Experimental and modelling studies on thermodynamic methane hydrate inhibition in the presence of ionic liquids
This paper presents a series of experimental and modelling studies on the thermodynamic inhibition effects of four ionic liquids on the methane hydrate formation. The investigated ionic liquids are 1-methyl-3-octylimidazolium chloride MOIM-Cl, 1-methylimidazolium hydrogen sulfate H-MIM-HSO4, tetraet...
