Abstract
The influence of polymer additives upon the gas‐liquid mass transfer in stirred tanks is examined. While the addition of sodium carboxymethyl‐cellulose brings about a reduction of the overall liquid side mass transport coefficient which is in line with the predictions by earlier works, the reduction ofkLain polyacrylamide solutions of equal viscosity is much stronger. This is explained by the viscoelasticity of the PAA solutions, and an empirical correlation is proposed.Keywords
