摘要

The purpose of this work is to compare two models,which are able to perform Vapor-Liquid Equilibrium (VLE)predictions.The arst one,the LCVM model,is an EoS/GE one and it has been successfully applied in the predictionof the VLE behavior of polar and non-polar systems,as well as,systems of dissimilar component size,such as thosecontaining gases with large F14lkanes.The second one is PHCT,an equation of state based on the perturbed hardchain theory-It has also been successfully applied in binary systems of supercritical EIlids and non-polar moleculesand in systems containing light gases and large n-paramns.The compadsons results presented in this paper,provedthat the two models are comparable,concerning the ability to predict the VLE,as well as,the volumetric behaviorof systems with low to medium component size difTerence(supercriticalallids with non-polar components up to about lOcarbon atoms).However,as the size difference increases,LCVM performs better,especially in the near criticalregion of such system.
