Abstract

The study was performed in a gas-liquid stirred reactor. The knowledge of flow residence time distribution inside the reactor, allows the prediction of its behavior. This information can be obtained by the application of the stimulus-response experimental method. This is the main objective of this study. So in order to characterize the flow patterns though the stirred reactor, it was necessary to perform a tracer test. This test for the determination of the residence time distribution with the use of sodium chloride as a tracer was carried out. Eq f(q) curves at different gas flow, liquid flow and agitation speed were obtained. The minimum agitation speed, which guarantees good gas dispersion into the liquid phase, was determined; the value obtained was 420 r/min . The model that adequately represents the flow pattern of the liquid phase was the one of well mixed reactor. The flow pattern of the liquid phase into the reactor was adequately represented by the well mixed reactor model. Moreover, the absence of dead zones and shortcircuiting starting from the analysis of the fundamental parameters of the applied hydrodynamic pattern was verified. These parameters characterize the mean residence time distribution for each experimental condition. They are the theoretical and experimental mean time of residence and the variance that indicates the width of the distribution. Finally model proposed by Cholette-Cloutier to corroborate the flow pattern proposed was used.
