چکیده انگلیسی
This study was aimed to simulate a new ionic liquids (ILs)-based CO2 capture process which is useful to capture CO2 from model flue gas, by using two promising CO2 absorbents, 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF4]) and 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]). Thermodynamic properties such as vapor pressure, heat capacity and density were modeled. Vapor-liquid equilibrium (VLE) data were calculated by Redlich-Kwong (R-K) equation and NRTL model. The calculated VLE data were in good agreement with the experimental values. This ILs-based CO2 capture process is characterized with few advantages such as there is no issue of water; solvent (ILs) loss is negligible as compared to monoethanolamine (MEA)-based CO2 capture process (e.g., 0.299Â g/tCO2 for [bmim][BF4] and 0.391Â g/tCO2 for [bmim][PF6] respectively, while 178Â g/tCO2 for MEA); potential corrosion risk is excluded; the energy consumption in [bmim][BF4]- and [bmim][PF6]-based processes are lowered up to 26.7% and 24.8% respectively than that in MEA-based process. Thus, such an ILs-based CO2 capture process is more competitive than traditional MEA-based CO2 capture process.
