Evaluation of Thermodynamic Consistency for Isobaric and Isothermal Binary Vapor-Liquid Equilibrium Data using PAI Test - Alcohol + Hydrocarbons Systems -

Abstract

The thermodynamic consistency of binary vapor-liquid equilibrium data has been examined for 46 binary alcohol + hydrocarbon systems with 323 data sets in total (159 isobaric and 164 isothermal sets) using the PAI test proposed in our previous study. The PAI test permits an overall check of the data by combining three tests: a point test, an area test, and an infinite dilution test. In this work, the PAI test was incorporated with the NRTL equation for fitting data. The results of the PAI test for the vapor-liquid equilibrium data showed that the PAI test was able to select the reliable data effectively.
