Modeling of H2S solubility in ionic liquid 1-Ethyl-3-methylimidazolium acetate using mHKM-CPA EoS combined with RETM

In current work, modified HKM Plus Association (mHKM-CPA) EoS together with the Reaction Equilibrium Thermodynamic Model (RETM) was employed to correlate H2S solubility in IL 1-Ethyl-3-methylimidazolium acetate. The RETM proposes an AB2 type reaction mechanism between IL (B) and H2S (A) in the liquid phase. Moreover mHKM-CPA EoS contributes for VLE calculations. H2S and the IL, as association components, assumed to follow 4C and 2B association schemes respectively. After pure components parameters calculation using mHKM-CPA EoS, the binary system was investigated applying RETM. For the system, AAD% equal to 1.99 was obtained for the used IL.
