ABSTRACT
Isothermal (P, T, x, y) data have been measured for the binary system carbon dioxide + 1-propanol at temperatures from (293.15 to 353.15) K. The pressure range under investigation was between (0.61 and 12.64) MPa. The new experimental results are discussed and compared with available literature data. Measured vapor-liquid equilibria (VLE) data and literature data for the carbon dioxide + 1-propanol system were modeled with a general cubic equation of state (GEOS) using classical van der Waals (two-parameters conventional mixing rule, 2PCMR) mixing rules. A single set of interaction parameters, representing well the critical pressure maximum (CPM) and the temperature of the upper critical end point (UCEP), was used to calculate the global phase behavior in the binary mixture carbon dioxide + 1-propanol in a wide range of temperatures [(293.15 to 426.68) K]. The VLE data are satisfactorily predicted for engineering purposes.
