Abstract: Introduced vapor-liquid equilibrium data consistency test of the importance of vapor-liquid equilibrium data used in forecasting the state of law and the activity coefficient equation model, including Van Laar model Margules model, Wilson model, UNIQUAC model briefly summarized , a detailed overview of the consistency test of two models that test the model with the point size test model to compare their respective advantages and disadvantages. In this paper, vapor-liquid equilibrium model of consistency test for the study, select the VB compiler program to compile software visualization interface, and powerful computing power to call the MATLAB function library, the establishment of consistency of vapor-liquid equilibrium testing procedures for the vapor-liquid balance of data consistency check.
Key words: Vapor-liquid equilibrium; thermodynamic consistency test; VB compiler program
