中文摘要：

氯化钾是我国化肥生产的重要原料,包含氯化钾的无机盐体系的分离过程综合研究具有重要理论意义和应用价值。以NaCl-KCl-H2O体系为例,提出了一种同阴离子双盐体系分离过程的综合方法。该方法是通过分析同阴离子双盐体系的固液平衡关系,在温度的影响和同离子效应的基础上建立的。其利用图解法直接从相图中寻找可行的分离工艺流程,设计过程简便易行。分别给出NaCl-KCl-H2O体系的两个和Mg Cl2-KCl-H2O体系的一个过程综合案例,并给出了相应的工艺流程。

英文摘要：

KCl is the important raw material for fertilizer production in China. The separation process synthesis for the salt-water systems with KCl has important theoretical significance and practical application value. With the example of NaCl-KCl-H2O system, this study has presented a synthesis method for the separation process synthesis of the disalt system with the same anionic. Based on the temperature affect and common-ion effect, this method was built by analyzing the solid-liquid equilibrium. The illustration method were used to determine the separation process form the phase diagram, the design process was very simple and practical. Two synthesis case of NaCl-KCl-H2O system and one of Mg Cl2-KCl-H2O system were given in the paper, respectively, and the corresponding technological processes were also given.
