Co., Ltd. established a water-saving team led by the chief engineer. Organize a number of scientific and technological breakthroughs. In 2007, the company achieved a ton of ammonia consumption of less than 12.5 tons of primary water, and the industrial water reuse rate reached more than 97.8%.
The "old" energy-saving emission reduction advanced enterprise -- Sinopec Zhenhai Refining and Chemical Branch Company achieved the goal of "increasing production, saving water and reducing pollution" under the condition that the amount of crude oil processing increased year after year. In 2007, the amount of crude oil processed by the company was 3.3 times that of 1995, while the sewage discharge per ton of crude oil processed was reduced from 0.74 tons in 1995 to 0.07 tons, and the amount of new water taken per ton of crude oil was reduced from 1.1 tons in 1995. To 0.362 tons, reaching or exceeding the international advanced level in the same industry. Out of the effluent, the concentration of pollutants such as petroleum, COD, and ammonia nitrogen continued to decline in recent years, and the COD emission index per 10,000 yuan was reduced from 1.1 kg per ten thousand yuan in 1995 to 0.01 kg in 2007.
Xinjiang Tianye Group took the lead in the domestic PVC industry to adopt the polymerized mother liquor biochemical treatment recovery technology, which has set a good example for the domestic wastewater treatment industry in the same industry.
The relevant person in charge of Tianye Group stated: “In 2008, based on the reduction in water consumption per unit of product in the previous year, the company further carried out technological transformation and made great efforts to conserve water resources. It is expected that the water saving in 2008 will reach 3 million cubic meters, mainly The volume of water drawn per unit product of PVC products is expected to drop by 15%.”
Energy conservation and emission reduction technology still lacks development
Although the petrochemical industry has achieved certain achievements in energy conservation and emission reduction, Sun Weishan stated that from the current situation, the industry is still faced with considerable pressure for energy conservation and emission reduction:
First, investment in high-energy-consuming products continues to grow faster. Both oil refining and ethylene are high energy-consuming products. If they do not develop, they will rely heavily on imports. However, the energy consumption of oil refining and ethylene accounts for about 20% of the entire industry.
The second is the rapid development of new coal chemical industry. Coal-to-petroleum, coal-to-methanol, and coal-to-dimethyl ether are all competing to develop coal chemical projects, thereby increasing pressure on the industry to save energy and reduce emissions.
Third, the industrial foundation is weak, energy consumption standards and energy consumption statistics systems are not perfect, and the basic situation of energy-saving and emission reduction of the entire industry cannot be counted. Sources of industry organization information also need the support of relevant departments.
Fourth, the development of practical energy-saving and emission-reduction technologies is still lacking, and there is still a considerable gap with developed countries such as Japan. The research, development and promotion of energy-saving and emission-reduction technologies also require further support from national policies. In May, the "National Key Energy Conservation Technology Promotion Directory (First Batch)" was published. The promotion of these technologies requires the follow-up of related preferential policies.
Fifth, the state has introduced support policies for energy conservation and emission reduction. However, there are still difficulties in implementation, and the assessment and certification work has not kept pace.
Sixth, the petrochemical industry still has some backward production capacity (backward equipment and process technology). The exiting countries of these production capacities still lack corresponding mechanisms.
Reporter's Comments: In recent years, various localities have competed for large petrochemical projects, with 10 million tons of large oil refining and 1 million tons of large ethylene. Recently learned from an equipment manufacturing company, the company has begun research and development of 2 million tons of ethylene equipment. While gratifying for the rapid development of China's petrochemical industry, it is deeply felt that the industry's energy-saving emission reduction work is so arduous.
Looking at the rapid development of China's petroleum and chemical industries in recent years, the pace of product structure adjustment has accelerated, but the proportion of high-energy heavy chemical industry is still high.
At present, the proportion of high value-added, low-energy-consuming fine chemical products in developed countries accounts for about 60% of the entire industry. In China, since the "Ninth Five-Year Plan" period, it has been proposed that the fine chemical industry rate should reach 45%. However, to date, this figure is still less than 40%.
It is not difficult to see that the structural adjustment of the petrochemical industry is still under great pressure. At present, it is imperative to accelerate the adjustment of product structure and achieve sustainable development of the industry. At the same time, practical energy-saving emission reduction technologies and equipment should be promoted as soon as possible to establish an effective mechanism for the withdrawal of backward production capacity and guide the friendly development of the industry.
