Abstract
AbstractAeration of relatively viscous liquids. The article considers the flooding point and stirrer performance, as well as mass transfer in agitator vessels and bubble columns, in relatively viscous (aqueous glucose and glycerol solutions as well as millet broth) and non‐Newtonian liquids (aqueous CMC and PAA solutions). Numerous experimental results published in the available literature and several obtained by the author provide a basis for these considerations. All the experimental results are presented in the framework of similarity theory. Thus it also proves possible to present the kLa values in sorption characteristics. In order to achieve this aim, a representative viscosity is introduced for non‐Newtonian liquids, both in agitator vessels and in bubble columns. The comprehensive and comparative account reflects the current state of the art. Design data and dimensioning criteria are given for certain systems and working ranges. Comparison between agitator vessels and bubble columns on the basis of the design data derived permits predictions to be made regarding the suitability of various articles of equipment. Some of the results have already been reported [1].
