Experimental investigation of gas-liquid mass transfer of ozone in water, in
bubble column with two-fluid nozzle gas distributor (BKDM), under different
operating conditions, are presented in this work. The main objective was to
determine the ozone volumetric mass transfer coefficient, kL a, in calm
uniform section of the column, under different values of gas and liquid flow
rates. Obtained values of these coefficients were compared with the values in
countercurrent bubble column. The critical liquid flowrate, when gas hold up
reaches its maximum, was experimentally determined. It was shown that the
maximum value of the ozone volumetric mass transfer coefficient is obtained
just when liquid flowrate is at its critical value.
Determination of fluid dynamic parameters through imports of CFD images validated in experiments for the MCNPX code.
