Binary Vapor-liquid Equilibria of Carbon Dioxide-light Hydrocarbons at Low Temperature*
light hydrocarbons at low temperatures is of interest in the design of the proper equipment to make such separations. In the previous paper4) of this series, the equilibrium relationships for two binary mixtures of carbon dioxide with ethylene and ethane at 0°C have been described. Those for the ethylene and ethsine binaries with carbon dioxide have been shown to form, minimum-boiling azeotrope...
متن کاملPrediction 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...
متن کاملCapillary Waves at the Liquid-Vapor Interface. Widom-Rowlinson Model at Low Temperature
We have examined in detail the structure and properties of the liquid-vapor interface for the two-dimensional Widom-Rowlinson model in its low-temperature regime. Various simplifying features permit the deduction of several basic results. Included among these are (1) unambiguous definition of capillary wave modes with upper wavelength cutoff proportional to ~ 1 l ’ ~ (el = liquid density); (2) ...
متن کاملVapor-liquid equilibria for methanol + fatty acid methyl ester binary systems near critical temperature of methanol
In biodiesel production processes using supercritical methanol, the phase equilibria for methanol + fatty acid methyl ester systems near the critical temperature of methanol (Tc = 512.6 K) are required as the fundamental data. A flow type method was applied to measure the vapor-liquid equilibria for methanol + fatty acid methyl ester binary systems at 493 – 543 K. The phase behavior was studied...
متن کاملMolecular model for carbon dioxide optimized to vapor-liquid equilibria.
A molecular model for carbon dioxide is presented, and the parameters of the Lennard-Jones sites, the bond length, and the quadrupole moment are optimized to experimental vapor-liquid equilibrium data. The resulting molecular model shows mean unsigned deviations to the experiment over the whole temperature range from triple point to critical point of 0.4% in saturated liquid density, 1.8% in va...
