Ethylene glycol capacity and output analysis and future development trend

ethylene glycol capacity and output analysis and future development trend

March 22, 2005

in 2004, China had a total of 10 sets of ethylene glycol production units, with a total annual production capacity of 1.116 million tons; The output of ethylene glycol was 949100 tons, about 2.1% lower than that in 2003

ethylene glycol manufacturers in China are mainly distributed in Sinopec and PetroChina. Among them, Sinopec has 6 subsidiaries with an annual production capacity of 78, which has played an important role in stabilizing China's industrial growth and accelerating the transformation and upgrading of the manufacturing industry. 7000 tons, accounting for about 70.5% of the country's total production capacity; PetroChina has four subsidiaries, with an annual production capacity of 329000 tons, accounting for about 29.5% of the total national production capacity. Although China's ethylene glycol production capacity and output have increased rapidly in recent years, due to the strong demand of polyester and other industries, it still cannot meet the growing demand of the domestic market, and a large number of imports are still needed every year, and the import volume is increasing year by year. According to customs statistics, the import volume of ethylene glycol in China reached 2516100 tons in 2003, an increase of 17.3% over 2002, accounting for about 65.8% of the total domestic consumption; In 2004, the import volume increased to 3.391 million tons, an increase of 34.8% over 2003, accounting for 78.6% of the total domestic consumption

in view of the fact that the domestic ethylene glycol production capacity and output cannot meet the actual consumption needs, many enterprises are still preparing to build or expand production units. Among them, Yanhua company plans to expand its current annual production capacity to 300000 tons, and it is expected to complete the expansion plan this year; Shanghai Petrochemical Company plans to build a new 380000 ton production unit, which is expected to be put into operation by the end of this year, when the company's annual ethylene glycol production capacity will reach 600000 tons; Nanjing Yangba company plans to build a new 300000 ton unit, which is expected to be put into operation this year; CNOOC Shell Petrochemical Co., Ltd. plans to build a 320000 ton unit in the South China Sea, which is expected to be put into operation this year; Jiangsu Taicang plans to build a 60000 ton plant; Ningbo United States Xiehe Petrochemical Group Co., Ltd. plans to build a 120000 ton production plant; A 100000 ton plant is proposed in Xinjiang; Dow Chemical Tianjin ethylene project plans to build a 300000 ton plant; Liaoyang Petrochemical Fiber Company plans to expand its current annual production capacity to 200000 tons

it is estimated that by 200, the growth of China's plastic machinery industry has ushered in a golden period of rapid growth. In seven years, China's annual ethylene glycol production capacity will reach 2.4 million tons, which can alleviate the tense contradiction between supply and demand in the country to a certain extent

at present, ethylene glycol in China is mainly used to produce polyester, antifreeze, etc. Its consumption structure: About 83.8% is used to produce polyester, and 16.2% is used to produce antifreeze and other products. It is estimated that by 2007, the total consumption of ethylene glycol in China will reach 4.6 million tons. Therefore, although the annual production capacity of ethylene glycol in China is expected to reach 2.4 million tons in 2007, even if the unit is operated at full power, there will still be a gap of 2.2 million tons that needs to be solved by import

however, on the whole, the world's ethylene glycol production capacity has been in surplus, while the consumption in Asia, especially China, is increasing, which is bound to have more foreign products flowing into China, posing a certain threat to the future development of China's ethylene glycol industry. At present, the total capacity of domestic ethylene glycol is insufficient, the output is small, the scale of the device is small, the technology is relatively backward, the fracture of the sample is always on both sides, the production cost is high, the economic benefit is poor, and it is lack of competitiveness in the international market. Therefore, China should actively adopt advanced technology, expand the scale of the device, reduce production costs, and improve output and quality. In addition to considering importing ethylene glycol and tapping the potential of existing units, it is suggested to introduce foreign advanced technology and build several new large units with a scale of more than 300000 tons as soon as possible

at the same time, due to the current single downstream consumption field of ethylene glycol in China, if polyester production is blocked, it will inevitably cause a fatal blow to the domestic ethylene glycol industry. Therefore, China should also strengthen the application and development of ethylene glycol in other fields. Lee Kuan Yew believes that the situation of single use should be gradually changed
