ALVAREZ, MIGUEL N; LAM, ELIZABETH J  e  GALVEZ, MARÍA E. LIQUID-VAPOR EQUILIBRIUM IN THE CRITICAL REGION. J. Chil. Chem. Soc. [online]. 2006, vol.51, n.4, pp.1044-1048. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072006000400011.

In the various models existing for the determination of thermodynamic properties, it is common to find references to the difficulties in calculations carried out in the critical region. This situation presents even more problems in relation to calculations related to the saturation zone in the critical region. Experimental measurements in this region also present serious difficulties becauseexperimentalinformation relative to this isscarce. This study presents an analysis of the liquid-vapor equilibrium in the critical region based on the IAPWS-IF97 model, which was determined withexperimental data for water

Palavras-chave : Thermodynamic properties; líquid-vapor equilibrium; crítical region.
