An experimental study of the synergistic effects of BMIM-BF4, BMIM-DCA and TEACl aqueous solutions on methane hydrate formation
Abstract In this work, the effects of three ionic liquids (ILs), namely, 1-butyl-3-methylimidazolium tetrafluoroborate, 1-butyl-3-methylimidazolium dicyanamide and tetraethyl-ammonium chloride, on methane hydrate formation and dissociation kinetic parameters were studied. The kinetic parameters incl...
