Elucidation of rapid methane- tetrahydrofuran hydrate formation kinetics: Applicable to gas storage

Methane storage as solidified natural gas (SNG) in the form of clathrate hydrates is an emerging, economically feasible and environmentally benign technology. Mixed methane (CH4) - tetrahydrofuran (THF) hydrates offer a paradigm shift to milder storage conditions and faster hydrate formation kinetics, providing a promising scenario to scale up the SNG technology. In this work, we synthesize mixed THF-CH4 hydrates in a high pressure micro-differential scanning calorimeter (HP μ-DSC) to validate the two-step mechanism of rapid mixed THF-CH4 hydrate formation identifying the synergism between them. The two step-mechanism of mixed THF-CH4 hydrate formation was further confirmed by pressure-temperature profile and visual observations with a sample volume scale-up of about 350 times to that of μ-DSC data.
