Development of vapor pressure measurement method with static vapor pressure apparatus for high-corrosion solutions under high-pressure

Takai, Toshihide ; Kubo, Shinji

Concerning the iodine-sulfur thermochemical water-splitting process, expanding range of the properties of the HI-I $_{2}$ -H $_{2}$ O system (HI $_{x}$ ) is essential for designing distillation columns and for making good choices of operating conditions. A measurement method with a static vapor pressure apparatus was developed for determining vapor pressure of high-temperature and high-pressure HI $_{x}$ (up to 3 MPa and 160 $^{circ}$ C). Preliminary tests employing the pressure gauge for the sample chamber were carried out for comparisons of the direct pressure values and the indirect values. The results of the test using sample solutions of water, HI-H $_{2}$ O system, and HI $_{x}$ showed the two sets of data accorded well, so that the practicability of this vapor pressure measurement method is validated.
