Recently, an investor asked Xinjiang Tianye: What is the current production capacity of ethylene glycol? How much new production capacity will be added in 2021? The company responded that the 600,000-ton-annual syngas-to-ethylene glycol project undertaken by Xinjiang Tianye Huihe New Materials Co., Ltd. is currently in the trial production stage.
As of December 30 last year, all polyester-grade ethylene glycol products produced by Xinjiang Tianye Huihe New Materials Co., Ltd. were sold to Jiangsu and Zhejiang, and the supply of products exceeded demand. Tianye Huihe New Materials Co., Ltd. is responsible for the construction and operation of Tianye Group’s annual output of 600,000 tons of ethylene glycol project. This key project of the Corps, with an investment of 7.997 billion yuan, is currently the largest coal-to-ethylene glycol project in a single unit in China, and is also the project with the longest industrial chain extension in the city. After reaching production capacity, the company can achieve an output value of approximately 3.3 billion yuan.
According to researcher Li Xuekuan, chief engineer of the Applied Catalysis and Green Chemical Research Office of Shanxi Institute of Coal Chemistry, Chinese Academy of Sciences, who has been committed to coal chemical research: “In the past ten years, the domestic market has The demand for glycol is growing rapidly. Ethylene glycol is mainly used in the production of polyester, polyester, paint solvents, cold-resistant lubricants, etc. In the domestic coal-to-ethylene glycol production process, the technical level of the ethylene glycol unit in Shihutan Park is The highest, the production cost is the lowest.”
Currently, countries such as Saudi Arabia and the United States use petroleum production methods to produce ethylene glycol. The coal-to-ethylene glycol production method can effectively alleviate the current situation of “poor oil and rich coal” in my country. At the same time, it can effectively improve the level of efficient and clean conversion and utilization of coal resources, which has had an important impact on the national energy and chemical industry.
It is understood that in addition to mastering the most advanced technology of the current domestic coal-to-ethylene glycol production method, Tianye’s coal-to-ethylene glycol project with an annual output of 600,000 tons has been in operation since 2017. Since construction started in August, many breakthroughs have been made.
The project construction speed is the fastest in the industry, more than half a year ahead of similar domestic enterprises;
With Tsinghua University, A number of core technologies jointly developed by scientific research institutes such as the Dalian Institute of Chemical Physics of the Chinese Academy of Sciences have broken through many industry problems and can provide valuable experience for the construction of large-scale ethylene glycol production lines in China;
The ethylene glycol produced has good UV transmittance and a purity of 99.96%. All indicators are higher than the national standards and can meet the highest requirements for ethylene glycol indicators in China’s polyester industry;
The product has significantly reduced the production cost of domestic coal-based ethylene glycol, driven domestic ethylene glycol products to compete with foreign products, and also improved the ability of relevant Chinese enterprises to withstand market risks;
Coal-to-ethylene glycol production technology can equally replace petroleum production technology.
The biggest advantage of this project is that it couples the coal chemical industry with Tianye Group’s existing chlor-alkali chemical industry. In the later stage, Tianye Group will also integrate coal-to-ethylene glycol technology with the petrochemical industry to promote industrial intensification and agglomeration, and promote the continuous extension of the circular industry chain. After the ethylene glycol project with an annual output of 600,000 tons is fully completed, it will provide new momentum for Tianye Group’s economic growth. At the same time, it can also support the follow-up projects of Shihutan New Materials Industrial Park – the construction of polyester and special fiber bases, high-end olefins and Providing raw materials for the construction of engineering plastics bases. The Corps plans to build the Shihutan New Materials Industrial Park into the Corps’ first industrial park with an output value of 100 billion yuan.
Project Overview
Xinjiang Tianye Group’s annual output of 600,000 tons of ethylene glycol project is ten The first project of Hutan New Materials Industrial Park, with a total investment of 7.997 billion yuan, started construction in August 2017. Relying on Xinjiang’s abundant coal resources and advanced coal chemical technology, Tianye Group uses coal-water slurry gasification, syngas purification, purification, separation technology and dimethyl oxalate synthesis and hydrogenation technology to produce polyester-grade ethylene glycol. The project’s equipment scale and process level are in the leading position in the industry. It has been comprehensively optimized in terms of safety, environmental protection, intelligent control, etc., and its production capacity and single production line scale are among the leading positions in the country. </p
