- Abstract
- I-2 crystallization could be a technical option in HI decomposition section of SI thermochemical water splitting process to increase process efficiency. Design of a crystallizer requires experimental data as well as corresponding equations for thermophysical properties of HI (x) solution, which is a named ternary solution of H2O, HI, and I-2. However, so far, there are no available analyses on them. We collected experimental data and corresponding equations with temperature parameters and compared the equations with the data to analyze their accuracy and credibility. Thermal conductivity was updated in this work while keeping a structure of a corresponding equation. Relative deviations were estimated for liquid density, thermal conductivity, viscosity, and heat capacity and summarized with temperature for H2O, HI, and I-2. Solution density and viscosity of binary H2O-HI solution were also analyzed with an empirical equation under a limited condition and with predictable methods exhibiting satisfactory consistency.
