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