What does the NRTL model look like? Determination of boundaries for different fluid phase equilibrium regions (Boundaries_LL_NRTL GUI)

A new research paper has been published regarding the possibilities and limitations of the nonrandom two-liquids (NRTL) model for reproducing different kinds of fluid phase equilibria (AIChE Journal. 2022;e17805. DOI: 10.1002/aic.17805). This paper references 3 graphical user interfaces (GUIs), publicly … Continue reading
