heal.abstract	This paper examines the performance of methodologies and computational tools commonly used in the prediction of phase equilibria of mixtures in typical temperature and pressure range, at hyperbaric conditions. VLE and PVT data of binary and synthetic multicomponent mixtures up to 2000 bar are used. Correlated and prediction results are presented with the translated Peng-Robinson (t-mPR) EoS and EoS/GE models. Correlation of high pressure VLE data is possible with one kij value for systems where Tc,Pc and ω experimental values are available. Predicted kij values for high asymmetric systems with hydrocarbons of Nc>20 are totally unacceptable at high pressure region. There is a great uncertainty on the critical properties and the acentric factor of hydrocarbons with Nc>20 and the relative importance of these parameters is very significant at high pressure conditions. Volume translation is essential for PVT predictions. Temperature independent correlations give very satisfactory results. LCVM, although it provides the best results of the EoS/GE models studied, suffers at high pressures.	en
