As an important alternative energy source, the construction of coal-to-metal dimethyl ether projects is in full swing everywhere. According to the hot issues in the coal chemical industry and the coal-based dimethyl ether industry that are currently the most concerned in the industry, the reporter recently specially interviewed China National Petroleum and Chemical Industry. Li Yongwu, president of the Industrial Association, asked him to interpret the relevant issues.
Reporter: Since the beginning of this year, international oil prices have repeatedly exceeded the 100-dollar mark. Some experts predict that high oil prices mean the arrival of the post-oil era. This gives coal chemical industry a very good opportunity for development. What are the advantages of developing the coal chemical industry?
Li Yongwu: With the rapid development of China's economy, the demand for oil and natural gas and other energy sources is increasing. The problem of energy shortage is obvious. Among them, despite the implementation of a number of measures, it is difficult to solve the fundamental problem of crude oil shortage. Every year, nearly half of the crude oil needs to be imported, while the international oil price has repeatedly hit a new high, and even recently exceeded US$102 per barrel, which is far greater than the increase in coal prices. . Under this background, the substitution effect of coal on crude oil is increasingly evident. China's coal resources are relatively abundant. At the same time, some coal chemical technologies have also achieved breakthrough development and reached the international advanced level. The sustainable development of the national economic strategy makes coal chemical industry inevitably occupy an increasingly important position in the future energy development. Therefore, the solution to the shortage of crude oil will depend to a large extent on the production of coal-to-methanol, dimethyl ether, coal-to-olefins and coal-finished products from the coal chemical industry.
Reporter: Someone put forward the concept of “green coal chemical industryâ€. Please read it. What are the meanings of green coal chemical industry?
Li Yongwu: To develop the coal chemical industry, we must adhere to high standards and high standards. We must use today’s advanced coal chemical technology and strive to develop “green coal chemical industryâ€. To develop "green coal chemical industry," first, we must adhere to scientific and technological innovation, eliminate backward technologies, limit the application of high water consumption processes and equipment, vigorously promote new technologies and technologies that are conducive to energy conservation and emission reduction, and second, we must develop circular economy and do Long industry chain, to achieve the comprehensive utilization of waste water, waste gas, waste residue resources; The third is to achieve the organic integration of industrial development and environmental protection, the coal chemical industry and the environment to develop harmoniously, and take the road of sustainable development.
Reporter: The development of coal chemical industry is most typical of the relevant industrial chain represented by coal-to-methanol, and the release of dimethyl ether as a national standard for civilian fuels has made coal a raw material for the production of clean fuel such as dimethyl ether. At present, the development status of China's dimethyl ether industry, what advanced technologies are worth promoting, and what are the investment opportunities?
Li Yongwu: The future development direction of coal chemical industry mainly includes alcohol ether fuels, coal-to-olefins (MTO, MTP) and coal oil, and methanol-made dimethyl ether is currently the most popular alternative fuel program in China. As a new type of clean energy, dimethyl ether is listed as a project of saving and replacing petroleum by the state, and the product standard of the dimethyl ether alternative fuel industry of the People's Republic of China has also been promulgated and implemented. Dimethyl ether can not only be used as automotive fuel, but also as a substitute for liquefied petroleum gas for civilian fuels. In recent years, the dimethyl ether industry in our country has developed rapidly. The development of the dimethyl ether industry has been gradually initiated throughout the country. Large-scale dimethyl ether projects are under construction in Zhangjiagang, Jiangsu, Inner Mongolia, Shanxi and Tianjin. Currently, dimethyl ether production capacity has been Breaking through 1 million tons, the total production capacity of dimethyl ether in planning and construction reached more than 10 million tons. In the field of coal-to-dimethyl ether, a new "liquid phase process for the dehydration of complex acid in the production of dimethyl ether" has attracted industry attention. This technology developed by the Jiutai Energy Group not only reduces investment, but also eliminates media. Corrosion and contamination, simple post-treatment processes, and high product purity. Moreover, since the methanol used in the production of dimethyl ether has been applied to the technology of “turbine-driven reciprocating compressorsâ€, the electricity consumption per ton of methanol produced is only over 400 kilowatt-hours, which is higher than the power consumption of more than 1,000 kilowatt hours normally required. The energy saving has been greatly improved. In the long run, due to the impact of energy shortages and the active guidance of national policies, the development of DME industry is in full swing and investment prospects are promising.
