Characterisation of micromixing efficiency by the iodide-iodate reaction system. Part I: experimental procedure

This paper describes in a very practicable way the operating conditions of the iodide-iodate reaction system used to quantify micromixing phenomena in chemical reactors and mixers. Several operating procedures are given for b atch and continuous mixers. Recommendations to adapt these procedures to an y specific mixers and complete analysis procedures are also provided. Final ly, a simple micromixing model is used to calculate micromixing time t(m). It is checked that t(m) is non-dependent on the reactant concentrations at constant hydrodynamic conditions. In a second following paper (Part II), th e reactions kinetics, essential for a knowledge of micromixing time t(m), a re presented. (C) 2000 Elsevier Science Ltd. All rights reserved.
