Web15 jul. 2014 · The nonrandom two-liquid (NRTL) model is an activity coefficient model used widely in phase equilibria calculations. The NRTL model has three adjustable parameters that are determined through regression of experimental data for a specific system. WebThermodynamic analysis of models of liquid solutions is carried out on the basis of the concentration dependences of excess functions. Using the energy balance plane, the applicability region of the nonrandom two-liquid (NRTL) equation is determined and constraints on the equation parameters are imposed.
