The world's first coal-based oxalic acid and ethylene glycol plant to produce qualified products

At present, the global ethylene glycol production capacity has been over-supplied, but the production in Asia cannot meet the demand. It has to import large quantities every year. The ethylene glycol in the Chinese market is in short supply. In this context, domestic ethylene glycol construction is in full swing.
With the 650,000 tonne ethylene oxide/ethylene glycol plant of Sinopec Zhenhai Refinery and Chemicals Co., Ltd. located in Ningbo, Zhejiang Province, it was put into operation in late April and produced qualified products. Sinopec’s total ethylene glycol production capacity in East China reached 2 million tons. Companies include Shanghai Petrochemical, Zhenhai Refining, Yangzi Petrochemical and the joint venture Yangzi-BASF. Zhenhai Refining and Shanghai Petrochemical have become the two largest ethylene glycol manufacturers in China. Among them, Zhenhai Refinery's new ethylene glycol plant is part of the Zhenhai Group's 1 million tonne/year ethylene unit that has just been put into production. It adopts a traditional petrochemical route, ie ethylene oxidation to ethylene oxide, and then hydration of ethylene oxide. Ethylene glycol is produced.
On April 25th, the 158,000 tons/year ethylene glycol project of China North Industries Chemical Industry Group Liaoning North Chemical Industry Co., Ltd. entered the trial production stage. This device is the first device in China to use a highly selective, high conversion rate catalyst. The production line is imported from the US SD company. The technology maturity is high. It can ensure the safe, stable and continuous operation of the device while reducing the parking during the reaction. Times, to minimize the production of by-products, to ensure the stability of product quality.
In addition to traditional petrochemical routes, the coal-to-ethylene glycol route is also emerging in China. Coal-based glycol is mainly oxidatively coupled to carbon monoxide to produce dimethyl oxalate, and then dimethyl oxalate is catalytically hydrogenated to ethylene glycol. As one of the five major demonstrations of modern coal chemical industry, coal-based ethylene glycol was included in the national petrochemical revitalization plan in 2009. As of the first quarter of 2010, there are nearly 20 coal-to-ethylene glycol projects planned in China with a total investment of nearly 50 billion yuan. Tongliao Gold's 150,000 tons of coal-to-ethylene glycol capacity is expected to be realized this year.
As the world’s largest consumer of ethylene glycol, China’s consumption will account for about one-third of the world’s consumption in 2010. From 2008 to 2010, China will add 2.20 million tons of ethylene glycol per year, of which approval has been passed 161 million tons/year. It is expected that China's total production capacity will reach about 4 million tons this year, and the total demand for ethylene glycol will reach about 7.1 million tons. Due to the supply gap in the domestic ethylene glycol market, coal-to-ethylene glycol is a promising direction for the development of coal chemical industry, and the threshold for coal-based glycol technology is relatively high. At least in the short term, no projects can be launched leading to excess domestic production capacity. risk. However, some analysts pointed out that the total global ethylene glycol consumption this year is expected to reach 21.88 million tons, and the total production capacity of 27.09 million tons, due to excess global production capacity, the Chinese market is facing the impact of low-cost products in the Middle East.
In the next few years, China will become a competitive market for global ethylene glycol manufacturers. With the commencement of production of large-scale ethylene glycol projects in Asia, the contradiction in the long-term supply of ethylene glycol products in this region will be alleviated to some extent, but there is still a large gap between supply and demand. Faced with the rapidly expanding market in Asia, especially China, major companies in the world have stepped up the construction and expansion of ethylene glycol production capacity. In addition to countries such as Canada, the United States, South Korea, and Japan, which have traditionally exported ethylene glycol to China, Saudi Arabia and Other Middle Eastern countries have produced ethylene glycol based on their cheap ethane raw materials, and their market share in China is rapidly increasing.
The data shows that in 2009, China's ethylene glycol imports exceeded 5.8 million tons, an increase of 12% over 2008. From 2000 to 2008, the average annual growth rate of ethylene glycol consumption in China was 18.4%. The average annual growth rate of domestic ethylene glycol supply during the same period was 12.3%. Domestic output growth was far from enough to meet the demand growth.
Based on good market prospects, coal-to-ethylene glycol is drawing close attention from the domestic coal chemical industry. In fact, after being included as a key demonstration project supported by the state last year, the coal-based glycol has become a hot spot in the market after it was included in the petrochemical revitalization program. Due to the maturity of ethylene glycol market and higher prices, coal-to-ethylene glycol has a good earnings outlook and will become a new bright spot for China's coal chemical industry in 2010.
