Hydrate formation process is a mass transfer process between gas and liquid, which lead to phase change. As the mass transfer efficiency between gas and liquid is low, the hydrate formation rate is slow, as the mass transfer efficacy is low, the amount of consumed gas is small. Therefore, improving the hydrate formation rate and storage capacity is actually improving the efficiency and efficacy of mass transfer between gas and liquid.The variation of hydrate formation rate and storage capacity is studied in static pure water, pure water with stirring, for kinds of surfactants solution and surfactants solution with stirring systems.The promoting mechanism is analyzed from mass transfer. The results showed that hydrate formation rate in system of pure water with stirring is effectively improved but the storage capacity improve not obviously compared with in systems of surfactants solution and surfactants solution with stirring. The reason that surafactants can promote hydrate formation is related to its amphipathicity and ability to adsorb at metal surface. As the surfactants HLB value increase, hydrate formation rate improved but storage capacity decreased slightly. Hydrate formation rate can be further improved in system of surfactants solution with stirring.
