Determination and correlation of vapor-liquid equilibrium data for camphene+(+)-3-carene system
摘要
Abstract
The insulation, stirring and pressure control system of Ellis equilibrium still with double circulator for the vapor and liquid phases was improved, and a set of phase equilibrium experimental device with visual window was established. The vapor-liquid equilibrium data of terpene+(+)-3-decene system at 313.15, 373.15 and 433.15 K were determined. The thermodynamic consistency test was performed on the experimental data by area method and Van Ness test. All data were consistent with Gibbs-Duhenm. Furthermore, the VLE data were correlated by the nonrandom two-liquid (NRTL), Wilson and universal quasichemical (UNIQUAC) activity coefficient models in Aspen plus. The objective function was optimized by the maximum likelihood method and the corresponding binary interaction parameters were returned. The results show that the maximum average relative deviation between calculated values and experimental data of the vapor phase molar composition and equilibrium pressure was 0.0128 and 0.0009, the maximum root mean square deviations are 0.0003 and 0.0012 kPa, and the absolute average deviations of relative volatility are 0.09%, 0.03% and 0.04%, respectively.关键词
