Vapor–Liquid Equilibria Study of the LiCl + CaCl(2) + H(2)O System

[Image: see text] Vapor–liquid equilibrium (VLE) data are measured and reported for the LiCl + CaCl(2) + H(2)O system. The experimental procedures were carried out with pressures between 6 and 101.3 kPa in a computer-controlled glass apparatus. We obtained the relationship between solubility of salt and vapor pressure by analyzing and summarizing the results. Then, a modified NRTL model based on the hypothesis of hydration was used in this paper. By correlation of literature and experimental data for LiCl + H(2)O, CaCl(2) + H(2)O, and LiCl + CaCl(2) + H(2)O (pressure spanning from 5 to 101.3 kPa), some parameters were modified for improving the accuracy of the calculation. Meanwhile, the model was successfully applied to predict the VLE data in LiCl + CaCl(2) + H(2)O systems with the modified binary parameters.
