氯化钾硫酸铵转化法制取硫酸钾工艺的研究

Study on Process for Producing Potassium Sulphate by Conversion Reaction of Potassium Chloride with Ammonium Sulphate

本文介绍了以氯化钾、硫酸铵为原料制备硫酸钾的工艺．通过实验确定了最佳工艺条件，硫酸钾收率达83％，K2O含量50%左右，Cl-含量小于1.5％．

This paper introduces the process with which,using the ammonium sulphate and potassium chloride as the raw material,the potassium sulphate could be produced.Through laboratorial test,thebest technological conditions were presented,potassium sulphate revenue about 83%,the content ofK2O about 50% and the content of CI- under 1.5%.
