57 Scaling-up of bubble reactors on basis of laboratory data

František Kaštánek; Jindřich Zahradník; M. Rylek; Jan Kratochvíl

Abstract A simple method is suggested for the modelling of hydrodynamics of reacting gas-liquid systems in large-scale bubble column reactors. Values of liquid-side mass transfer coefficient (kL), interfacial area (a), and gas holdup ratio (e) in a large-scale apparatus can be predicted on the basis of experimental gas holdup data obtained for the reacting system and for an appropriate standard (reference) system in a laboratory-scale bubble reactor. Examples of the modelling are presented for the cases of oxidation of isobutyraldehyde to isobutyric acid and absorption of CO2 into NaOH solution.
