Abstract
Mixing time studies have been carried in a 0.3m diameter and 0.9m tall vessel equipped with three impellers. Conductivity measurement technique has been used for the measurements of mixing time. Effect of the various parameters i.e. tracer density, tracer volume, speed of rotation and impeller combination on mixing time has been studied for two impeller combinations used viz. PTD-PTD-PTD and PTD-PTD-DT. A compartment model (with one fitted parameter, the exchange flow rate QE) with single compartment per agitation stage has been used to predict the conductivity response and the exchange coefficients are calculated from the model parameter. An attempt has been made to explain the experimental results on the basis of the liquid phase axial dispersion coefficient and cell residence time, calculated from the model parameter QEMixing Time Studies, Multiple Impeller Agitated Reactors, Conductivity Measurement Technique, Tracer Density, Tracer Volume, Rotation Speed, Impeller Combination, PTD-PTD-PTD, PTD-PTD-DT, Compartment Model, Exchange Flow Rate, QE, Conductivity Response, Exchange Coefficients, Axial Dispersion Coefficient, Cell Residence Time, Agitation Stages, Mixing Efficiency, Reactor Hydrodynamics, Liquid Phase Mixing, Process Optimization, Industrial Mixing, Fluid Dynamics, Chemical Engineering, Reactor Design
