Shaanxi Coal Yulin Chemical Coal Fractionation and Utilization Project started and successfully put into feeding

"I announce that Yulin Chemical's 15 million tons/year coal fractionation utilization project has started the project and started the project successfully!" "Yulin Chemical's 500,000 tons/year DMC project site started!" On January 4, with the instruction of Shang Jianxuan, member of the Party Committee and deputy general manager of Shaanxi Coal Group, the 15 million tons/year coal fractionation utilization project of Shaanxi Coal Yulin Chemical located in Yulin Yushen Industrial Zone, Shaanxi Province successfully started the project feeding and the groundbreaking ceremony of the 500,000 tons/year DMC project site
.

Yang Xiangxi, member of the Standing Committee of the Yulin Municipal Party Committee and vice mayor, said that the 15 million tons/year coal fractional utilization project, as the largest coal chemical project under construction in the world, has realized the extension and expansion of the coal chemical industry from bulk basic chemicals to coal-based special fuels, coal-based biodegradable materials and other fields through whole-process, whole-link and full-chain green innovation, which has effectively promoted the transformation and upgrading of Yulin's high-end
energy and chemical base 。 It is hoped that Yulin Chemical Company will base itself on a new starting point, closely focus on the development requirements of "three modernizations", increase independent innovation in science and technology, continue to extend the chain to supplement the chain and strengthen the chain, build a green industrial chain of coal deep processing and a coal-based high-end material industry cluster with obvious scale advantages in Yulin as soon as possible, and explore a green
, low-carbon, clean and efficient coal chemical industry with Yulin characteristics and Shaanxi coal characteristics of high-end, diversified and low-carbon development.

Song Shijie, assistant general manager of Shaanxi Coal Group and chairman of Yulin Chemical Company, said that Yulin Chemical Company shoulders the mission of transforming and upgrading Shaanxi coal industry and promoting the industrial agglomeration of high-end energy and chemical bases in northern Shaanxi, and the 15 million tons/year coal fractional utilization project undertakes represents the development direction of coal chemical industry, with the characteristics of high comprehensive utilization efficiency of coal as a chemical raw material, high-end, diversified and low-carbon products, etc.
, which is a beneficial exploration and attempt of clean and efficient conversion path of coal.
It is also a specific measure to actively promote the integration of high-end energy and chemical parks, refinement, materialization and upstream and downstream in northern Shaanxi, and strive to build a complete industrial chain of coal deep processing, which is of great
significance to promoting the implementation of the "dual carbon" goal and ensuring national energy security.

It is understood that the 15 million tons/year coal fractional utilization to make chemical new materials demonstration project has been listed in the national "13th Five-Year Plan" for energy development, "Coal deep processing industry demonstration "13th Five-Year Plan" and so on
.
The total investment of the project exceeds 200 billion yuan, and it is constructed in two phases, including the first phase of the construction of 1.
8 million tons/year ethylene glycol project and the pyrolysis start-up project of 15 million tons/year coal separation clean and efficient conversion demonstration project; The second phase is to build a 15 million tons/year coal separation clean and efficient conversion demonstration project olefin, aromatics and deep processing engineering
.
Through the efficient conversion of coal, the production of bulk platform products such as ethylene glycol, methanol/olefin, aromatics, and base oils, and further deep processing to produce four categories of terminal products such as high value-added materials, battery electrolytes, degradable plastics and special oils, the project will open up an innovative path of low-cost and high-efficiency coordinated development of coal chemical industry and petrochemical industry that is both "dislocated" and "integrated", and provides a new strategic plan
for ensuring national energy security.

The 15 million tons/year coal fractional utilization project has created a number of firsts
.
On October 9, 2022, the world's largest 1.
8 million tons/year ethylene glycol plant successfully produced qualified polyester-grade ethylene glycol products in a single series of one-time start-up, and on November 25, the whole series of processes was opened, and the whole system is currently running
at full capacity 。 After the project is put into operation, it will account for 17% of the total domestic coal-based ethylene glycol production capacity, replacing nearly 1/4 of the total imports; the 1.
2 million tons/year pulverized coal pyrolysis project in the project is China's first single-series million-ton pulverized coal pyrolysis industrial demonstration unit, using independent innovative technology through oil pulling, gas extraction and other coal quality utilization methods, increasing the proportion of H and C elements in coal into the back-end products, improving comprehensive energy efficiency, reducing carbon emissions, and amplifying the demonstration effect of advanced technology of "Shaanxi coal version" coal fractionation.
Amplification effect of oil and gas substitution, strategic effect
of technology migration.
On December 26, 2022, the pulverized coal pyrolysis project was put into operation and produced pulverized coke and coal tar
.
At present, the process flow has been fully opened, and the device runs smoothly
.

Dimethyl carbonate (DMC) is a natural and versatile organic chemical product with excellent environmental performance, and high-purity dimethyl carbonate can be used in lithium battery
electrolytes.
The 500,000 tons/year DMC project is an important part of Yulin Chemical's upstream and downstream integrated coal comprehensive utilization industrial cluster using the mode of "nesting and attracting phoenixes, attracting business and investment", and it is also the largest battery electrolyte solvent project
in China.
The total investment of the project is about 4.
7 billion yuan, which is divided into two phases, the first phase of which is a 100,000 tons/year DMC project
.

During the meeting, the participants observed the central control room of Yulin Chemical and the 500,000 tons/year DMC project site, and witnessed the company's 1.
8 million tons/year ethylene glycol project operation, the successful commissioning of the 15 million tons/year coal separation utilization project and the start of the 500,000 tons/year DMC project in the form of video connection
