Fluid phase equilibria for the CO2 + 2,3-dimethylbutane binary system from 291.9 K to 373.1 K

نویسندگان

چکیده

The phase behavior of the CO2 (1) + 2,3-dimethylbutane (2) binary mixture has been experimentally studied between 293 and 373 K. Saturation pressures, ranging from 14.0 to 112.2 bar, were visually measured using a high-pressure cell at carbon dioxide mole fractions 0.20 0.93. 78 experimental points have measured: 67 bubble 11 dew points. Experimental results reveal that vapor-liquid critical locus is continuous curve two pure compounds, meaning system exhibits type I or II in classification scheme Van Konynenburg Scott. data can be very satisfactorily represented by Peng-Robinson equation state with mixing rules embed temperature-dependent interaction parameter.

Volumetric Properties and Fluid Phase Equilibria of Co2 + H2o

The need for accurate modeling of fluid-mineral processes over wide ranges of temperature, pressure and composition highlighted considerable uncertainties of available property data and equations of state, even for the CO2 + H2O binary system. In particular, the solubility, activity, and ionic dissociation equilibrium data for the CO2-rich phase, which are essential for understanding dissolutio...

Solubility of Cis, Cis-Muconic Acid in Various Polar Solvents from 298.15 K to 348.15 K

The present work concerns with an investigation on the solubility of cis,cis-muconic acid dissolution in different polar solvents by characterizing and modeling the dissolution as a function of temperature. Water, ethanol, 2-propanol and acetic acid have been investigated as solvents in the range temperatures from a 298.15 to 348.15 K. Owing to the absence of cis,cis-muconic acid solubility...

Experimental Limits on Complete Positivity from the K-k System

Available data on measured observables allow deriving estimates for some of the phenomenological parameters that characterize the timeevolution and decay of the neutral kaon system based on the hypothesis of complete positivity. The present experimental uncertainties are still too large to permit a full test of complete positivity.

Effect of three-body interactions on the vapor-liquid phase equilibria of binary fluid mixtures.

Gibbs-Duhem Monte Carlo simulations are reported for the vapor-liquid phase coexistence of binary argon+krypton mixtures at different temperatures. The calculations employ accurate two-body potentials in addition to contributions from three-body dispersion interactions resulting from third-order triple-dipole interactions. A comparison is made with experiment that illustrates the role of three-...
