石膏矿种对制取硫酸钾工艺的影响

The Influence of Gypsum Type on Production of Potassium Sulphate

本文研究了不同种类天然石膏对石膏转化氯化钾制取无氯钾肥硫酸钾的影响,结果表明:天然石膏纯度越高,氯化钾转化率也相应提高。

In conversion of gypsum and potassium chloride to potassium sulphate, the influence of varieties of natural gypsum is studied in this paper.The tests show: the higher the purity of natural gypsum is, the higher potassium chloride conversion field is.
