On October 9, the single unit of the 1.8 million tons per year ethylene glycol production project under Yulin Chemical Company’s demonstration project for the differentiated utilization of coal to produce new chemical materials (hereinafter referred to as the 180 Project) was successfully commissioned in one go. The 180 Project took 3 years to build; on April 28 of this year, the installation was handed over, marking the official start of the commissioning and testing phase. To ensure the successful commissioning of this project from the first attempt, personnel at all levels of the company remained committed to the project site, continuously refining work plans, optimizing workflows, improving coordination mechanisms, and strengthening responsibilities, in order to ensure the timely implementation of the commissioning process. After nearly 6 months of preparation for commissioning, all team members worked together diligently, carrying out tasks ranging from instrument interlock testing, catalyst loading, turbine startup, individual compressor tests, system airtightness checks, joint purging and hot-commissioning, to equipment integrity inspections as well as on-site evaluations by industry experts. Through their concerted efforts, they achieved the remarkable result of a successful commissioning of the facility from the very first attempt. At present, the entire series of ethylene glycol production units are operating smoothly, with all parameters within normal ranges. The entire production process has been established, allowing for the successful production of polyester-grade ethylene glycol products, which further accelerates the company’s development in the fields of new energy and new materials. In the next step, the company will continue to optimize its process technologies in order to enhance the production capacity of the facilities, achieving a double improvement in both output and quality for polyester-grade ethylene glycol, with an annual production volume of 1.8 million tons. It is reported that at the initial stage of planning the demonstration project for the use of coal in various ways to produce new chemical materials, Shaanxi Coal Group engaged several internationally renowned consulting firms such as Roland Berger to conduct research and planning over a period of 5 years. They investigated the market conditions of 116 major chemicals worldwide and reached the conclusion that, taking advantage of Shaanxi’s and northern Shaanxi’s geographical location and resource endowments, and focusing on textile materials, automotive materials, building decoration materials, as well as related industries, it is possible to establish an industrial system with global competitive advantages in northern Shaanxi. The total land area of the project is 23,100 mu, of which the 180 project covers an area of 6,600 mu. The total investment amounts to approximately 26.5 billion yuan. The main product is polyester-grade ethylene glycol with an annual production capacity of 1.8 million tons, while the by-products include industrial-grade (grade 1) DMC at 79,000 tons per year, coal-based ethanol at 12,100 tons per year, heavy-duty diols at 13,600 tons per year, and DMO reconstituent at 38,600 tons per year.
