Emission of carbon dioxide (CO2) is possibly the most significant greenhouse gas activity implicated in climate change.

There is a gap in the industrial applied knowledge and data regarding thermodynamic and physical properties of ionic liquids. The objective of this research study is to investigate ionic liquids and their potential for CO2 capture at different concentrations and temperatures. CO2 solubility was obtained using an Intelligent Gravimetric Analyzer (IGA 003, Hiden Analytical) for the following seven ionic liquids: 1,2,3-Tris(diethylamino) cyclopropenylium dicyanamide, 1-Ethyl-3-methylimidazolium L-(+)- lactate, 3-Methyl-1-propylpyridinium bis [(trifluoromethyl) sulfonyl]imide, Ethyldimethylpropylammonium bis(trifluoromethylsulfonyl)imide, 1,2,3-Tris(diethylamino)cyclopropenylium bis(trifluoromethanesulfonyl)imide, 1-(4-Sulfobutyl) -3-methylimidazolium Bis(trifluoromethanesulfonyl)imide, 1-(4-Sulfobutyl)-3-methylimidazolium hydrogen sulfate. Carbon dioxide solubility was obtained at temperatures of 313.15, 323.15 and 333.15K over a pressure range from 100 mbar to 20,000 mbar. The thermodynamic models used to correlate the experimental CO2 solubility included equations of state, such as the Peng-Robinson (PR-EoS), Sove-Redlich-Kwong (SRK) with quadratic mixing rules, and Non-Random Two-Liquid (NRTL) activity coefficient model. Binary interaction parameters were obtained for the correlations. All models produced low values for their average absolute deviations, implying they can satisfactorily describe the solubility of CO2 in ionic liquids. The solubility of CO2 in all the ionic liquids under study, decreased with increasing temperature and increased with increasing pressure. Carbon dioxide solubility decreased in the following order: [TCD][TF2N] > [PMPY][TF2N] > [EMMP][TF2N] > [emim][LACTATE] > [TCD][DCN] > [(CH2)4SO3HMIm][TF2N] > [(CH2)4SO3HMIm] [HSO4]. The three ionic liquids, [TCD][TF2N], [PMPY][TF2N] and [EMMP][TF2N], show promise with respect to CO2 absorption as they have a similar solubility pattern to some ionic liquids published in the literature that are noted for their high solubility, such as [hmim][TF2N], which are comparable in terms of their physical absorption. Furthermore, Henry’s Law constants for CO2 were determined from the ionic liquids. The enthalpies and entropies of absorption were also calculated.","abstract_html":"One of the biggest environmental challenges of our generation is global warming.
