Abstract

Over 13 trillion cubic feet of natural gas reserves in the world presence of high carbon dioxide (CO2) contents and the removal of CO2 becomes an essential process in order to sustain the performance of the downstream plant as well as the environment. Ionic liquids are proving to be increasingly promising as viable media for not only potentially ‘green’ synthesis and separation mechanism, but it’s also have a novel applications, where it wide range of potential cation and anion elements can be exploit for the specific task. In this study, imidazolium based ionic liquid has been chose for the synthesis and CO2 solubility analysis. Specifically, 1-hexyl-3-methylimidazolium acetate, [hmim][Ac] and 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide were used for this study. These ionic liquids were synthesized based on quaternization and metathesis technique. The result showed the magnitude of CO2 solubility for both ionic liquids using isochoric saturation technique. The solubility of CO2 in ionic liquids was determined by calculating the mol. fraction of CO2 as well as the Henry’s law constant. Consequently, [hmim][Tf2N] gives the higher magnitude for CO2 solubility compared to [hmim][Ac] since it was influenced by fluorinated anion.
