  7. Abstract:
  8. Inrecent years,research onionic liquidsarehighly developed. Because ofthe uniqueproperties ofionic liquidssuch asnegligiblevapor pressureandthermalstability for use inlarge areasofmajor industries have been considered.However,ionic liquids because they have lessenvironmental wasteas an alternative to convention alorganic solventssuch asaminesalkanolanarise.Ionic liquid sassolventsfor theremoval ofacid gases such as water and gasare investigated. The solubility of CO2 and H2S in the [Emim] [OTF] (1-ethyl-3-methylimidazolium triflate) in the temperature range 303.15 to 343.15 K and pressures up to 2 MPa has been studied experimentally. In order to capture modeling, the model equations of state Pitzer, Redlich-Kwong-shiflet, Yokuzeki and Redlich-Kwong-Aspen is used.Also,to evaluate the predictive ability of the Redlich-Kwong-Aspenequation experimental data provided by Shiflett forCO2+ H2Ssolubilityin[bmim] [PF6] andCO2+H2Ssolubilityin[Omim] [TF2N] provided by Jalili, Safavi and colleagues, are used. Finally, theabsorptionrate and selectivity of[Emim] [OTF]and sulfolane (which isanorganic solvent)forCO2andH2Sas solutes are compared with each other. In order to simulate CO2andH2S separation process,Aspen software isused and theability of sulfolaneand [Emim] [OTF]are evaluated
