Kinetics of methane hydrate formation and its dissociation in presence of non-ionic surfactant Tergitol

Enhanced clathrate hydrate formation kinetics at near ambient temperatures and moderate pressures: Application to natural gas storage

“…Other notable kinetic studies for mixed methane hydrate formation with use of thermodynamic promoters include the formation of mixed methane hydrates in presence of cyclopentane [19,41] and tetrahydrofuran (THF) [2,40,44]. All kinetic studies available on mixed methane hydrate formation at higher temperatures (with and without thermodynamic promoters) have been performed only in stirred tank reactor configuration [45,46].…”

Effect of different fixed bed media on the performance of sodium dodecyl sulfate for hydrate based CO 2 capture

“…More recently, people have investigated the effects of using novel materials such as polyurethane foam and metallic packing as packing media, on hydrate formation [44,51]. The kinetics of hydrate formation can also be enhanced by the use of surfactants such as Sodium Dodecyl Sulfate (SDS) in small doses of the order of ppm as additives [42,[52][53][54][55][56][57][58][59][60][61].…”

Study on methane hydrate formation in gas–water systems with a new compound promoter

“…[13][14][15] In the recent decade, one of the most common methods to promote hydrate formation is adding low-dose chemical additives, most of which are organic liquids and surfactants, including tetrahydrofuran (THF), sodium dodecyl sulfate (SDS), sodium dodecylbenzenesulfonate (SDBS) and nanouid series, etc. [16][17][18][19][20][21] Veluswamy et al 22 studied the effects of 5.6 mol% THF on the kinetics of methane hydrates. They found that under static conditions, the hydrate formation pressure decreased from 6.7 MPa to 2.5 MPa, indicating that a large amount of gas could be stored at moderate pressure.…”
