The world's largest coal chemical project under construction - Yulin Chemical's 1.8 million tons/year ethylene glycol project has opened up the whole process

On October 9, the 1.
8 million tons/year ethylene glycol project (hereinafter referred to as the 180 project) of the 1.
8 million tons/year ethylene glycol project (hereinafter referred to as the 180 project) of Yulin Chemical Company of Shaanxi Coal Group successfully produced polyester grade ethylene glycol products
in a single series.

The 180 project took three years to build, and the device was handed over on April 28 this year, officially entering the stage
of feeding and commissioning.
After nearly 6 months of preparation for start-up, all the personnel of Yulin Chemical from instrument interlock commissioning, catalyst filling, turbine punching, compressor single test, system airtightness, linkage purging and thermal intermodal transportation to equipment integrity inspection and then on-site inspection and evaluation by industry experts, finally realized the one-time successful start-up of the
device.

It is reported that the demonstration project of new chemical materials by coal separation and utilization covers a total area of 23,100 mu
.
Among them, the 180 project covers a total area of 6,600 mu, with a total investment of about 26.
5 billion yuan, the main product is 1.
8 million tons/year polyester-grade ethylene glycol, and the by-products are 79,000 tons/year industrial-grade (first-class) DMC, 12,100 tons/year coal-based ethanol, 13,600 tons/year heavy diol, and 38,600 tons/year DMO recombinant points
.

At present, the whole series of ethylene glycol devices are running smoothly and all kinds of parameters are normal, realizing the whole process and smoothly producing polyester-grade ethylene glycol products, further accelerating the pace of
Yulin Chemical's new energy and new material industry layout.
In the next step, the company will continue to optimize the process technology plan, improve the production capacity of the plant, and achieve a double breakthrough
in the output and quality of polyester-grade ethylene glycol with an annual output of 1.
8 million tons.
