本工艺将氯化钾与硫酸铵预先分别制成高温饱和溶液，然后在加入催化剂条件下进行混合反应，制得质量较好的硫酸钾，副产品为氮钾复合肥。和国内现工艺相比较，工艺设备更简单，操作更方便，生产周期缩短一半以上，钾收率提高15％以上。 In the process, potassium chloride and ammonium sulfate are respectively prepared into high-temperature saturated solution in advance, and then mixed and reacted under the condition of adding the catalyst to obtain better quality potassium sulfate and the by-products are nitrogen and potassium compound fertilizer. Compared with the current domestic craft, the process equipment is simpler, the operation is more convenient, the production cycle is shortened by more than half, and the yield of potassium is increased by more than 15%.
