| 中文摘要: |
| 实验研究了利用磷石膏废渣生产硫酸钾和氯化铵的新工艺 .所用原料还包括碳酸氢铵和氯化钾 ,副产物为碳酸钙和氯化铵 .该工艺流程短 ,操作简单 ,成本低 ,产品质量好 ,K+ 的收率大于 88.2 3% ,产品中硫酸钾的含量大于 92 .1 0 % . |
| 英文摘要: |
| A new process of producing potassium sulfate and ammonium chloride with waste phosphogypsum has been developed. The other raw materials includes ammonium bicarbonate and potassium chloride. Calcium carbonate and ammonium chloride are produced as by-products. The flow has advantages of short range,easy operation,lower cost and a better quality of production. The conversion of K + was more than 88.23% and the production content of potassium sulfate was more than 92.10%. |
