摘要
在湿法磷酸生产中要排出大量的磷石膏废渣 ,不仅要占用大量土地堆放而且污染环境。作者介绍了以磷石膏废渣作原料 ,生产硫酸钾铵的 3 0 0 0t a中间试验装置 。
A large amount of phosphogypsum residue is to be discharged during wet phosphoric acid production,which not only occupies a lot of land for piling up but also pollutes the environment.The author describes the production of ammonium potassium sulfate from phosphogypsum residue in a pilot plant of 3 000 t/a,including the double decomposition reaction of phosphogypsum with ammonium carbonate to give ammonium sulfate and that of ammonium sulfate with KCl to produce ammonium potassium sulfate.
