Competition of coal to ethylene glycol 20 10-2-4 In recent years, the rapid development of China's polyester industry has greatly increased the demand for pta and ethylene glycol. The output of ethylene glycol is far from meeting the demand of domestic polyester industry and needs to be imported in large quantities. However, the output of ethylene glycol did not increase much during the same period. In 2008, the domestic ethylene glycol supply and demand gap was 5.2 million tons, and the self-sufficiency rate was less than 30%, so it could only be imported in large quantities to meet the downstream demand. According to the latest data of Yahua Consulting, China's ethylene glycol import in 2009 exceeded 5.8 million tons, an increase of 12% compared with 2008. From 2000 to 2008, the average annual growth rate of ethylene glycol consumption in China was18.4%; In the same period, the average annual growth rate of domestic ethylene glycol supply was 12.3%, and the domestic output growth was far from enough to meet the demand growth. It is precisely because of the supply and demand gap of ethylene glycol in China that the industry pays attention to coal-based ethylene glycol. Yahua Consulting believes that due to the participation of many research institutions and engineering companies, China coal-to-ethylene glycol technology development and engineering will usher in multiple competitive situations. Participants include manufacturing enterprises, engineering companies and scientific research institutions. After nearly 30 years of unremitting efforts, Fujian Institute of Structure of China Academy of Sciences has studied the key technologies of the core catalyst for ethylene glycol production from syngas. In this process, co, no, h2, o2 and methanol are used as raw materials to prepare ethylene glycol through oxidative coupling of oxalate. The coupling and hydrogenation catalysts were developed, which explored a new way for the industrialization of ethylene glycol from coal. 300 tons and 10000 tons of synthetic process tests were carried out successively. From June 5438 to February 2009, Tongliao's 200,000-ton/year coal-to-ethylene glycol industrial demonstration project, the world's first coal-to-ethylene glycol industrial demonstration project using the technology of Institute of Material Structure of Chinese Academy of Sciences, completed the whole process, completed a one-week trial operation and produced qualified products. It is expected that the 20 10 project will be further debugged to realize commercial operation. In September, 2009, Hubei Institute of Chemistry completed the research on three key catalysts in the "New Process for Synthesis of Polymeric Grade Ethylene Glycol from Coal Gas". And passed the appraisal of the results of the small test. Three key catalysts include selective dehydrogenation, synthesis of dimethyl oxalate and hydrogenation of dimethyl oxalate. 20 10,10 In June, the groundbreaking ceremony for the pilot project of producing ethylene glycol from coal-based syngas, jointly organized by China Wuhuan Engineering Co., Ltd., Hubei Institute of Chemistry and Hebi BMW Group, was held in the BMW Group in Shancheng District of Hebi City. Relying on the existing methanol plant and engineering facilities of BMW Group, a pilot plant with an annual output of 300 tons of ethylene glycol and an industrial plant with an annual output of 200,000 tons will be built. In addition, Huayi Group Shanghai Coking Company, together with relevant universities and research institutions, has developed the core technology of coal-to-ethylene glycol, and is ready to build a 10,000-ton pilot plant. Universities and other engineering companies, such as Tianjin University, are also developing technologies for producing ethylene glycol from coal. Coal-to-ethylene glycol has created a new source of raw materials for ethylene glycol production, and its industrialization demonstration has been included in the petrochemical revitalization plan in 2009. Due to the mature ethylene glycol market and high price, coal-based ethylene glycol has a good profit prospect, which will become a new bright spot in China coal chemical industry in 20 10. The first technical and economic seminar on coal-to-ethylene glycol will be held in the second quarter of 20 10. Yahua Consulting's research report shows that by 20 12, China's total ethylene glycol production capacity will be 4.6 million tons/year, and the output should be about 3.45 million tons based on the operating rate of 75%. On the demand side, it is estimated that by 20 12, China's ethylene glycol consumption will exceed10.5 million tons. The gap between supply and demand will reach 7.05 million tons. Coal-to-ethylene glycol has a huge market space in China. Yahua Consulting believes that the competitors of China's coal-to-ethylene glycol include not only domestic integrated petrochemical enterprises, but also enterprises in the Middle East that produce ethylene glycol with low-priced ethane or naphtha. In the next few years, the market demand for ethylene glycol in China will increase steadily. The production cost, the reliability of process technology and the stable operation of the device will be the key to determine its competitiveness.
