Nayong Wangjiaying Qingli Coal Mine
The coal from Qingli Group’s Wangjiaying Coal Mine in Nayong has an average calorific value of 5,000 kcal, making it high-quality coal suitable for power generation. With a current production capacity of 900,000 tons per year, it can generate 2 billion kilowatt-hours of electricity. After communication with Guodian Investment’s Guizhou Jinyuan Group, Wangjiaying Qingli Coal Mine will supply the coal needed for power generation, while Jinyuan Group’s Nayong Second Power Plant—equipped with four 300,000-kW units—will be responsible for organizing power generation under a “direct power supply” model, feeding electricity into the Southern Power Grid system to meet Qingli Group’s chemical product manufacturing needs. According to calculations, the comprehensive cost of generating electricity using self-produced coal is around 0.3 yuan per kilowatt-hour, and adding transmission fees brings the total to about 0.4 yuan per kilowatt-hour—a reduction of roughly 0.2 yuan per kilowatt-hour compared to the electricity prices currently paid by enterprises.
Construct a production facility with an annual capacity of 10,000 tons of elemental fluorine. By electrolyzing anhydrous hydrogen fluoride—produced as a byproduct of 150,000 tons per year of wet-process phosphoric acid—the facility can produce 10,000 tons of elemental fluorine annually (the electrolysis of anhydrous hydrogen fluoride during the production of 10,000 tons of elemental fluorine per year consumes approximately 2 billion kilowatt-hours of electricity). Compared to the fluorite-based process, this technology offers significant cost advantages in producing anhydrous hydrogen fluoride (the cost of the fluorite-based process is about 9,000 to 10,000 yuan per ton, whereas the cost of this new process is roughly 4,000 yuan per ton). Moreover, when combined with the cost advantage of self-generated electricity (which can reduce the cost of producing 10,000 tons of elemental fluorine by 200 million yuan), this process becomes highly attractive for attracting downstream clusters in the fluorine chemical industry.
