Abstract Summary (Max 250 words)
Gas dispersion into the liquid phase by using mechanically agitated reactors has been used widely in chemical, biochemical, and pharmaceutical industries. Accurate estimation of power consumption in the presence of gas as well as determination of gas-liquid mass transfer is essential parameter for reactor design. There are several investigations carried out with single radial turbine impeller and the correlation has been proposed [1]. Nonetheless, power dissipation and mass transfer have been studied with a limited range of configuration, and the correlation has been proposed based on the results from small laboratory to pilot scale vessel. In this study, the power consumption and volumetric gas transfer coefficient of two stages and three stages 6-blade Disk Turbines were examined from vessel size of 310 mm and 600 mm. The estimated correlation was proposed and compared to that data obtained from commercial scale vessels with inner diameter of 1500 mm.
