Phase equilibria in very dilute mixtures of water and halogenated hydrocarbons / Brahim Khalfaoui 

Public ISBD Titre : Phase equilibria in very dilute mixtures of water and halogenated hydrocarbons Type de document : texte imprimé Auteurs : Brahim Khalfaoui, Auteur ; D. M. T. Newsham, Directeur de thèse Editeur : Manchester : [s.n.] Année de publication : 1992 Importance : 151 f. Présentation : ill. Format : 30 cm. Note générale : Phd Thesis : Chemical engineering : University of Manchester: 1992 Annexe f. 152 - 206 . Bibliogr. f. 207 - 216 Langues : Anglais (eng) Mots-clés : Halogenated  hydrocarbon Water  systems Gas-liquid  chromatographic Isopiestic  apparatus UNIFAC  model Infinite  dilution  activity  coefficients Index. décimale : D001592 Résumé : The present work is divided into two parts. Firstly, the experimental determination of the activity coefficients at infinite dilution for a number of halogenated hydrocarbon/water systems in the temperature range 285.15 K to 323.15 K hasneen made. Two different techniques havebeen used for their study, a gas-liquid chromatographic technique for water-rich mixtures and an isopiestic apparatus for organic-rich mixtures. The second part of this work is to estimate new or updated group interaction parameters for the UNIFAC model and two of its modifications, the effective UNIFAC and the effective UNIFAC with modified Staverman-Guggenhem combinatorial, using the experimental data. The updated parameters have been used to predict infinite dilution activity coefficients for a range of halogenated hydrocarbon/water mixtures not measured in this work. A comparison of experimental and calculated activity coefficients has proved encouraging.
