Gas hydrates are crystalline compounds formed by enclathration of guest molecules into lattice structure of hydrogen-bonded water molecules. These solid crystals could be used as a storage/transportation medium for various gases, also separation of mixture gas, CO2 sequestration, seawater desalination because they can store a large amount of gas within a small volume of the solid crystal. Until now, lab-scale apparatus for measuring gas hydrate formation kinetics and thermodynamic phase equilibrium were developed. In this study, the apparatus for 1 ton/day-scale was developed for gas hydrate formation-dehydration to apply gas transport and storage. Additionally, gas hydrate structure and molecular behavior were analyzed by Raman spectroscope and solid-state NMR spectrometer using dehydrated gas hydrate pellets. |
