摘要
溶剂法制硫酸钾 ,是以氯化钾和硫酸为原料 ,用有机溶剂萃取制备硫酸钾 ,制得的硫酸钾达国标ZBG2 10 0 6 - 89优级品的要求。本工艺操作条件温和 ,流程密闭循环 ,基本无“三废” ,投资少 。
Potassium sulfate is manufactured from potassium chloride and sulfuric acid by organic solvent extraction.Potassium sulfate can reach the requirements of high-class product of National Standard of ZBG 21006-89.The operation condition of this technological process is moderate.It is in closed circulation with lower investment and hith quality,and without pollution basically.
