Abstract
This paper reports a detailed study of the hydrodynamic variables involved in the operation of 6-blade (flat) turbine agitated gas-liquid contractors. New information is presented regarding the characteristic velocity of the dispersed gas bubbles. Generalized correlations for prediction of power consumption of impellers under aeration conditions, gas phase holdup, characteristic velocity, mean residence time of gas bubbles, interfacial area of contact and mean bubble size are proposed in terms of system variables.Keywords
