ABSTRACT

Vapor-liquid (VLE), liquid-liquid (LLE), and vapor-liquid-liquid equilibria (VLLE) data for the carbon dioxide + n-pentadecane system at (293.15, 303.15, 313.15, 333.15, and 353.15) K up to 17.50 MPa and phase compositions of the two liquid phases and vapor phase as a function of temperature along the liquid-liquid-vapor (LLV) line are reported. The experimental method used in this work was a static-analytical method with liquid and vapor phase sampling. The new experimental results are discussed and compared with available literature data. Measured data and literature data for the carbon dioxide + n-pentadecane system were modeled with the Soave-Redlich-Kwong (SRK) EoS using classical van der Waals (two-parameter conventional mixing rule, 2PCMR) mixing rules. A single set of interaction parameters was used to predict the complex phase behavior in the binary mixture carbon dioxide + n-pentadecane.
