Ionic liquids (ILs), a promising alternative for organic solvent, were found to have the inhibition effect on the CO2 hydrate formation. Among ILs, the hydroxyl groups in [HEMP][BF4], Pyrrolidinium cation based ionic liquids, were found to be very effective inhibitor on hydrate formation. In this study we measured the dissociation temperature of CO2 hydrate containing Ionic liquids including [HEMP][BF4] at constant high pressure and determined loading composition of all components. With 1 ~ 9 weight present of ILs to aqueous solution, three-phase equilibrium conditions in LW-H-LCO2 were determined by varying the relative amount of CO2 to ILs-H2O mixture. The result shows that ILs inhibit the CO2 hydrate formation even with small amount. |
