Hydrodynamic and mass transfer studies with highly viscous pseudoplastic solutions of CMC were carried out in a 14 cm (i.d.) bubble column operated cocurrently under bubbly and slug flow conditions. Specific interfacial areas were measured by the sulfite oxidation technique. The volumetric mass transfer coefficients determined by the stationary physical method in the CMC solution containing sodium sulfate follow a k /SUB L/ a correlation proposed for pure CMC solutions. By combining the results it was possible to evaluate the liquid-side mass transfer coefficients.
