摘要: 在某些定量工艺计算中,很需要多组分水盐体系相图的等水线数据.本文使用Pitzer电解质溶液理论在微机上计算了几个多组分水盐体系25℃相图中的等水线族,并通过例子说明了这种等水线的用途.

Abstract: Isohyrores on the phase diagrams of multicoponent salt-water systems are often necessary in technological design. We obtained 650 points on isohy-drores at 25℃ for Na+, K+, Mg2+/Cl--H2O, 2Na+, Mg2+/2Cl-, SO42--H2O systems by using Pitzers theory of electrolyte solution. These data are useful in estimating saturation point of salt of brine, and mixing process of brines.
