摘要：

A comprehensive experimental study of the volumetric transfer coefficient kLa with Newtonian and non-Newtonian fluids in bubble columns using CO2 as gas phase is the objective of this work. The evaluation of the hydrodynamic characteristics of the bubble columns and delineated the different hydrodynamic regimes considering column geometry, gas flow, liquid height and type of fluid (Newtonian and non-Newtonian) suggest a general applicability of the proposed model. An explanation about of the kLa values in non-Newtonian fluid is offered take into account shear rate, column geometry, viscosity and results reported in the literature previously.
