缔置法生产无氯钾肥——硫酸钾

Production of Chlorine Free Potassic Fertilizer Potassium Sulfate by Association Displacement Process

用缔置法生产硫酸钾的主要原料是氨、氯化钾、硫酸和９２０＃溶剂，其反应条件较温和、易控制，反应媒体可循环使用，无环境污染，有较好的发展前景及经济效益。

The main raw materials for the production of potassium sulfate by the association displacement process are ammonia, potassium chloride, sulfuric acid and 920 solvent. The reaction conditions are mild and easy to control, the reaction media can be recycled, without environmental pollution, so the process has a bright future and good economic benefit.
