摘要:

磷石膏制酸是我国实现磷化工固废资源化利用、保障硫资源自主可控的核心技术路径,在破解磷石膏大宗固废堆存难题、保障硫资源安全、推动产业绿色转型中发挥了关键作用。近年来,我国磷石膏制酸行业实现了技术工艺迭代、产能规模扩张与产业格局优化,第三代干法工艺实现了工业化稳定运行,百万吨级装置成为行业主流配置。但同时,行业也面临硫黄价格不稳定、副产的水泥熟料市场消纳矛盾突出、核心技术仍存在瓶颈、行业标准体系不完善、低碳属性界定不清晰等问题。“十五五”时期是我国固废资源化与化工产业高质量发展的关键阶段,在“双碳”目标与大宗固废及再生资源高效利用政策的双重导向下,磷石膏制酸行业需精准对接产业发展战略,聚焦产能优化、技术升级、产品多元化、产业协同四大核心方向,推动产业向工艺低碳化、产品高值化、管理智能化、协同一体化转型。系统分析了我国磷石膏制酸行业的发展现状与核心瓶颈,结合“十五五”规划要求及行业发展趋势,提出针对性的发展路径与保障措施,以期为行业高质量发展提供理论参考与实践指引。

Abstract:

Phosphogypsum-to-sulfuric acid is recognized as a core technological pathway in China for realizing the resource utilization of solid waste in the phosphorus chemical industry and for ensuring the autonomous controllability of sulfur resources. It plays a critical role in resolving the stockpiling challenges of bulk phosphogypsum solid waste, safeguarding sulfur resource security, and promoting the green transformation of the industry. In recent years, the phosphogypsum-to-sulfuric acid industry in China has achieved technological and process iteration, capacity scale expansion, and industrial pattern optimization. The third-generation dry process has realized stable industrial operation, and million-ton-scale units have become the mainstream configuration in the industry. Nevertheless, the industry is also confronted with several challenges, including unstable sulfur prices, prominent contradictions in the market absorption of by-product cement clinker, persistent bottlenecks in core technologies, incomplete industry standard systems, and unclear definitions of low-carbon attributes. The 15th Five-Year Plan period represents a critical stage for the high-quality development of solid waste resource utilization and the chemical industry in China. Under the dual guidance of the "carbon peaking and carbon neutrality" goals and policies promoting the efficient utilization of bulk solid waste and renewable resources, the phosphogypsum-to-sulfuric acid industry is required to precisely align with industrial development strategies, focusing on four core directions: capacity optimization, technological upgrading, product diversification, and industrial synergy, and to advance the industrial transformation toward low-carbon processes, high-value products, intelligent management, and integrated synergy. A systematic analysis of the current development status and core bottlenecks of China′s phosphogypsum-to-sulfuric acid industry is provided. Based on the requirements of the 15th Five-Year Plan and industry development trends, targeted development pathways and safeguard measures are proposed, with the aim of providing theoretical references and practical guidance for the high-quality development of the industry.
