Development and planning of phosphogypsum industry in Wengfu Group area

介绍了瓮福集团区域内磷石膏产业发展概况。通过引进合作和自主创新,瓮福集团区城内正在建设400 kt/a磷石膏制水泥缓凝剂、3.0×10~7 m^2/a磷石行制纸面石膏板、1.0×10~8块/a磷石膏制砖、250 kt/a磷石膏化学转化制硫酸铵联产150 kt/a高纯度氧化钙等项目;今后还将建设磷石膏制硫酸联产氧化钙等项目,并推广应用新型墙体结构建筑体系。预计到"十二五"末期,瓮福集团区域内磷百膏资源化利用率将达到95%。

Development of phosphogypsum industry in Wengfu Group area are described.Through cooperation and innovation,some phosphogypsum-based plants are under construction in Wengfu Group,including 400 kt/a cement retarder,3.0×10~7 m^2/a plasterboard,1.0×10~8 pieces/a gypsum brick,and co-production of 250 kt/a ammonium sulphate and 150 kt/a high-purity calcium oxide.More co-production plants of sulphuric acid and calcium oxide will be built and application of new wall structure building system will be popularized in the future. It is predicted that the utilization of phosphogypsum in Wengfu Group area will reach to 95%by the end of Twelfth Five-Year Plan.
