Preservation using hydrates as a storage medium is the only technology that enables long-term and high-concentration O3 preservation. This study reports the visual observations of the crystal growth of O3-containing hydrate for the process design of the hydrate production plant. We conducted experiments with the feed gas involving O3, O2, and CO2 in the molar ratio of O3:O2:CO2 = 3.4:42.0:52.6. During observations, O3 in the mixed gas remained at 1.31–2.43 mol %, which is comparable to those of the previous experiments. The observed results of hydrate crystal growth dynamics were classified into two types, which are lateral growth along the gas/water interface and growth into the bulk of the liquid water phase. Crystal morphology varied from polygonal to columnar, dendritic, or haze like with increasing subcooling temperature relative to equilibrium. The diversity of the crystal morphology of O3-containing hydrate was comparable to those of O2 + CO2 hydrate and CO2 hydrate. The implications of the obtained results for the operating conditions of an O3-containing hydrate production plant are discussed.

臭氧笼形水合物的晶体生长：对臭氧保存的意义
使用水合物作为存储介质进行保存是唯一可以长期，高浓度保存O 3的技术。这项研究报告了用于水合物生产工厂工艺设计的含O 3的水合物晶体生长的肉眼观察。我们用包含O 3，O 2和CO 2的进料气以O 3：O 2：CO 2的摩尔比= 3.4：42.0：52.6进行了实验。在观察期间，O 3混合气体中的残留量保持在1.31-2.43 mol％，与之前的实验相当。水合物晶体生长动力学的观察结果分为两种类型，即沿气/水界面的横向生长和向大部分液相的生长。晶体形态从多边形到柱状，树枝状或雾状，随着相对于平衡的过冷温度的升高而变化。含O 3的水合物的晶体形态的多样性与O 2 + CO 2的水合物和CO 2的水合物的晶体形态的多样性相当。讨论了所得结果对含O 3的水合物生产装置的运行条件的影响。
