On June 10, the second circulating water system for this facility, constructed by Shaanxi Chemical Construction, was delivered successfully, marking the entry of this system into the production preparation phase. This system will provide circulating cooling water for gasification units, purification units, separation units, power stations, demineralization stations, as well as for liquid loading operations via rail. The 1.8 million tons per year ethylene glycol production project at Yulin Chemical, belonging to Shaanxi Coal Group, is currently the largest coal-based ethylene glycol facility under construction in the world. Shaanxi Huajian is primarily responsible for the construction of tasks such as the hydrogen supply and solvent as well as light oil combined hydrogenation units, the second circulating water system, the desalinated water station, the regional cabinet rooms, the heat exchange stations, the fire pump stations, and the 35KV regional substation for this project. The 15 million tons per year demonstration project for the clean and efficient conversion of coal into various products, operated by Shaanxi Coal Group Yulin Chemical Co., Ltd., is located within the Qingshui Coal Chemistry Industrial Park in the Yulin-Yushen Industrial Park. The investment in this project amounts to 26.2 billion yuan, and it will be constructed in two phases and four stages. Phase 1 of the project is divided into two stages: Stage 1 involves the construction of an ethylene glycol plant with an annual production capacity of 1.8 million tons. The site area for this phase is approximately 4.4 million square meters, and the total investment required is around 26.5 billion yuan. It is currently the largest coal-based ethylene glycol production facility under construction in the world. In the second phase, projects for the production of 5.6 million tons per year of methanol, 2 million tons per year of olefins, and related deep-processing facilities will be constructed. Phase II of the project focuses on coal pyrolysis and is also divided into two stages. The first stage involves an industrial demonstration facility for the pyrolysis of 1.2 million tons per year of pulverized coal and the deep processing of 500,000 tons per year of coal tar. In the second stage, the scale of pyrolysis is increased to 15 million tons, and the coal tar industry chain is expanded to produce downstream products derived from aromatics and arylenes.
