The mechanically stirred internal loop airlift reactors equipped with or without static mixersare devised for intensification of gas-liquid mass transfer rate. The influences of superficial gas velocity,agitation or static mixers on gas hold-up, mixing time, liquid circulating velocity and volumetric masstransfer coefficient have been investigated with tap water andcarboxymethyl cellulose(CMC) aqueous solution. The experimentalresults indicate that mechanical agitation is more efficacious than static mixer in highly viscous mediafor improving mass transfer in airlift reactors. The empirical correlation of volumetric mass transfercoefficient with apparent viscosity, and energy consumption for mechanical agitation and aeration isdeveloped.
