Abstract:

Micellar surfactant solutions were found to increase gas hydrate formation rate and storage capacity. An anionic surfactant, namely sodium dodecyl sulfate (SDS) was used to improve hydrate storage capacity of a synthetic natural gas (mol percent of methane, ethane and propane are 92.05%,4.96%, 2.99%, respectively). Hydrate could form quickly in a quiescent system with the presence of SDS. There was a better SDS solution concentration for gas storage in hydrates.
