Application of infinite dilution activity coefficients for determining binary equation of state parameters / Christian S. Schacht in Industrial & engineering chemistry research, Vol. 49 N° 16 (Août 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 16 (Août 2010) . - pp. 7646–7653 Titre : Application of infinite dilution activity coefficients for determining binary equation of state parameters Type de document : texte imprimé Auteurs : Christian S. Schacht, Auteur ; Lawien Zubeir, Auteur ; Theo W. de Loos, Auteur Année de publication : 2010 Article en page(s) : pp. 7646–7653 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Binary  Equation Résumé : Infinite dilution activity coefficients can be determined relatively fast from several experimental techniques. Literature values for the infinite dilution activity coefficients are used to determine a binary interaction parameter of the perturbed-chain polar statistical associating fluid theory (PCP-SAFT) equation of state. The model is, subsequently, applied to the full concentration range of binary mixtures, and the results are compared to experimental data from literature. The applicability of the method is demonstrated for examples involving polar, associating, and polymeric components. It is confirmed that the parametrization allows for extrapolations in temperature. In combination with a group-contribution model for the estimation of infinite dilution activity coefficients (e.g., modified UNIFAC(Do)), the equation of state can be used to predict vapor−liquid equilibria of mixtures.

High-pressure phase behavior of the binary systems (propane + diamantane) and (ethane + diamantane) / Wim Poot in Industrial & engineering chemistry research, Vol. 47 n°15 (Août 2008) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 47 n°15 (Août 2008) . - p. 5146–5151 Titre : High-pressure phase behavior of the binary systems (propane + diamantane) and (ethane + diamantane) Type de document : texte imprimé Auteurs : Wim Poot, Auteur ; Theo W. de Loos, Auteur Année de publication : 2008 Article en page(s) : p. 5146–5151 Note générale : Bibliogr. p. 5151 Langues : Anglais (eng) Mots-clés : Vapor-liquid  equilibria;  Solid-fluid  equilibria;  Propane  +  diamantane  system;  Ethane  +  diamantane  system Résumé : (Solid + fluid) and (vapor + liquid) equilibria for the binary systems (propane + diamantane) and (ethane + diamantane) were determined according to the synthetic method in the temperature range 360−510 K and in the pressure ranges 0.3−14 and 0.3−200 MPa, respectively. Also, for both systems the high-temperature branch of the three-phase curve (solid diamantane + liquid + vapor) was determined. In both systems, this curve starts at the second critical endpoint where the three-phase curve intersects the vapor—liquid critical curve and runs to higher temperature with a negative slope dP/dT to the triple point of diamantane. Due to a solid—solid transition of pure diamantane, the three-phase curve (solid diamantane + liquid + vapor) of both systems shows an abrupt change in slope at the point where it intersects the solid—solid transition curve of diamantane. This quadruple point SISIILV is found for (propane + diamantane) at T = 442.64 K and P = 4.110 MPa and for (ethane + diamantane) at T = 445.49 K and P = 9.35 MPa. Some vapor—liquid critical points at low mole fractions of diamantane are reported as well. The coordinates of the second critical endpoint of the (solid diamantane + liquid + vapor) curve are T = 416.28 K and P = 22.81 MPa for (ethane + diamantane) and T = 402.46 K and P = 6.265 MPa for (propane + diamantane).

State - of - the - art of CO2 capture with ionic liquids / Mahinder Ramdin in Industrial & engineering chemistry research, Vol. 51 N° 24 (Juin 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 24 (Juin 2012) . - pp. 8149–8177 Titre : State - of - the - art of CO2 capture with ionic liquids Type de document : texte imprimé Auteurs : Mahinder Ramdin, Auteur ; Theo W. de Loos, Auteur ; Thijs J.H. Vlugt, Auteur Année de publication : 2012 Article en page(s) : pp. 8149–8177 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Ionic  liquids Résumé : Economical and environmental aspects are the main motivation for research on energy efficient processes and the search for environment friendly materials for CO2 capture. Currently, CO2 capture is dominated by amine-based (e.g., monoethanolamine) technologies, which are very energy intensive and less attractive from an environmental point of view due to emissions of the used volatile solvent components. Ionic liquids have been proposed as a promising alternative to the conventional volatile solvents, because of their low volatility and other interesting properties. This remarkable interest has led to a rapid growth of literature on this specific subject. The aim of the present review paper is to provide a detailed overview of the achievements and difficulties that has been encountered in finding a suitable ionic liquid for CO2 capture from flue-gas streams. A major part of this review includes an overview of the experimental data of CO2 solubility, selectivity, and diffusivity in different ionic liquids. The effect of anions, cations, and functional groups on the CO2 solubility, biodegradability, and toxicity of the ionic liquids are highlighted. Recent developments on task-specific ionic liquids and supported ionic liquid membranes are also discussed. Scarcely available results of molecular simulations, which is a valuable tool in designing and evaluating ionic liquids, are also reviewed. The trends highlighted here can be used by solvent designers to navigate through the massive amount of theoretically possible ILs.
