Volumetric mass transfer coefficient in viscous liquid in mechanically agitated fermenters. Measurements and Scale-up.
Original language description
Transport characteristic such as volumetric mass transfer coefficients, kLa, is the key parameter in the design of mechanically agitated gas–liquid contactors. For their successful design, values of the key parameter can be estimated using empirical correlations. The goal of this work is to complete a complex study to investigate the behavior of kLa in multiple-impeller vessels in non-coalescent viscous batch. We used the dynamic pressure method (DPM). The experiments were conducted in multiple-impeller vessels of both laboratory and pilot-plant scale, which enabled the scale-up 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 gassing rates. For all impeller combinations, the volumetric mass transfer coefficient was measured in viscous batch. The measured transport characteristic was summarized into correlations. Several literature correlations were judged, using these extensive datasets. In addition to this, new correlation shapes were also established. These correlations can be used to predict transport characteristics in industrial-scale vessels under a wide range of operational conditions.
