CO2 solubility in the aqueous 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([emim][Tf2N]) and monoethanolamine (MEA) solutions

Majid Majeed Akbar

Abstract


Ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([emim][Tf2N]) was mixed with 15% aqueous monoethanolamine solution at different concentrations (5 to 15 wt %). The CO2 solubility in these solutions was measured by using pressure drop method at T = 298.15 K. The effect of IL’s concentration of CO2 absorption was discussed.
