Abstract
Following properties of short bubble columns employing CMC solutions (1.0, 1.4 and 2.0%) and perforated plates (0.5, 1.0 and 3.0 mm hole diameters) were determined: relative mean gas hold up, EG , bubble size distribution, Sauter bubble diameter, ds , and the specific geometrical bubble surface areas, a′ and a″ due to the “intermediate to large bubbles.” The a″ values were compared with the corresponding volumetric mass transfer coefficients, kLa's and the mass transfer coefficients, kL , were estimated. The properties of these systems were investigated as function of the superficial gas velocity, WSG , CMC concentration and aerator type.Keywords
