    KLa measurement by Dynamic Sulfite Method in agitated vessel.

  • Original language description

    For the kLa measurement dynamic sulfitemethod has been used. The method is based on simultaneous monitoring of dissolved oxygen and sulfite ions concentrations after an injection of sulfite solution (or other oxygen consuming species)to the batch initially saturated with aerating gas. The concentration of the sulfite oxidized in an analyzed sample of liquid determines the initial oxygen concentration corrected to nonideal mixing. The volumetric mass transfer coefficient kLa is given by the ratio of theoxygen and sulfite concentration at any known time. The main goal of this contribution is to verify the Dynamic Sulfite Method, as presented by Havelka et al. (1997), in an mechanically agitated vessel for further implementation of this method in an apparatus with an ejector-type gas distributor.
