The Yanchang Group Jingbian Park Coal, Oil, and Gas Resource Comprehensive Conversion Project, the largest energy and chemical project in Shaanxi Province in terms of one-time investment, has commenced construction successfully. The project involves the catalytic thermal cracking of 1.5 million tons of residue to produce 600,000 tons of olefins, as well as the production of 600,000 tons of olefins through the conversion of 1.8 million tons of coal into methanol. In the same year, the 1.8 million-ton coal-to-methanol and 600,000-ton coal-based production project of China Coal Group in Yuheng achieved successful commissioning upon the first feed-in attempt, thereby completing the entire production process smoothly. At present, there are only 4 enterprises in Shaanxi Province that develop the polyolefin industry, namely: Yanchang Group, China National Coal Group, Shaanxi Coal Industry, and Shenhua Group ； Four companies are responsible for producing 1.5 million tons of polyethylene and 1.9 million tons of polypropylene. If we consider only the scale of the polyethylene industry, Shaanxi Province ranks first; even when taking into account the scale of the polypropylene industry as well, Shaanxi Province remains in second place nationwide, behind only Zhejiang Province. At 4 years old, the dark horse from Shaanxi emerged! Of course, there will be more in the future! And double it!
