dc.description.abstract |
The emission of CHF3 and C2F6 to the atmosphere should be reduced in order to mitigate the accelerating global warming effect. To examine the feasibility of the gas hydrate-based F-gas capture, the N2 + CHF3 and N2 + C2F6 gas hydrates were investigated with a primary focus on macroscopic thermodynamic conditions, microscopic structural analyses, and gas separation efficiency. The H-LW-V equilibrium lines of both N2 + CHF3 and N2 + C2F6 hydrates were shifted to thermodynamically more stable region as the concentrations of F-gases increased when compared to pure N2 hydrate. The N2 + CHF3 hydrates were revealed to be sI hydrates, whereas the N2 + C2F6 hydrates were found to be sII hydrates through powder X-ray diffraction. Also, the formation process of both N2 + CHF3 and N2 + C2F6 hydrates was monitored using in-situ Raman spectroscopy. Lastly, the efficiency of gas separation was examined through gas chromatography by measuring gas compositions of both vapor and hydrate phases after the completion of hydrate formation. |
