Prediction of power consumption and mass transfer in mechanically agitated fermenters, physical interpretation of experimental data.
Original language description
In the industrial fermentation processes, most of the liquids are non-coalescent batches and few of them are coalescent. However, due to the limitations of most measurement methods, there is a lack of reliable data for predicting volumetric mass transfercoefficients (kLa) for non-coalescent batches under high dissipated energies. Our goal is to propose accurate kLa and power input (P) correlations for these conditions. Thus kLa was measured with the highly precise dynamic pressure method. Measurementswere conducted in a two phase multiple-impeller fermenter with a non-coalescent and coalescent batch under a wide range of conditions. The classic correlation for kLa is based on P and superficial gas velocity, but we found that when impeller tip speed is switched with P it improved the closeness of the correlation for non-coalescent batches. The data aggregated from different impellers showed that the impeller power number is a reliable predictor of kLa for most impeller types. We confi
