China Drying News In 2011, China's apparent consumption of ethylene glycol reached 10.47 million tons, exceeding the United States as the world's largest consumer of ethylene glycol. In 2011, the output of ethylene glycol in China was only about 3.2 million tons, while the import volume reached 7.27 million tons, and the external dependence was nearly 70%. Under the factors of shortage of oil resources, high oil prices and high cost, and the impact of cheap products in the Middle East, the domestic traditional petroleum route system lacks competitiveness. In the future, only the development of coal-based glycol will reduce the degree of foreign dependence. This is the information obtained from the China Coal Chemical Industry Situation Analysis and Hot Issues Symposium held on November 22-24. Ethylene glycol is mainly used in the production of polyester fibers, antifreeze agents, unsaturated polyester resins, lubricants, plasticizers, non-ionic surfactants, and explosives, paints, and inks. In recent years, with the rapid development of China's polyester industry, the consumption of ethylene glycol in China has continuously increased. The self-sufficiency rate of domestic ethylene glycol has been hovering between 25% and 30% for five years. In 2011, China's ethylene glycol imports amounted to 7.27 million tons, an increase of 9.5% from the 2010 imports. The cheap ethylene glycol in the Middle East has a huge impact on the Chinese market. In 2011, the global ethylene glycol production capacity was approximately 26 million tons, the output was approximately 20 million tons, and the average operating rate was approximately 77%. The global ethylene glycol production capacity was relatively surplus. The Middle East is the main export area, with exports accounting for 93.9% of local production and 51.4% of world exports. At present, domestic production of ethylene glycol mainly uses the oil route, and the product cost is closely linked with the international oil price. The price fluctuates greatly with crude oil. The cost of raw materials accounts for about 50% of the total cost of ethylene glycol. At present, the cost of producing ethylene glycol by petroleum is between 5,500 and 6,000 yuan (t price, the same below). Therefore, when the price of finished ethylene glycol products is below 6,000 yuan, the domestic petroleum products tend to be zero profit. The ethylene glycol products in the Middle East use ethane and propane in the associated gas of oil fields as raw materials, which are inexpensive and even free to use. Therefore, the average price of ethylene glycol landed duty is about 5,120 yuan, and the cost advantage is very obvious. Under the factors of shortage of oil resources, high oil prices, high-priced products in the Middle East, and high water consumption, the domestic traditional petroleum-based ethylene glycol system lacks competitiveness. With corn as raw material, the biochemical process route using ethanol-ethylene-ethylene glycol will not work because of the country's limited food security. Therefore, the coal-to-ethylene glycol route is an inevitable trend. According to Ma Xiaoxun, Dean of the School of Chemical Engineering at Northwest University, China's coal-based glycol technology has a relatively strong competitiveness. The price of ethylene glycol with a coal price of 217 yuan was equal to the cost of importing ethylene glycol in the Middle East. Under the price of crude oil of 80 US dollars/barrel, the ethylene glycol with a coal price of 520 yuan can compete with imported ethylene ethane glycol in the Middle East. The coal price of 580 yuan is equivalent to the level of domestic ethylene glycol. It is understood that the coal-to-ethylene glycol design route is basically based on low-quality low-priced coal such as lignite, and the price of ethylene glycol is much higher than that of methanol. Therefore, the economy of coal-to-ethylene glycol is good. The energy efficiency of coal-based glycol is 25.7%, which is in line with the energy efficiency requirements of the coal chemical demonstration project and is greater than 25%. At present, there are nearly 30 coal-based glycols under construction, proposed construction, and planning projects in China, with a total capacity of more than 8 million tons. However, it is worth noting that the coal-to-ethylene glycol technology is not yet fully mature, there is no industrialized device with long-term stable operation, and no actual production and operation technology and economic indicators have yet been obtained. Coal-based ethylene glycol is still not generally accepted by the polyester industry. It is difficult to make a comprehensive and accurate assessment of the technology economy and competitiveness. It still requires further studies and industrial experiments. It is not appropriate to push forward in large-scale and the key is to do a good job of demonstration. Ma Xiaoxun said that in the cost structure of coal-based glycol, investment and labor costs account for a large proportion, so building a larger-scale production facility on the basis of mature technology can further increase competitiveness. In order to minimize the impact of the import of ethylene glycol in the Middle East on the ethylene glycol industry in China, it is necessary to adjust measures to local conditions and develop cheaper and more readily available raw materials for ethylene glycol production. For example, fertilizer companies in the eastern region can use their existing gas generation capacity to build ethylene glycol units to increase their competitiveness; coking companies can use co-product gas to produce ethylene glycol to further increase the added value of their products; coal companies Coalbed methane can be used. Calcium carbide companies can use calcium carbide furnaces to produce ethylene glycol. While reducing tail gas emissions, they can increase the added value of products. Second and third tier cities can use gas to replace surplus gas and build ethylene glycol plants. Ma Xiaoxun pointed out that locking up resources, appropriately extending the product chain, and improving resource utilization efficiency and energy conversion efficiency are issues worth considering in the development of coal glycol. It is expected that some sets of 200,000-ton/year industrialized production facilities built during the “12th Five-Year Plan†period will be put into production. Through demonstration, debugging, optimization, and improvement, the company will step out of the new road of producing ethylene glycol from coal-based syngas in China.
