Abstract

Isothermal-vapor-liquid equilibrium data of the rapeseed oil-carbon dioxide system were measured with a vapor-recirculation apparatus at 313.15, 333.15, 353.15, and 373.15 K at pressures between 10 and 85 MPa. The solubilities of rapeseed oil in carbon dioxide were compared with solubility data of other vegetable oils from the literature. A lattice model equation of state (EOS) is used to describe the rapeseed oil-carbon dioxide system. The lattice EOS was improved by introducing a more accurate EOS for carbon dioxide (Bender EOS) into the model. With the Kumar-Bender model and a tree-binary-parameter, composition- and density-dependent combining rule proposed by Wilczek-Vera and Vera, a quantitative description of phase equilibrium is obtained. The temperature dependence of the binary parameters has been evaluated for interpolation or extrapolation purposes.

Solubility of small-chain carboxylic acids in supercritical carbon dioxide

Journal Article Sparks, Darrell L. ; Estevez, L. Antonio ; Hernandez, Rafael ; ... - Journal of Chemical and Engineering Data

The solubility of heptanoic acid and octanoic acid in supercritical carbon dioxide has been determined at temperatures of (313.15, 323.15, and 333.15) K over a pressure range of (8.5 to 30.0) MPa, depending upon the solute. The solubility of heptanoic acid ranged from a solute concentration of (0.08 ± 0.03) kg • m ^-3 (T = 323.15 K, p = 8.5 MPa) to (147 ± 0.2) kg • m ^-3 (T = 323.15 K, p = 20.0 MPa). The lowest octanoic acid solubility obtained was a solute concentration of (0.40 ± 0.1) kg • m ^-3 (T = 333.15 K,more »« less

Phase equilibria from PVT measurements for carbon dioxide, water, and n-decane

Thesis/Dissertation Okafor, M N

Phase equilibrium properties for the carbon dioxide - water - n-decane system were determined from pressure-temperature-volume (PVT) measurements. PVT properties were also obtained for pure carbon dioxide and water, and the binary mixtures of carbon dioxide - water and carbon dioxide - n-decane. The experiments were conducted at temperatures of 313.17, 353.15 and 393.15 Kelvin, and at pressures from 37 to 416 bar. Measurements for the mixtures were terminated when complete miscibility was observed. The Perturbed-Hard-Chain (PHC) equation of state developed by Gmehling et al (1979) was chosen to correlate the measured data because of its ability to handle themore »« less
PHASE BEHAVIOR OF LIGHT GASES IN HYDROGEN AND AQUEOUS SOLVENTS

Technical Report GASEM, KHALED A.M. ; ROBINSON, JR, ROBERT L

Under previous support from the US Department of Energy, an experimental facility has been established and operated to measure valuable vapor-liquid equilibrium data for systems of interest in the production and processing of coal fluids. To facilitate the development and testing of models for prediction of the phase behavior for such systems, we have acquired substantial amounts of data on the equilibrium phase compositions for binary mixtures of heavy hydrocarbon solvents with a variety of supercritical solutes, including hydrogen, methane, ethane, carbon monoxide, and carbon dioxide. The present project focuses on measuring the phase behavior of light gases and watermore »« less
