The kinetic model for oxidative degradation of MEA has been adapted from the work by Braakhuis et al. . The model is developed using experimental data produced by Vevelstad et al. , who used an agitated bubble reactor at temperatures between 55 °C and 75 °C and gas phase oxygen concentrations between 6 vol-% and 98 vol-% . Liquid phase mass transfer resistances for O2 were expected to be present in the agitated bubble reactor, especially at higher temperatures. This would reduce the availability of dissolved O2 and limit the overall degradation rate. Therefore, mass transfer resistances have been approximated and accounted for during the development of the degradation model .
