Notizen:
A bubble column absorber was used to investigate kinetics of the reaction between carbon dioxide and aqueous solutions of diisopropanolamine (DIPA), by means of gas absorption experiments. These were conducted in the temperature range of 20 to 40°C, with DIPA concentrations from 5 to 500 mol/m3, and CO2 partial pressures between 5 and 101 kPa. A model based on the Danckwerts' surface reneval theory was used to analyze the experimental results and to determine the rate constant. The obtained data support the assumption of a second-order overall reaction, with the rate constants being well correlated by the Arrhenius equation: \documentclass{article}\pagestyle{empty}\begin{document}$$ k_2 = 1.112 \times 10^{10} \exp \left({ - {{4848} \mathord{\left/ {\vphantom {{4848} T}} \right. \kern-\nulldelimiterspace} T}} \right).$$\end{document}
