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 199 was obtained for the used il
