Prediction of kLa is nowadays mostly based on literature correlations. Our aim is to establish suitable kLa correlations for different types of devices that would be based on the experimental data set. In our previous work, the correlation for kLa prediction in coalescent batch were described only for Rushton turbines (Petříček et al., 2019). Now, we aim at the description of one universal correlation that would be viable for mechanically agitated contactors in coalescent batch for several impeller types with different diameters and their combinations on a common shaft. The measured transport characteristics were summarized into correlations. This correlation shape can be used to predict transport characteristics in industrial-scale vessels under a wide range of operational conditions.
