A theoretical analysis was developed to predict the apparent viscosity of a non-Newtonian fluid in a rotating packed bed. It is based on laminar liquid film flow on a rotating disk with the assumption of the randomly inclined surfaces in the rotating packed bed. In addition, experiments of deoxygenation were performed in CMC solutions, which are shear-thinning fluids. It is shown that mass transfer coefficients decreased with increasing apparent viscosity, while the centrifugal force still revealed effective in enhancing mass transfer in viscous media. A correlation for mass transfer coefficient was proposed. Compared with a packed column, the influence of mass transfer coefficients by liquid viscosity was less in a rotating packed bed.
