Study on fluidizing the highly converted methane hydrate for gas storage and transportation

Study on the Formation Characteristics of CO2 Hydrate and the Rheological Properties of Slurry in a Flow System Containing Surfactants

“…Meshram et al 17 studied the formation experiment of a methane hydrate containing sodium dodecyl benzene sulphonate (SDBS) in a high-pressure reactor and the results showed that the presence of SDBS in aqueous solutions delayed hydrate nucleation and SDBS acted like an anti-agglomerant, suggesting that SDBS could be a suitable additive for flow assurance. Xiao et al 18 proposed that high-concentration anti-agglomerants decrease the formation rate of gas hydrate in water-in-oil (W/O) emulsions and also found low water cut and high Span 20 concentration, particularly the commingled additives, could be solutions for fluidizing highly converted hydrate particles. All the above conclusions indicate that adding a certain amount of antiagglomerants into the systems can effectively prevent the hydrate formation.…”

The synergy of spiral agitation and nano-promoters significantly enhances hydrate formation under mild conditions

“…The question that follows is how to efficiently store and transport natural gas, especially for the remote areas lack of natural gas resource. Gas hydrates are non-stoichiometric compounds composed of water molecules and gas molecules under low-temperature and high-pressure conditions, where gas molecules are packed in the crystal lattices that consist of hydrogen-bonded water molecules 1 . The high storage capacity of about 170 V/V and extraordinary security of hydrates (can be long-term stored under 253.15 K and atmospheric pressure) endow it with great potential in natural gas storage and transportation [2][3][4] .…”
