Natural gas storage in hydrates with the presence of promoters

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

“…To overcome the slow kinetics, continuous research efforts have been put forth in improving the kinetics of methane hydrate formation either by innovative reactor designs [14][15][16][17][18][19][20] including the use of different porous media [21][22][23][24][25][26][27][28][29] or the use of kinetic promoters (predominantly surfactants) in order to enhance the rate of hydrate formation [30][31][32][33][34][35]. Though the kinetics of hydrate formation is improved by a choice of suitable reactor or kinetic promoter, there is no reduction of the high energy requirement due to low temperature and high pressure conditions of hydrate formation.…”

Solubility measurement of methane in aqueous solution of sodium dodecyl sulfate at ambient temperature and near hydrate conditions

“…However, there is a common bottleneck with respect to these technologies in that the hydrate formation rate is very low in usual cases. It is well known that hydrate formation can be promoted dramatically by adding low doses of surfactants, such as sodium dodecyl sulfate (SDS) [5][6][7]. However, there exist arguments with respect to the promotion mechanism.…”

“…A large number of investigations reported on the effects of different surfactants in promoting hydrate growth [3][4][5][6][7]. Sodium dodecyl sulfate (SDS) is a typical anionic surfactant that has been used widely as a hydrate promoter [3,[8][9][10][11]. However, the promotion mechanism is not very clear yet.…”
