Thermodynamic Consideration of Binary Vapor Liquid Equilibria

Determination of Binary Vapor Liquid Equilibria (vle) of Reactive Systems

The simulation of reactive distillation processes requires binary phase equilibrium data and information about the reaction kinetics and equilibrium. The phase equilibrium data for the binary reacting sub-systems are difficult to measure experimentally since the products of reaction affect the binary equilibrium as soon as they are formed. A novel apparatus has been constructed to measure these...

Prediction of Vapor-Liquid Equilibria Using CEOS /GE Models

The present study investigates the use of different GE mixing rules in cubic equations of state for prediction of phase behavior of multicomponent hydrocarbon systems. To predict VLE data in multicomponent symmetric and asymmetric mixtures such as systems that contain light gases (nitrogen, carbon dioxide, etc.) and heavy hydrocarbons, the SRK equation of state has been combined with excess Gib...

Prediction of Liquid-Liquid Equilibria of Binary Systems Containing Alcohols Using EoS-GE Models

Surface Tension, Large Scale Thermodynamic Data Generation and Vapor-Liquid Equilibria of Real Compounds

The surface tension of oxygen and nitrogen was calculated using molecular dynamics simulation. Due to the inhomogeneity of the system, the long range correction approach of Janeček [1] was used. The results regarding the temperature dependence of the surface tension were compared to simulation data by Neyt et al. [2] and experimental data. Because of simpler statistical analogs of certain therm...

Measurement and Modeling of High Pressure Vapor-liquid Equilibria of Co2 + Alcohol Binary Systems

A new apparatus based on a static-analytic method was developed in this work to perform high-pressure vapor-liquid equilibria measurements up to 68 MPa and 373 K. In order to validate this new apparatus, vapor-liquid equilibria of the binary system CO2 + ethanol was measured at temperatures of 313, 323 and 338 K and pressures from 1.2 to 11 MPa. Results were compared with data from the literatu...
