Recently, Gao Dongsheng, deputy director of the Department of Energy Conservation and Comprehensive Utilization of the Ministry of Industry and Information Technology, stated: “In the 12th Five-Year Plan period, the national energy-saving and emission-reduction targets will be decomposed to enterprises.†The number of enterprises in the industry and enterprises and the state’s key monitoring and assessment may be adjusted from 1,000 to 3,000 or even 5,000 during the “Eleventh Five-Year Plan†period. It can be seen that the work of energy saving and emission reduction is the key point during the 12th Five-Year Plan period. The state has increased the pace of energy-saving and emission-reduction work. From the face-to-point arrangement, it is believed that there will be striking results during the 12th Five-Year Plan period.
As we all know, the task of energy conservation and emission reduction in the petrochemical industry is arduous and difficult. On the one hand, China's petroleum and chemical industry still focuses on the production of basic raw material products. The proportion of fine chemical industry is small, energy consumption is high, and pollutants are discharged. It is difficult to completely change the larger features. On the other hand, the average annual growth rate of China's petroleum and chemical industries in recent years is above 20%. This is equivalent to recreating a petrochemical industry of the same size in a few years. With such an industrial structure, at such a pace of development, it is very difficult to achieve the goal of a 20% reduction in energy consumption and a 10% reduction in emissions.
At the same time, experts also pointed out that the difficulty of energy-saving and emission reduction work in the petroleum and chemical industries has three aspects:
First, high energy consumption and high pollution product production capacity grows too fast, and it is difficult to curb growth. In recent years, investment growth in nitrogen fertilizers, soda ash, caustic soda, calcium carbide, and yellow phosphorus has increased at a rate of about 30%. The problem of overcapacity is serious. . At the same time, weak regulatory mechanisms and local protection have prevented national industrial policies from being implemented, and it is very difficult to reverse the trend of high energy consumption and high-pollution products.
Second, the basic work of energy-saving and emission-reduction in the industry The statistical methods for the weak energy consumption and pollutant emissions are not perfect. Some of them were formulated more than a decade ago and they are no longer suitable for the needs of the current industry; some have no standards at all and need to be studied immediately. . Even the statistical data of the National Bureau of Statistics, there are many needs of various industry associations to help verify. In addition, the statistics and management team for energy conservation and emission reduction are weak, and many companies do not have full-time energy and environmental management personnel.
Third, the development and promotion of energy-saving and emission-reduction technologies are insufficient. The promotion of energy-saving and emission-reduction work requires technical support. In recent years, companies have invested more in expanding their scale, but insufficient investment in technology development for energy conservation and emission reduction. Even though some companies have developed good energy-saving and emission-reduction technologies, some are not willing to share in the industry because of their own interests. In addition, for those industries that already have mature energy-saving and emission-reduction technologies, the state has also shown insufficient efforts in promoting technology and setting up special support.
Scientific and technological innovations in chemical companies have significant energy-saving and emission-reduction effects. Sub-sectors in the petrochemical industry should promote energy-saving and emission-reduction technology innovation according to their own conditions. For example, traditional high-energy-consuming industries such as caustic soda, soda ash, fertilizer, calcium carbide, etc., should develop and develop a number of new energy-saving equipment to significantly reduce energy consumption; dyes, pesticides, intermediates, organic materials and other high material consumption and high pollution industries should pass Develop a batch of cleaner production processes and technologies to substantially reduce pollutant emissions. Although it is difficult to save energy and reduce emissions, chemical companies have made significant achievements in energy conservation and emission reduction through technological innovation.
Yuntianhua is a giant enterprise producing fertilizers and has unique insights on waste disposal. Therefore, Yuntianhua Group has achieved remarkable results in energy conservation and emission reduction. In the series of energy-saving and consumption-reduction measures introduced by Yuntianhua, the Group's Chongqing International Composite Materials Co., Ltd. invested 30 million yuan to implement the oxygen-firing technology of glass fiber tank kiln, which is most noticeable.
The project introduces the world's advanced oxygen-free combustion technology to allow oxygen to support natural gas, which can make natural gas more fully burned, and the temperature is higher than the air combustion temperature, thereby increasing the melting capacity and the quality of the glass liquid, and avoiding the production of nitrogen oxides at the source. , Reduce the consumption of natural gas and emissions, with energy saving, environmental protection and other advantages. According to calculations, pure oxygen combustion can save 30% to 40% of fuel compared to air combustion, and reduce emissions by 70% to 80%.
Liao Lihua, Director of the Energy Conservation Office of Yuntianhua Group, introduced that the group has invested 1.176 billion yuan to speed up the elimination of backward production capacity, implemented more than 270 technological transformation projects for energy saving and emission reduction, and focused on the use of sulfuric acid low temperature heat energy utilization projects, thermal phosphoric acid waste heat utilization projects, and international Chemical energy-saving technological transformation project of chemical red phosphorus branch, comprehensive utilization project of yellow phosphorus tail gas of Malong industry and other major energy-saving projects. By July 2010, Yuntianhua Group had realized 1.952 million tons of standard coal, which had a comparable output value, and had exceeded the 688,738 tons of standard coal energy-saving responsibility target signed by Yuntianhua Group and the provincial government during the “Eleventh Five-Year Plan†period. At present, in order to support Kunming City to complete this year's energy-saving goals, the Group took the initiative to take measures to reduce energy consumption by 150,000 tons of standard coal.
Lutianhua has significant energy-saving and emission-reducing effects, and it requires that all units' energy-saving and emission-reduction work should always be centered on the long-cycle center. The general adjustment room is responsible for the scientific scheduling of energy, optimizing the configuration, and ensuring the optimal operation of each unit. The production supervisor of the production department is responsible for the optimization of the key parameters of the production process, guides the workshop to organize the safety, stability, and long-term operation of the equipment, and reduces the energy consumption of various products; the equipment manager is responsible for the periodic determination of the equipment status, scientifically organizing maintenance, and ensuring that the equipment is in good condition and Operational efficiency. The maintenance workshop meticulously maintains monitoring equipment to prevent the equipment from running, running, dripping or leaking. The production and operation workshop strictly controls the operation and control according to the operation regulations, reasonably adjusts the process parameters, eliminates the abnormal working conditions in time, and ensures that the process system is normal and stable. The environmental protection department actively controls and monitors all emission points of the company to prevent excessive emissions.
