Abstract
AbstractIn the design of mechanically agitated fermenters, the volumetric mass transfer coefficient kLa often becomes the key parameter. In case of viscous liquids, kLa prediction based on literature correlations suffers from a wide distribution. The aim is to provide reliable kLa correlations based on a large experimental data set obtained using the dynamic pressure method, the physical correctness of which was verified earlier. Multiple‐impeller fermenters of two scales were used. The impeller tip speed, rather than the power input, revealed to be the proper term for prediction of kLa. When the impeller power number is used, kLa values for various impeller types can be predicted by a common correlation which, based on a wide range of operational conditions, can be applied in the design.
