摘要
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.
