Abstract:
Mass transfer and axial dispersion coefficients for continues phase were calculated by axial mixing model for continues phase and forward mixing model for dispersed phase simultaneously. Experimental data was achieved in pulsed sieve plate column with 22 cm diameter. Toluene –water-acetone and Butanol-Succinic acid- water were used in this experiment. In these systems continues phase is water and mass transfer takes place from continues phase to dispersed phase. Experimental data involves drop size distributions and operating conditions andconcentration in both phases.For calculating overall mass transfer coefficient for drops the handlos and Baron Model was used. The axial dispersion coefficient was appeared in column model. Comparing experimental concentration profile with predicted concentration from column model these parameter could be optimized. For optimization these coefficients the Genetic Algorithm was used. Results were compared with those were calculated by NAG. At the end the effect of pulse velocity on these coefficients were shown.
