Shaanxi Coal Chemical Project on

The world’s largest coal chemical project under construction has successfully launched a demonstration project in Yulin, Shaanxi province, northwest China, with quality ethylene glycol products polyester coming off the production lines. The project is expected to reduce the country’s imports of related products and improve the quality of high-end chemicals.

The Coal Chemical Demonstration Project is designed to produce 1.8 million tons of ethylene glycol products per year, according to a statement released Oct. 17 by the Business Council’s Assets Supervision and Administration Commission. of state.

The project was built by a subsidiary of Shaanxi Coal and Chemical Industry Group Co. After three years of construction, it was completed in April and began preparation for production. At present, there is a complete production line for ethylene glycol products, the statement said.

With a total investment of 26.5 billion yuan, the main product of the project is 1.8 million tons of polyester-grade ethylene glycol per year, and its by-products are 79,000 tons of polyester-grade dimethyl carbonate. industrial, and others.

Ethylene glycol is widely used as an antifreeze agent in coolants or as a wetting agent in leather and adhesives.

China has become the world’s largest consumer of ethylene glycol, with imports of related products growing despite rising domestic production, according to media reports.

According to a report published on the Chinese Academy of Sciences (CAS) website, the “carbon to ethylene glycol” technology was independently developed by the Fujian Materials Structure Research Institute under CAS. in 2009.

Replacing ethylene in petroleum with coal to produce ethylene glycol can help boost the production and domestic supply of ethylene glycol, while improving the level of efficient and clean processing and utilization of coal resources, according to the report.

The technology also helps meet the country’s resource conditions, characterized by a shortage of oil and gas and an abundance of coal resources, he added.
