“…erupting and rising above the immersed gas bubble, which however preserved its integrity. Our results of the Gemini AOT surfactant (compared to that of SDS) as regards CH 4 hydrate formation complement those by Kwon et al (2011) and by Salako et al, 2013, who point to a superior performance of Gemini surfactants.…”

International audienceThe morphology and growth of gas hydrate at the interface between an aqueous solution and gaseous mixtures of CO2 and CH4 are observed by means of a simple experimental procedure, in which hydrate formation is triggered at the top of a sessile water drop by contact with another piece of gas hydrate and the ensuing hydrate growth is video-monitored. The aqueous solution is either pure water or a solution of a nonionic or anionic surfactant at low concentration (in the 100-1000ppmw range). In agreement with previously published data, hydrates formed from pure water and aqueous solutions of non-ionic surfactant grow rapidly as a low-permeable polycrystalline crust along the water/gas interface, which then inhibits further growth in a direction perpendicular to the interface. Lateral growth rates increase strongly with subcooling and CO2 content in the gas mixture. Similar lateral growth rates, but varying morphologies, are observed with the non-ionic surfactants tested. In contrast, the two anionic surfactants tested, sodium dodecyl sulfate (SDS) and dioctyl sodium sulfosuccinate (AOT), promote in the presence of CH4 (but not in the presence of CO2) a rapid and full conversion of the water drop into hydrate through a 'capillary-driven' growth process. Insights are given into this process, which is observed with AOT for an unprecedented low concentration of 100ppmw

“…However, the present study implies that a very small amount of BMIM-PF 6 seems to change the interfacial energy between guest molecules and precursor or initial hydrate particles without the change of the activation energy for overall methane hydrate formation, which results in the increase of frequency factor for Arrhenius plot. This mechanism of acceleration of methane hydrate formation is similar to that of general surfactant molecules (Kwon et al, 2011).…”

“…Therefore, an increase in formation rate and storage capacity is essential in hydrate research. Researchers have used additives and promoters to enhance the formation rate and capacity (Kwona et al, 2011;Lee et al, 2010;Ganji et al, 2007). Lee et al (2007) investigated the effect of some cationic starches on the hydrate formation rate of methane mixture with the other natural gas components.…”
