On the Development of a Modified Nonelectrolyte NRTL-NRF Model for Strong and Weak Electrolyte Solutions [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2021 The non-electrolyte NRTL-NRF model has been modified to study electrolyte solutions. The modified model for electrolytes is composed of short-range parts expressed by the modified nonelectrolyte NRTL-NRF and the Pitzer-Debye-Hückel equation to represent ...

Modeling dissociation of ionic liquids with electrolyte NRTL model [PDF]
Journal of Molecular Liquids, 2021 Abstract Dissociation of ionic liquids (ILs) is critical to electrochemical process performance by affecting ionic conductivity. Prior studies of thermodynamic modeling either assumed no dissociation or complete dissociation that were not consistent with experimental observations. This work presented an eNRTL model for three aqueous imidazolium-based

Modeling Liquid−Liquid Equilibrium of Ionic Liquid Systems with NRTL, Electrolyte-NRTL, and UNIQUAC [PDF]
Industrial & Engineering Chemistry Research, 2007 Characterization of liquid−liquid equilibrium (LLE) in systems that contain ionic liquids (ILs) is important in evaluating ILs as candidates for replacing traditional extraction and separation solvents. Although an increasing amount of experimental LLE data is becoming available, comprehensive coverage of ternary liquid-phase behavior via experimental ...

Modeling of Solid-Liquid Equilibria Using a Group Based NRTL Equation
Chemical Engineering Transactions, 2015 The NRTL equation has shown great capabilities in predicting phase equilibria data. However its major drawback is the non-availability of the required molecular interaction parameters. Consequently in the present study a new approach is proposed based on

Polyphenol Liquid–Liquid Extraction Process Development Using NRTL-SAC [PDF]
Industrial & Engineering Chemistry Research, 2018 Liquid-liquid extraction (LLE) can be an effective strategy for the purification of polyphenols from a fermentation broth. However, solvents need to be chosen to ensure high extraction capacity and selectivity. For that purpose, a systematic study is here presented, where the partition of different polyphenols-naringin, naringenin, p-coumaric acid, and
