According to news from Weihua Group, the 300,000 tons/year coal-to-ethylene glycol project of Shaanxi Weihe Binzhou Chemical Co., Ltd. of Shaanxi Coal and Weihua Group was completed on February 9, 2021. In early March, all three gasifiers were put into operation. On April 8, the 72-hour performance assessment was completed. In June, the coal consumption per ton of ethylene glycol was 2.98 tons, which was far better than the design value of 4.13 tons of coal per ton. The UV transmittance of ethylene glycol products at 220nm can reach 90%. It has successfully entered the major polyester market and has become a quality leader in the coal-based ethylene glycol industry.
As of the end of June, Binzhou had produced a total of 104,500 tons of ethylene glycol, completing 104.5% of the group company’s annual plan.
Weihua Binzhou’s 300,000 tons/year coal-to-ethylene glycol project uses GE’s coal-water slurry gasification technology. Conversion, purification, and gas separation to obtain H2 gas and CO gas, Kochem Co., Ltd.’s ethylene glycol synthesis technology. Overall design by Donghua Engineering Company.
Project Overview
Shaanxi Coal Wei The 300,000 tons/year coal-to-ethylene glycol project of Shaanxi Weihe Binzhou Chemical Co., Ltd. of China Chemical Group is the earliest coal-to-ethylene glycol project established in Shaanxi Province, and it has a leading role in Shaanxi, a major coal-producing province. The project construction site is located in Xinminyuan Modern Coal Chemical Industrial Park, Bin County, and the project covers an area of 600,000 square meters. In April 2016, Shaanxi Weihe Binzhou Chemical Co., Ltd. signed a CTEG technology licensing contract and engineering design contract for the 300,000 tons/year coal-to-ethylene glycol project with Gaochem and Donghua Engineering. The original owner of the project is Shaanxi Binchang Mining Group Co., Ltd. On November 19, 2014, Binchang Mining Group’s 300,000-ton coal-to-ethylene glycol project was officially handed over to Shaanxi Weihe Coal Chemical Group Co., Ltd.
The project construction content includes main projects such as gasification equipment, purification equipment, and ethylene glycol synthesis equipment, as well as public supporting facilities such as water supply and drainage, desalted water stations, power supply, heating, and fire protection. , storage and transportation projects and environmental protection projects such as waste gas treatment, wastewater treatment, and solid waste disposal. After the completion of the project, the annual output of ethylene glycol will be 300,000 tons. By-products: crude DMC 17,576 tons/year, DMO heavy components 5,336 tons/year, fusel oil 5,920 tons/year, the light fraction is 13,440 tons/year, the ethylene glycol heavy fraction is 6,048 tons/year, and the sulfur is 4,321.6 tons/year. The total project investment is 5.495 billion yuan, of which 444 million yuan is environmental protection investment. </p
