Abstract

Vapor - liquid equilibrium data have been measured for the ethylene + hexane system at temperatures of (390 to 510) K and pressures up to 10 MPa. The bubble and dew point pressures of ethylene + hexane samples with fixed compositions were measured using the Cailletet apparatus. The critical points of ethylene + hexane mixtures were also measured experimentally. The experimental data were correlated with the modified Sanchez-Lacombe (MSL) equation of state. The experimental data are also compared with the predictions of the Peng-Robinson (PR) and Soave-Redlich-Kwong (SRK) equations of state using the binary interaction parameter obtained in the MSL correlation. The three equations of state produce comparable qualitative representations of the experimental phase boundaries.
