Abstract
Vapor-liquid equilibrium data are reported for the ternary system methyl oleate-squalene-carbon dioxide in the temperature range of 313-343 K and in the pressure range of 11-21 MPa. Experiments were performed in a continuous-type equilibrium apparatus by using a static mixer ensemble to promote the equilibrium between the gas and liquid phases. High selectivity of carbon dioxide towards methyl oleate was obtained. Equilibrium data were correlated using the Soave-Redlich-Kwong equation of state with the Mathias-Klotz- Prausnitz mixing rule. The binary interaction parameters were optimized by minimizing the deviations between the calculated and experimentally determined vapor and liquid phase compositions and distribution coefficients of each substance. A fairly good correlation of the data could be obtained with an average absolute deviation (AAD) of 1.3×10-2.
