Since 20 10, the construction of dimethyl ether in China has become a craze, and many companies plan to introduce technology to build large-scale dimethyl ether production plants through joint ventures and cooperation. In April of 20001year, Shaanxi Xinran gas appliance Co., Ltd. and American Zhaoyun Resources Co., Ltd. signed a project agreement to jointly develop "200,000 tons/year coal-based one-step synthesis of dimethyl ether ultra-clean fuel", with a total investment of 2.03 billion yuan, with the US contributing 90%.
Ningxia 830,000 tons/year coal-based dimethyl ether project plans to invest 4.78 billion yuan, and plans to use foreign capital. Signed a cooperation agreement with Magnet United Company, relying on the technology of American Aerodynamics Company.
Sichuan Luzhou Natural Gas Co., Ltd. has built a two-step dimethyl ether plant with a capacity of 654.38+100000 tons/year, and the second dimethyl ether plant with a capacity of 654.38+100000 tons/year has also started construction.
Shandong Linyi Minglu Chemical Co., Ltd. is building a 30,000-ton/year dimethyl ether plant, adopting the self-developed liquid-phase two-step process technology.
The dimethyl ether project of Shandong Huaxing Group with an annual output of 30,000 tons/year started in August 2004. The factory adopts two-step method.
Shandong Yankuang Group Corporation plans to build a 600,000-ton dimethyl ether plant and introduce foreign one-step dimethyl ether technology.
In addition, many places in China have proposed to build DME plants, such as Southwest Petroleum and Natural Gas Administration, Xinjiang, Shuangyashan in Heilongjiang, Daqing Oilfield, Shaanxi, Lanzhou and Anhui. Dimethyl ether is mainly used as aerosol, aerosol and spraying propellant in China, and it consumes 0.8 million tons of dimethyl ether/kloc-0 every year. Due to the rapid development of aerosol industry in China, it is estimated that about 30,000 tons of dimethyl ether will be needed in 2005 and 40,000 tons in 20 10. In addition, the consumption of dimethyl ether used to synthesize dimethyl sulfate and other chemical products in China is about 1. 1 10,000 tons.
Dimethyl ether can replace natural gas, coal gas and liquefied petroleum gas as civil fuel, because its properties are similar to liquefied petroleum gas and it is easy to store and compress. In 2002, the apparent consumption of liquefied petroleum gas in China was16.2 million tons. At the same time, China began to import a large number of liquefied petroleum gas from 654.38+0990, and the import volume of liquefied petroleum gas in 2002 was 6.26 million tons. If the price of dimethyl ether is appropriate, assuming that dimethyl ether replaces imported liquefied petroleum gas, according to the import volume of 2 1 century, about100000 tons of fuel-grade dimethyl ether is needed. With the continuous improvement of people's living standards, the demand for civil fuels will increase greatly, especially for clean energy such as natural gas, dimethyl ether and liquefied petroleum gas. Therefore, the development prospect of dimethyl ether as civil fuel is very bright.
Dimethyl ether has excellent fuel characteristics, such as convenience, cleanness, high cetane number, good power performance, less pollution and easy storage as liquid under slight pressure. As an alternative fuel for vehicle diesel, it has incomparable comprehensive advantages such as liquefied gasoline, natural gas, methanol and ethanol.
In 2002, China's diesel consumption was 76.62 million tons, and the diesel consumption increased rapidly. It is estimated that the consumption will reach 82.9 million tons in 2005 and 10 1 10,000 tons in 2006. Dimethyl ether, as a good alternative fuel for diesel, needs about 5.53 million tons of dimethyl ether in 2005 and 6.74 million tons in 20 10 according to its replacement rate of 5%.
To sum up, it is estimated that the demand for dimethyl ether in aerosol and chemical industries in China will reach 50,000-60,000 tons in 2005. The consumption of dimethyl ether as alternative fuel mainly depends on the supply of dimethyl ether. If the price of dimethyl ether drops to a level that can compete with diesel or liquefied petroleum gas, it is believed that the consumption of dimethyl ether as fuel will increase rapidly and the market scale will be quite amazing.
As a clean alternative fuel, dimethyl ether has been widely concerned at home and abroad, especially its huge market potential in replacing natural gas, liquefied petroleum gas and diesel oil, which is of great practical significance to the adjustment of energy structure and environmental protection in China.
Dimethyl ether technology is one of the hot spots of technology development at home and abroad. One-step process has the advantages of simple process flow, less equipment, less investment, lower operation cost and production cost. However, due to the complex synthesis reaction and separation process, it has not been fully industrialized in 2 1 century. Two-step process is the main process of dimethyl ether production at home and abroad in 2 1 century, with high product purity, mature process, wide adaptability of the device and strong comprehensive competitiveness, but it also has the disadvantages of long process and large equipment investment.
The popularization and application of 2 1 century dimethyl ether is the key to its development. As a clean alternative energy source, dimethyl ether needs the strong support and help of the government. It is suggested that the state should make overall plans to build large-scale dimethyl ether production bases in areas rich in coal resources but without oil and gas resources. It is expected that dimethyl ether will become an important part of China's energy structure in the near future by taking dimethyl ether as the market leader to replace gas and liquefied petroleum gas, and at the same time vigorously strengthening the research on dimethyl ether replacing diesel oil and comprehensively promoting the production and use of dimethyl ether. Dimethyl ether is a new type of basic chemical raw material, which has many unique uses in medicine, fuel, pesticide and other chemical industries because of its good characteristics of easy compression, easy condensation and easy vaporization. With the shortage of petroleum resources, the rising price and the deepening of the concept of clean environment protection, dimethyl ether, as a clean fuel, has been vigorously promoted as an alternative resource of diesel, and has gradually entered the civil fuel market and automobile fuel market.
On the demand side, the main use of dimethyl ether in China is as propellant of aerosol, aerosol and spraying agent, and it consumes 6.5438+0.8 million tons of dimethyl ether every year. Due to the rapid development of aerosol industry in China, it is estimated that about 40 thousand tons of dimethyl ether will be needed in 20 10.
In terms of diesel oil substitution, China's diesel oil consumption is growing rapidly, and will reach 10 1 10,000 tons in 20 10. Dimethyl ether, as a good alternative fuel for diesel, will need about 6.74 million tons in 20 10 if its replacement rate is 5%.
In view of the signs that the coal chemical industry in some places is heating up too fast and some areas are developing blindly, the National Development and Reform Commission issued the Notice on Strengthening the Construction Management of Coal Chemical Projects to Promote the Healthy Development of the Industry on July 7, 2006, which requires that dimethyl ether projects with a capacity of less than 6,543.8+100,000 tons/year should not be approved in general. This has promoted the construction of large-scale dimethyl ether projects in China, and also promoted the industrialization and scale development of dimethyl ether industry in China.
Under the financial crisis, enterprises with high degree of product marketization and close relationship with oil price and international market are relatively more vulnerable to the impact of the international financial crisis, such as alcohol ether enterprises such as methanol and dimethyl ether. In the 265438+20th century, more than 70% methanol and dimethyl ether enterprises in China stopped production.
The economic crisis is not terrible. The terrible thing is that there is no preparation and countermeasures for the crisis. As Warren Buffett famously said, "Only when the tide recedes can we find out who is swimming naked". Although there are still some problems in China's dimethyl ether industry, the application and market prospect of dimethyl ether are still bright. With the support of national policies, the development momentum is worth looking forward to.
