Abstract
A suitable slurry composition allows gas hydrates to be stored or transported under metastable conditions. The slurry includes gas hydrate particles and a carrier liquid for the gas hydrate particles. Suitable carrier liquids have a specific gravity in the range from about 0.6 to about 2, a pour point below about -20.degree. C. a viscosity of about 10 centipoise or less, and a thermal conductivity lower than that of the gas hydrate particles. The slurry can be stored or transported in a system that includes a container for holding the slurry; a device for agitating the slurry while in the container (e.g., a mixing blade, a rotating screw, a reciprocating box beam, or an ultrasound generator); a device for removing excess carrier liquid from the container while it is loaded or being loaded with gas hydrates and/or carrier liquid (e.g., a skimming device or a drain); and a device for reslurrifying the gas hydrates with carrier liquid before or during unloading of the gas hydrates from the container (e.g., a carrier liquid injection nozzle).
