Hydrodynamics and masstransfer of triplet loop biological fluidized bed reactors were studied in terms of gas holdup, liquid circulation velocity and volumetricmasstransfercoefficient.
The volumetricmass-transfercoefficient in packing increases with gas flow rate and rotating speed raises. Liquid flow rate and concentration of SO2 in inlet gas influences less on it.
