罗布泊卤水生产硝酸钾半成品工艺研究(二)等温蒸发实验研究

Study on preparation of KNO_3 from the brine in Luobupo (Ⅱ) the isothermal evaporation experiment

本文在前期研究工作的基础上,对新疆罗布泊含硝酸钾卤水进行了25℃等温蒸发实验,获得了两种典型组成卤水在等温蒸发过程中的盐类析出规律及各组分质量分数的变化规律,并与前期进行的相图计算结果进行了比较,两者基本一致,为进一步的工艺实验及该卤水的综合开发利用提供了可靠依据。

Based on the early researches, the isothermal evaporation process(25℃) of the brine in Luobupo Xinjiang was studied. During this process, the crystallization orders of salts for two kinds of typical brine were acquired, and the liquid composition was measured, too. The results of experiment were accord with the ones calculated through the phase diagram well. These works give a dependable basis for the research of technology and comprehensive utilization of the brine in Luobupo Xinjiang.
