Modeling of high-pressure vapor–liquid equilibrium in ionic liquids + gas systems using the PRSV equation of state

Modeling vapor liquid equilibrium of ionic liquids + gas binary systems at high pressure with cubic equations of state

“…In this condition, we can note the upward curvature in the isotherms, i.e., the elevation of the pressure entails very little increase in the gas solubility. This behavior was observed in others works in the literature Peters, 2003, 2004;Arce et al, 2010). The solubility of CO 2 in ionic liquids follows a linear relationship with the length of alkyl chain.…”

Equation of state modelling of systems with ionic liquids: Literature review and application with the Cubic Plus Association (CPA) model

“…The results of calculated pressures are only presented in a graphical form. Arce et al [45] modelled the highpressure VLE of 17 binary mixtures of ionic liquid + gas with the Peng-Robinson/Stryjec-Vera EoS, again using the Wong-Sandler mixing rules (with van Laar model) for the gamma-phi approach, and the one-fluid van der Waals mixing rules for the phi-phi approach. Critical properties and acentric factors for some ionic liquids were determined using the group contribution method by Lydersen-Joback-Reid [46], while for other ionic liquids these properties were available from literature.…”

“…In the first of them [45] the authors modelled the high-pressure VLE of 17 binary mixtures of ionic liquid + gas with the Peng-Robinson/Stryjec-Vera EoS, using the Wong-Sandler mixing rules with van Laar. One parameter in the PRSV EoS was fitted using experimental vapour pressure data for the ionic liquids [C 4 The other work that uses experimental vapour pressures of ionic liquids is reference [122].…”

Modeling of ionic liquid+polar solvent mixture molar volumes using a generalized volume translation on the Peng–Robinson equation of state

“…A number of researchers have investigated the ability of equations of state in predicting the molar volumes of pure ionic liquids and their mixtures with other substances. Arce et al [20] examined vaporliquid equilibria in some ionic liquid + gas systems at high temperatures using the Peng-Robinson/Stryjek-Vera (PRSV) equation of state and a number of mixing rules. Yokozeki and Shiflett [21] used the original van der Waals equation of state to study the solubility of different gases in ionic liquids.…”
