| Research Abstract |
Experiments were performed to visually observe the clathrate hydrate crystal growth at the liquid-liquid or gas-liquid interfaces, thereby investigating the crystalline morphology of the hydrate crystals and the crystal growth rates. Considering the relevance to the natural gas storage/transportation in the form of hydrates and the hydrate-based cool energy storage, cyclopentane, methane, ethane, propane and methane + ethane + propane mixture were used as the guest substances. The analysis on the dependence of the visually observed results on the driving force of the crystal growth revealed the relation between the heat and mass transfer and the hydrate crystal growth.
