TL;DR: In this paper, the solubilities of inorganic compounds in supercritical water were investigated in the range from (653 to 693) K and from (18 to 23.5) MPa.
Abstract: To increase the available data on systems containing supercritical water and inorganic compounds, an experimental setup was designed to investigate the solubilities of inorganic compounds in supercritical water. In this work, three alkali chloride salts (LiCl, NaCl, KCl) and three alkali nitrate salts (LiNO3, NaNO3, KNO3) were investigated in the range from (653 to 693) K and from (18 to 23.5) MPa. The experimental results were correlated with a model based on the phase equilibrium between the inorganic compound and supercritical water. When available, the experimental data were extended with data available in the open literature. The experimental results and parameters obtained by this model were compared with each other and evaluated under consideration of the physical aspects of the inorganic compounds. In addition to the main purpose of the experiments, side reactions like decomposition of nitrate and changes in pH were observed and discussed in this work. The presented data are the first coherent stu...
