Abstract

The effect of electrolytes in the temperature profile of saline extractive distillation columns is analyzed using a Newton–Raphson based program (acronym GKTM) with a new increase-bystep technique and applied to the system 1-propanolwater-LiNO3. In addition, the E-NRTL model is examined in order to validate its capability of making accurate predictions of phase equilibrium behavior and its suitability for simulation of extractive distillation columns. Special aspects of the phase equilibrium of mixed solvents electrolyte systems are analyzed. These particular features determine the special temperature profile in these cases.
