Abstraet

-Wnamlc oxygen transfer expenments in columns are modelled usmg an unsteady state, two-phase dispersion model for the column, and a second-order lag relation for the eIectrode The model IS solved for the first moment of the step response curve, whu31 can be used to calculate kra when the other model parameters are known The vah&ty of the method IS demonstrated usmg srmulated data obtamed by numerIcally mtegratmg the model equations The accuracy of the esttmated kLa as a function of measurement location and transfer rate IS consIdered MTROMJCTION Column or tubular contactors and reactors requue relatively complex models to descnbe the vanatlon of component concentrations wtth axial distance It 1s generally accepted that
