kLa Measurement by Dynamic Sulfite Method in Agitated Vessel

Original language description

The important characteristic of gas-liquid contactors is the intensity of mass transfer which is characterized by the volumetric mass transfer coefficient - kLa. For the kLa measurement various methods exist (i.e. steady state methods, dynamic pressure method, gassing-out method, dynamic start-up method). One of these methods is dynamic sulfite method. 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 non-ideal mixing. The volumetric mass transfer coefficient kLa is given by the ratio of the oxygen and sulfite concentration at any known time.
