Abstract This article presents the influences of suspenson concentration, gas volume in liquid and power consumption on gas liquid mass transfer characteristic for low viscosity system using a new type axial impeller (K 4), 45°pitched blade disk turbine (pumping down and up) and disk turbine (DT) respectively in three phase stirred vessels, It is concluded that: K 1a∝(P g/V) k ; and if the apparent viscosity of suspension changes little due to the suspension concentration, the presence of solid makes the volumetric mass transfer coefficient K 1a increase, and K 1a is enhanced with the increasing of gas volume, Because the new type axial impeller (K 4) produces higher axial dispersion and mixing, the K 1a value keeps higher in same power consumption.
