本文介绍一种新的硫酸铵转化法制取硫酸钾工艺，该工艺主要特点是原料氯化钾与硫酸铵预先分别制成高温饱和溶液后再混合反应，并加入催化剂进行催化反应。和国内现生产工艺相比，设备更简单，操作更方便，生产周期缩短一半以上，产品质量好，钾收率提高１５ ％ 以上。 This article describes a new ammonium sulfate conversion process for the production of potassium sulfate process, the main features of the process is the raw material potassium chloride and ammonium sulfate pre-made high-temperature saturation solution before mixing reaction, and adding a catalyst for catalytic reactions. Compared with the current domestic production process, the equipment is simpler, the operation is more convenient, the production cycle is shortened by more than half, the product quality is good, the potassium yield is increased by more than 15%.
