Effect of imidazolium based ionic liquids and ethylene glycol monoethyl ether solutions on the kinetic of methane hydrate formation

In a high pressure reactor, the methane hydrate formation experiments are carried out in the presence of the various imidazolium based ionic liquid solutions with 0.5 wt.% so that the induction time, gas consumption and temperature are measured. Moreover, methane hydrate formation experiments are performed in the presence of ethylene glycol monoethyl ether (EGME) as an inhibitor. The simultaneous effect of EGME and ionic liquid solutions on the methane hydrate formation is investigated so that influence of these materials depends on the type of ionic liquid and the concentration of EGME. The results indicate that using 0.75 wt.% EGME in the presence of [BMIM][MeSO4] and [OH-EMIM][BF4] solutions leads to the promotion of methane hydrate formation. In contrast, these systems with 10 wt.% EGME play as a kinetic inhibitor in methane hydrate formation.
