Mathematical Model for Monitoring Gas-Liquid Reactors by Means of Continuous Flow Analysis

A Global Mathematical Model, which predicts the observed signal in a detector when Continuous Flow Analysis (CFA) is used for the monitoring of ozone gas-liquid reactors, has been proposed. This model combines the description of mass transfer and kinetic processes in the reactor (based on Surface Renewal and Film Layer theories) with dispersion in the manifold of the CFA. To validate the Global Model, the reaction between ozone and a dye (blue indigo trisulfonate) in a semi-batch gas-liquid reactor monitored by CFA is investigated.
