A MODEL FOR ABATEMENT OF CO2 EMISSIONS BY DE-ABSORPTION WITH MONOETHANOLAMINE
RÉSUMÉ
Due to the adverse effect of CO2 from fossil fuel combustion on the earth's ecosystems, finding the most cost-effective method for CO2 capture is an important area of research. The predominant process for CO2 capture currently employed by industries is chemical absorption in amine solutions. A dynamic model for the de-absorption process was developed with monoethanolamine (MEA) solution. Henry's law was used for modeling the vapor phase equilibrium of the CO2, and fugacity ratios calculated by the Peng Robinson equation of state (EOS) were used for H2 O, MEA, N2, and O2. Chemical reactions between CO2 and MEA were included in the model, along with the enhancement factor for chemical absorption. Liquid and vapor energy balances were developed to calculate the liquid and vapor temperature, respectively. The model results compare favorably with other published results.
