Investigation of Occupation Behavior of SF6 in SF6 + NaCl Hydrates |
| 초록 |
For practical application of gas hydration in distillation processes, investigation on occupation behavior of guest molecules in the presence of NaCl is essential. Herein, the hydrate phase equilibrium of SF6+Nacl solutions (water + 2, 4 and 10 weight % NaCl) were monitored in the temperature range 277 to 284 K and under pressures of up to 0.1 MPa. Based on equilibrium points, each dissociation heat of SF6 + NaCl hydrates was calculated by Clausis-Clapeyron equations. In addition, structural identification of gas hydrates formed by varying the weigt fraction of NaCl relative to water was performed by both Raman spectrometer and X-ray diffraction. Further evaluation of the temperature-induced release behavior of SF6 in pure and SF6 + 4 wt% NaCl hydrates in the temperature range 140 to 290 K indicated that SF6 rapidly escaped from hydrate cages at near 270 K, which almost corresponds to the dissociation temperature of these hydrates.
