Recently, the central control building project of Yulin Chemical Phase II Phase I of Shaanxi Coal Group, which is under the general contracting of China Chemical Engineering Donghua Company, has successfully topped out its main structure 7 days ahead of schedule, providing strong support for the intelligent construction and subsequent commissioning and operation work of the project.

The core role of the central control building

The Central Control Building project is currently the largest single control room building undertaken by the company under the EPC general contracting mode, with a total construction area of approximately 12000 square meters. As the core platform for production and operation monitoring, scheduling and command, data processing, and safety assurance of the Phase II Phase I project, it is like the central brain of production and operation, with a leading construction scale and functional standards in the industry.

As of now, the project has completed a total of 49 concealed works inspections, and the first acceptance pass rate has reached 100%, laying a solid quality and safety defense line for the early topping out of the main structure. Next, the project department will focus on promoting the construction of secondary structures, installation of steel roof trusses, and installation of electrical and instrumentation equipment to ensure that the overall construction task of the central control building is completed with high quality as planned.

Overall Overview of the Project

The Shaanxi Coal Group Yulin Chemical 15 million tons/year coal quality clean and efficient conversion demonstration project fully relies on the abundant coal resources in Yulin area, with coal quality utilization technology as the core, and through the two core paths of coal to olefin and coal to aromatic hydrocarbon, realizes the deep integration of various platform compounds in modern coal chemical and petrochemical industries, extends the industrial chain, and ultimately produces 45 types of products in four categories: high value-added materials, degradable materials, battery electrolyte solvents, and special oil products.

The Yulin Chemical Phase II Project is currently the largest single investment coal chemical project, with a total investment of 176 billion yuan in chemical equipment. On the basis of the first phase of the project, this project focuses on coal pyrolysis, coal tar hydrogenation, and powder coke gasification technologies. Through the systematic integration of coal pyrolysis, coal/semi coke gasification, and downstream deep processing technologies, it further expands and extends the industrial chain, explores new paths for the coupling development of coal based olefins and coal based aromatics, and ultimately produces various chemical products such as polyolefins, polyesters, and polycarbonates. It is expected that the annual sales revenue will reach more than 90 billion yuan. Among them, the total area of the Phase II Phase I project is about 9200 acres, and the estimated total investment of the project is about 62 billion yuan. After the project is completed and put into use, it is expected to have an average annual sales revenue of 20.7 billion yuan and a post tax profit of 3.3 billion yuan. The gasification process will use 9 3500 ton aerospace furnaces.Editor/Gong Ziwei
