一种以氯化钾或氯化铵或氯化钾和氯化铵为原料生产无氯复合肥的方法 ,其特征是以氯化钾或氯化铵或氯化钾和氯化铵与硫酸反应 ,释放完氯化氢后 ,生成物再和或不和硫酸一起去酸解磷矿粉从而制得无氯的复合肥 ,复合肥的氮、磷、钾含量可以调节。本发明工艺过程简短 ,所需投资少 ,? A method for producing chlorine-free compound fertilizer by using potassium chloride or ammonium chloride or potassium chloride and ammonium chloride as raw materials is characterized in that potassium chloride or ammonium chloride or potassium chloride and ammonium chloride are reacted with sulfuric acid , After the release of hydrogen chloride, the resultant and then with or without sulfuric acid to deacidite phosphate rock to produce chlorine-free compound fertilizer, nitrogen, phosphorus and potassium compound fertilizer can be adjusted. The invention has the advantages of short process, less investment,
