Volumetric mass transfer coefficient in coalescent batch in mechanically agitated fermenters
Original language description
Volumetric mass transfer coefficient (kLa), is the critical transport characteristic in the design of mechanically agitated contactors. 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 non-coalescent viscous batch in mechanically agitated contactors were described and verified. Now, we aim at the description of one universal correlation that would be viable for mechanically agitated contactors in coalescent batch. The experiments were performed in multiple-impeller vessels in a laboratory and pilot-plant scale, which allowed extension studies. Several impeller types with different diameters and their combinations on a common shaft were used in the vessel, under various impeller tip speeds and gas rates. 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.
