Propriétés thermodynamiques de systèmes contenant des gaz acides. Étude bibliographique

Abstract: Résumé -Des besoins de plus en plus importants se font sentir quant à la connaissance du comportement de mélanges contenant des gaz acides (CO 2 et H 2 S) avec des hydrocarbures et/ou de l'eau. Ces besoins sont actuellement bien identifiés dans le domaine de l'injection de gaz acides pour la production améliorée d'hydrocarbures et/ou pour se conformer aux contraintes environnementales (gisements poubelles). En particulier, la description du comportement des mélanges fluides (gaz injecté + hydrocarbures en plac… Show more

“…The current knowledge of thermodynamics of simple systems under high pressure (H 2 O + H 2 S or H 2 O + CO 2 ) is discussed in the recent literature (Ji and Zhu, 2010;Koschel et al, 2006Koschel et al, , 2007Dubessy et al, 2005;de Hemptinne and Béhar, 2000). Most of these models are based on equations of state (EOS) for the gas phase and Henry's law, or an activity model for the aqueous phase.…”

“…A large amount of solubility data for CO 2 and H 2 S over a large range of temperatures (up to 380 • C) and pressures (35 MPa) has been published, mainly relating to the solubility of pure gases in water and saline water (Burgess and Germann, 1969;Kuranov et al, 1996;Dhima et al, 1999;Koschel et al, 2006Koschel et al, , 2007. Conversely, data on the solubility on CO 2 + H 2 S mixtures in water are scarce and only available at low pressure (<6 MPa) for a nonaqueous low-density phase (see review of de Hemptinne and Béhar, 2000). Therefore, there is essentially no reliable information on the solubility of gas mixtures in pure and saline solutions at high temperatures.…”

“…Considering that the structure of the mixed c-C5H10 + CO2 hydrates, is a type II cubic clathrate structure (De Hemptinne and Behar, 2000;Sloan Jr et al, 2007), and assuming that the c-C5H10 molecules occupy 100 % of the large cavities (Zhang et al, 2004), the formation of the mixed hydrates can be written by the equation (Eq.2):…”
