摘要
在分析我国近年磷石膏利用现状的基础上,提出磷石膏制酸是磷石膏规模化利用的途径。通过对我国磷石膏制酸专利的综述,提出了硫磺还原磷石膏制酸的新途径,最后详细比较了硫磺还原相比焦炭还原制硫酸的技术优势。
Based on the analysis of the current situation of comprehensive utilization of phosphogypsum（PC,） in recent years, sulfuric acid production from PG is considered as the approach for utilizing PG in a large scale. The Chinese patents about the sulfuric acid production from PG are reviewed. The new process of the production of sulfuric acid by reducing PG with sulfur is put forward. The technical advantages of the processes reduced by sulfur and coke are compared in detail. The results suggest that the former process has more promising application in the production of sulfuric acid for PG.
