Abstract: In a similar way to the previous Graphical User Interface (GUI) developed to systematically check the consistency of LLE data correlation results, GMcal_TieLinesLL v.2.2 [], this second Graphical User Interface (Boundaries_LL_NRTL) has been developed as a friendly tool for the analysis of the NRTL model, and it is directly related with the paper: “What does the NRTL model look like? Determination of boundaries for different equilibrium regions” (2022, in revision). This GUI allows the direct visualization and calculation of 3D representations and 2D projections of binary spinodal surfaces, LLE maps and miscibility boundaries of the NRTL model for different values of the non-randomness parameter (αij) between 0 and 0.95. The analysis of all these figures allows to reserchers involved in the correlation of experimental liquid-liquid equilibrium data, to establish relations between the tipology of the system under sutdy (regarding the behaviour of all the binary subsystems) and the values of the NRTL binary interaction parameters consistent with that tipology.
