介绍云南省磷复肥及硫酸“十二五”行业状况:产量增幅趋缓,品种结构趋优,市场适应能力增强;技术创新和转型升级多亮点;磷矿资源贫化影响湿法磷酸精制和优质磷酸二铵生产,磷石膏安全堆存和综合利用制约磷酸生产,企业经济效益普遍下滑。提出“十三五”发展思路:适度调整制酸原料结构,逐步减少对进口硫黄的依赖;稳定磷复肥工业总产能,控制其总产量;加快半水-二水工艺产业化;做强做优磷矿浮选;推进磷石膏安全堆存和综合利用;培育新增点,提升企业经济效益。
Introduction of Phosphate Compound Fertilizers and Sulfuric Acid in Yunnan Province Industry Situation: Output growth slowed down, the structure of varieties was getting better, market adaptability was enhanced, technological innovation and transformation and upgrading were more bright spots, and phosphate resource depletion affected wet-process phosphoric acid Refined and high-quality diammonium phosphate production, phosphogypsum safety deposit and comprehensive utilization of phosphate production constraints, the general decline in economic efficiency. Put forward the development idea of “Thirteen-Five-Year Plan”: adjust the structure of acid raw materials moderately and gradually reduce the dependence on imported sulfur; stabilize the total capacity of phosphate compound fertilizer industry and control its total output; accelerate the industrialization of semi-water- Strong phosphate rock flotation; promote safe storage and comprehensive utilization of phosphogypsum; nurture new points to enhance the economic efficiency of enterprises.
