On November 6, the signing ceremony of three phosphorus chemical project design contracts of Guizhou Shengyang Chemical Co., Ltd., affiliated to Shengwei Group, was held in Donghua Company of China Chemical Engineering. Zhao Lei, Chairman of Shengwei Group, Meng Chenzhou, Deputy Secretary of the Party Committee and General Manager of China Chemical Engineering Donghua Company, and Yin Zhaofei, Deputy Secretary of the Party Committee of Hefei Cement Research and Design Institute Co., Ltd. attended the signing ceremony.
At the meeting, Donghua Company, Hefei Cement Institute Consortium and Guizhou Shengyang Chemical signed a design contract for 700000 tons/year phosphogypsum acid production project. At the same time, Guizhou Engineering Company affiliated to Donghua Company and Guizhou Shengyang Chemical signed a design contract for 200000 tons/year semi-water-anhydrous wet phosphoric acid project and 400000 tons/year feed-grade calcium dihydrogen phosphate plant project.
Zhao Lei highly praised the comprehensive strength of Donghua Company and Hefei Cement Institute, and introduced the strategic development prospect and industrial layout of Shengwei Group. She said that the signing of the contract was an important measure for Shengwei Group to implement the closed-loop industrial chain model of "integration of mineralization", and hoped that all parties would strengthen professional cooperation and jointly promote the orderly development of project design.
Meng Chenzhou thanked Shengwei Group and Guizhou Shengyang Chemical for their trust in Donghua Company. He said that the two sides have established a deep friendship in the cooperation of several phosphogypsum projects, and Donghua Company will do its best in engineering design and technical services, ensure the smooth progress of the follow-up construction of the project with high-quality design, and contribute to the resource utilization of phosphogypsum and the transformation and upgrading of the phosphorus chemical industry.
Yin Zhaofei introduced the advantages of Hefei Cement Institute in building materials research, engineering design and equipment. He said that Hefei Cement Institute will cooperate with Donghua Company to give full play to their respective professional advantages and jointly serve the construction of Guizhou Shengyang Chemical Phosphogypsum Acid Production Project. Located in Shuanglong Industrial Park, Fuquan City, Guizhou Province,
Guizhou Shengyang Chemical "Mineralization Integration" Recycling Industry Project is committed to building a first-class production base of new energy materials and high-end fine phosphate in China. The three contracted projects are an important part of the first phase of the project. Among them, the project of producing sulfuric acid from phosphogypsum produces sulfuric acid by recovering sulfur resources, and uses solid products to produce cement clinker ; the project of wet phosphoric acid adopts semi-hydrated and anhydrous process, which can produce high concentration phosphoric acid, and transform semi-hydrated gypsum into anhydrous gypsum with low phosphorus, fluorine and total water content; Feed grade monocalcium phosphate plant adopts slurry granulation process, which will help Guizhou Shengyang Chemical to expand the product line of feed additives. The implementation of the three projects can rely on the existing product system of Shuanglong Industrial Park to realize the comprehensive coupling of "titanium, phosphorus, sulfur, iron and fluorine", promote the efficient recycling of existing resources and enhance the comprehensive utilization efficiency of resources.
From December 3 to 4, China Cement Network will hold the 16th China Cement Energy Conservation and Environmental Protection Technology Exchange Conference and the 1st Solid Waste Comprehensive Utilization and Fluidized Solidified Soil Development Conference in Wuhan, Hubei Province. At that time, Lv Tianbao, the chief technical specialist, former chairman and party secretary of Lubei Chemical, the first domestic phosphogypsum-based acid co-production cement clinker project, will come to the scene to share the key points of phosphogypsum-based acid co-production cement clinker process and industrial practice experience, please pay attention.
