Ozone (O3) has many industrial applications such as in sterilization. One of the long-term O3 preservation methods is molecular storage in clathrate hydrate. In this study, an experimental system was developed for continuously forming O3 + O2 + CO2 hydrates. The parameters that affect the continuous operation of the system and that lead to increases in the concentration of O3 in the hydrates were also experimentally evaluated, implementing the method of quality engineering. After optimizing these operating parameters, the O3 storage capacity in the hydrates was measured to be 0.26 wt % at 2 h of total operation time. By X-ray diffraction, it was found that the produced sample contained hydrates, and long-term preservation for 6 months was possible at the temperature of general freezing warehouses.
