Resumé

Carbon dioxide absorption by monoethanolamine (MEA) is a very extensively studied process and its modeling represents an open issue in the specialized literature. In the present work, the key parameters necessary to set the absorber model are discussed and evaluated based on rigorous analysis. The experimental data from two different absorption plants size were considered to validate the model. The material and the thermal Peclet number were evaluated for both plants in order to quantify the influence of the axial diffusion/dispersion. The results obtained from the Peclet number evaluation were used to correctly define the number of segments required in the rate-based model. Moreover, the uncertainty in the kinetic parameters associated to the reaction between MEA and CO2 reaction was examined to define a new set of values that minimize the standard error between the experimental and predicted temperature and composition values. The model proposed describes correctly the experimental data and particularly the bulge in the temperature profile, independently on its location. This result is particularly significant when it is required to examine the dynamic behavior of the column or when it is necessary to set an appropriate control system.
