Abstract
The study relates to the mass transfer and the bubble size in a non st andard vessel equipped with various dual-impeller combinations. The ef fects of the rotational speed, gas flow rate, impeller type and diamet er are investigated. The volumetric mass transfer coefficient k(L)a an d the bubble size d(bs) were studied. The liquid side mass transfer co efficient k(L) and the volumetric interfacial area a were estimated se parately. A comparison has been made with some existing correlations.
