| dc.description.abstract | Experiments performed at low agitation speeds, using the high interfacial tension toluene (dispersed)-water (continuous) system, in a pilot plant Kühni column, show that coalescence events are generally present and cannot be neglected in column-type liquid-liquid contactors, especially when the goal is the accurate modelling of the transient processes for control purposes. In this work, the features of this behaviour and the applicability to this situation of a new, fast and precise, recently developed algorithm, 1 that describes the dynamic behaviour of an agitated column, is illustrated. Experiments were performed at low agitation speeds, using the above high interfacial tension system. The simulations show reasonably good agreement with the experimental results and provide insight on the underlying behaviour mechanisms and important guidelines for the accurate modelling of the dynamics of the column. | eng |
