SF6 gas has been widely used as an insulating, cleaning and covering gas due to its outstanding insulating feature and because of its inert properties. However, the global warming potential of SF6 gas is extremely high relative to typical global warming gases such as CO2, CFCs, and CH4. For these reasons, it is necessary to separate and collect waste SF6 gas. In this study, the effects of a surfactant (Tween) on the formation rate of SF6 gas hydrates were investigated. The SF6 gas hydrate formation rate increased with the addition of Tween and showed a nearly 6.5 times faster hydrate formation rate with an addition of 0.2 wt.% Tween compared to an addition of pure water. This is believed to be due to the increased solubility of SF6 gas with the addition of the surfactant. It was also found that SF6 gas hydrate in the surfactant solution showed two-stage hydrate formation rates with a formation rate that increased rapidly in the 2nd stage.
