![]() What does the NRTL model look like? Determination of boundaries for different fluid phase equilibrium regions. The 4 th most cited article published in Fluid Phase Equilibria in 2017-2020 (extracted from Scopus 11/2020). Should we trust all the published LLE correlation parameters in phase equilibria? Necessity of their Assessment Prior to Publication. ** After using this GUI: GMcal_TieLinesLL, please complete the following quick inquiry to know your opinion about the graphical user interface developed: English version // Spanish version. To follow updates and comments: LinkedIn Research Gate Facebook The analysis of LLE binary systems at different temperatures is also possible, including the location, if there exits, of the Critical Solution Temperature (UCST, LCST or Closed Misciblity Loops). The NEW VERSION 2.2 of this friendly tool also allows the analysis of the Hessian Matrix determinant (σ), the spinodal curve (σ=0) and the Plait Point location for LLE ternary systems, using additionally the δ and δ* matrix determinants, which have to be also equal to zero and additionally the miscibility boundaries (for α ij values different from 0.2). In addition, restrictions on NRTL binary parameters have been used in the correlation procedure to guarantee the adequate prediction of the total or partial miscibility behavior of the binary subsystems. This simple analysis could be used by authors and journals in order to guarantee the adequate prediction of equilibrium. The analysis of the G M(L)/RT surface in the whole range of composition, the G M(L)/RT for the binaries subsystems and the G M(L)/RT curves in planes containing the liquid-liquid tie lines should be necessary to validate the obtained parameters for the different models for correlating phase equlibrium data. In this link:, it is possible to acces to a very easy to use Graphical User Interface ( GMcal_TieLinesLL v.2.2) based on the topological information contained in the Gibbs energy of mixing function, that has been developed for binary and ternary LLE systems, as a friendly tool to check the coherence of the parameters obtained in a correlation data procedure (the NRTL and UNIQUAC models are included by defect, however any other G Excess(L)/RT model could be easily implemented).
