Abstract

"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 the complexity of the molecular interactions in the mixtures. Binary interaction parameters were regressed for the carbon dioxide - water and carbon dioxide - n-decane mixtures while those of water - n-decane were obtained from ternary data.

A fiber-optic scope was used to observe the number of phases present and qualitatively measure the equilibrium liquid phase volumes. The measured data were then compared to predictions from the model. Ternary diagrams are presented showing predicted coexisting equilibrium phases for the three isotherms and several pressures"-- Abstract, p. ii
