Guodian Yinglite Group established Yinglite Chemical Co., Ltd. in 2003, and established the development policy of "relying on local superior mineral resources, taking its own power plant as the core of the industrial chain, building high-energy chemical industry, gradually forming an upstream and downstream integrated chain industry, actively developing circular economy and forming the core competitiveness of low-cost expansion", and rationally planning the industrial structure. Shizuishan city, where the company is located, is rich in coal and lime resources, which provides low-cost and sufficient raw materials for the 400MW thermal power unit of the company's annual output of 6.5438+0.4 million tons of refined lime base; The company's annual output is 6.5438+0.4 million tons of fine ash-based and 400MW thermoelectric units to provide electricity and raw materials for calcium carbide production; Self-produced 400,000 tons of calcium carbide provides raw materials for downstream products such as PVC and lime nitrogen, and a large amount of calcium carbide slag slurry produced by calcium carbide production is subjected to flue gas desulfurization treatment in the company's own power plant and Shizuishan power plant. In the company's circular economy industrial chain, on the one hand, it can reduce costs and increase efficiency through industrial circular combination; On the other hand, through the comprehensive utilization of waste water, waste gas and waste residue, clean production is realized and waste is turned into treasure. Finally, an industrial chain based on the advantages of coal resources, power production, PVC and caustic soda production as the core and comprehensive utilization of wastes was formed. The resource advantage and complete industrial chain greatly reduce the cost of raw materials, making the gross profit margin of Guodian Yinglite Group always at the leading level in the same industry.
Vaporization industry chain: lime → thermoelectric → calcium carbide → PVC and caustic soda.
Curing industrial chain: lime → thermoelectric → calcium carbide → lime nitrogen → dicyandiamide.
