Bubble size and mass transfer coefficients in dual‐impeller agitated reactors

Abstract

Abstract The study relates to the mass transfer and the bubble size in a non standard vessel equipped with various dual‐impeller combinations. The effects of the rotational speed, gas flow rate, impeller type and diameter are investigated. The volumetric mass transfer coefficient k L a and the bubble size d bs were studied. The liquid side mass transfer coefficient k L and the volumetric interfacial area a were estimated separately. A comparison has been made with some existing correlations.
