Abstract
This paper proposes a new approach of applying an optimization technique to simultaneously determine a physical liquid—film mass transfer coefficient (K^o^~L~) and effective interfacial area (a~v~) from a pilot plant data. The mass transfer mechanism of the CO~2~‐NaOH system was modeled using the two‐film theory to represent the behaviors of packed absorbers. The model presents an overall absorption rate (R~v~) as a function of K^o^~L~ and a~v~. The optimization algorithm used in this study follows a modified Levenberg‐Marquardt method with a trust region approach. The R~v~ predictions from the model are in good agreement with the experimental data, with an average error of 6.5%.
