On February 5, the pre-distillation tower for Phase 1 of Stage 2 of Shaanxi Coal and Chemical Industry Group Yulin Chemical Co., Ltd.’s 15 million tons per year demonstration project for clean and efficient conversion of coal into various products was successfully installed as an AA-grade distillation unit. Thus, all 20 large-scale equipment lifting tasks scheduled before the Spring Festival were completed ahead of schedule. It is reported that on December 9, 2025, the Air Separation Project Department began the lifting of the first oversized equipment. Faced with multiple challenges such as low winter temperatures and equipment size limitations, the team members worked day and night to overcome these difficulties, successfully lifting and installing 5 distillation towers in the methanol department, as well as 15 air-cooled towers and buffer tanks in the air separation department. With the successful lifting of the 20 large-scale equipment units, Yulin Chemical promptly began working on the lifting plan for the gasification project, facilitating the arrival and assembly of 350-ton and 800-ton heavy cranes, thereby laying a solid foundation for the comprehensive lifting of all 356 large-scale equipment units at the site. The 15 million tons per year demonstration project for the clean and efficient conversion of coal based on differentiated quality, operated by Shaanxi Coal Group Yulin Chemical Co., Ltd., makes full use of the abundant coal resources in the Yulin area. With \"technology for the differentiated use of coal\" as its core, it combines modern coal chemical processes with various compounds from petroleum chemistry through two pathways: coal-to-olefins and coal-to-aromatics. This approach extends the industrial chain, resulting in the production of 45 different products across 4 categories, including high-value-added materials, biodegradable materials, battery electrolyte solvents, and special oils. Upon completion of the project, it is expected to generate annual sales revenue of 134 billion yuan, annual profits of over 30 billion yuan, and create more than 7,000 job opportunities.
