摘要
根据硫酸镁在水中溶解度图特点,提出了利用运城盐湖冬季大田生产的粗镁产品制取精制一水合硫酸镁的新工艺,得出了最佳工艺条件,并研究了质量分数为33%的硫酸镁溶液在180℃下的结晶情况。实验表明,该工艺与传统工艺相比,具有流程较短,操作简单,生产成本较低,产品纯度较高等优点。
According to MgSO_(4)-H_(2)O system phase diagram, the process of preparing purified magnesium sulfate monohydrate from crude magnesium sulfate is made.The optimum process conditions are also obtained.The crystallization conditions of 33% magnesium sulfate solution at 180 ℃ are studied.The test results show that the new technology has the advantages of short process,simple operation,low manufacture cost and high quality of the product compared with the traditional technology.
