Three phase fluidized beds are widely employed in process industries. The ongoing examination is conducted to detect the improvement in coefficients of ionic mass transfer in the presence of an hourglass promoter element in a three phase fluidized bed. Data on coefficient of mass transfer is obtained by employing a diffusion-controlled electrode reaction—reduction of ferricyanide ion. Coefficients of mass transfer are estimated using the measured data on limiting current data for several combinations of flow rates of liquid and gas, pitch, bed porosity, characteristic length, promoter rod diameter and particle diameter. Correlations are also developed for coefficient of mass transfer by regression analysis with the use of proper dimensional groups relating geometrical parameters and flow variables.
