Multiphase Stirred Tank Bioreactors – New Geometrical Concepts and Scale‐up Approaches

Abstract: Mainly with respect to biotechnological cases, current developments in the field of impeller geometries and findings for multistage configurations with a specific view on aerated stirred tanks are reviewed. Although often the first choice, in the given case the 6‐straight blade disc turbine is usually not the best option. Furthermore, quantities usable for scale‐up, specifically applicable in this field are discussed. Only quantities taking local conditions into account appear to be able to actually compare di… Show more

“…One of the biggest issues that has arisen from that situation is the question of shear damage and how it might change on scale-up. In 2019, Matthias and co-workers published in Chemie Ingenieur Technik [2] a very interesting paper of which a significant proportion was on this topic. Since my first biochemical engineering mixing publication in 1979 related to this issue [3] and it has recurred many times since then, I thought it would be interesting to follow a similar theme here.…”

“…Derzeitige Forschungsschwerpunkte erzielten erfreuliche Fortschritte beispielsweise bei der Beschreibung des Stofftransports zwischen der Gas-und der Flüssigphase. Exemplarisch seien hier [10][11][12][13] erwähnt. Werden diese neuen Erkenntnisse in Form von Korrelationen beschrieben, wäre eine Anwendung in einem solchen Modell ebenfalls möglich und könnte die Zuverlässigkeit der Beschreibung der Sensitivität des Wechselspiels zwischen Fluiddynamik und Reaktion erhöhen.…”
