Abstract

Vapor-liquid equilibrium (VLE) data were measured for CO2 with ethyl caproate, ethyl caprylate, and ethyl caprate using a semi-flow type apparatus at 308.2, 318.2 and 328.2 K over the pressure range from 1.6 to 9.2 MPa. In this paper, VLE data are reported. The VLE data were also correlated using the Soave-Redlich-Kwong and the Peng-Robinson equations of state with various mixing rules. It is shown that both equations of state agreed well with the experimental data.
