Ionic liquid which melts below 100℃ can be applied to various industries because of unique diverse physical, chemical properties. Combination cation and anion of ionic liquids can change depending on purpose as designer solvents. This study focuses ionic liquids on soluble of CO2 favorably. The CO2 capturing technology in CCS (Carbon capture and storage) needs to separate CO2 into other gases. Amine compound is generally used as CO2-absorbing solvents in almost every industrial process. But these amine-solvents have several problems such as toxicity, corrosiveness, etc. Recently ionic liquids are received attention as new CO2 absorbing solvent. Therefore, it is important to gather a lot of data about solubility of CO2 in many different ionic liquids. The Solubility of CO2 in ILs has been experimentally studied for development of a separation process of mixed gas containing CO2. The range of temperature for the experimental measurements is from 303.15 K to 373.15 K. The experimental (CO2 +ionic liquid) data were correlated with Peng-Robinson equation of state (PR-EoS). |
