Dependence of Holdup on Height in a Pulsed Plate Column Based on Binary Liquid-Liquid Equilibrium Data
Holdup has been measured at various frequencies, amplitudes, continuous and dispersed phase flow rates for binary systems in a pulsed plate column capable of providing samples at various heights.

description | Holdup has been measured at various frequencies, amplitudes, continuous and dispersed phase flow rates for binary systems in a pulsed plate column capable of providing samples at various heights. The binary systems have been so selected as to cover a wide spectrum of interfacial tensions. Dispersed phase holdup was found to increase with height in a logarithmic fashion at conditions away from the flooding point and to become almost invariant with height near flooding conditions. The interfacial tension of the binary system has a large effect on the dispersed phase holdup. In systems having low interfacial tension, a small increase in any of the parameters can increase the holdup significantly and lead to flooding. In systems having high interfacial tension, on the other hand, variations in system parameters do not affect system performance significantly.
La rétention a été mesurée à des fréquences, amplitudes et débits des phases continue et dispersée variés, pour des systèmes binaires dans une colonne à plateaux pulsée capable de fournir des échantillons à différentes hauteurs. Les systèmes binaires ont été sélectionnés de façon à couvrir une vaste gamme de tensions interfaciales. On a trouvé que la rétention de la phase dispersée augmentait avec la hauteur selon un mode logarithmique à des conditions éloignées du point d'engorgement et devenait invariante avec la hauteur près des conditions d'engorgement. La tension interfaciale du système binaire a un effet important sur la rétention de la phase dispersée. Dans les systèmes ayant une faible tension interfaciale, une petite augmentation de l'un des paramètres peut accroître significativement la rétention et mener à l'engorgement. Par ailleurs, dans les systèmes à tension interfaciale élevée, les variations des paramètres du système n'influent pas de manière significative sur la performance. |
