摘要
在磷铵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且污染环境。笔者介绍了以磷石膏废渣作原料生产硫酸钾铵的３０００ｔ／ａ中间试验装置。
In ammonium phosphate production a large quantity of waste phosphogypsum is to be discharged, 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 waste phosphogypsum 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 potassium chloride to produce ammonium potassium sulfate.
