Abstract
The existing rate-based modeling of monoethanolamine (MEA) solvent for CO(2)capturing has been improved using different kinetic models. Different models obtained from a combination of 15 kinetic models and 4 mass transfer correlations have been applied. The results show that the mass transfer correlation is instrumental for a reliable rate-based model. The resulting framework predicts the temperature and composition profiles at both liquid and gas phases with good accuracy. Overall, this allowed for improved prediction of (i) the CO(2)capture performance, (ii) the CO(2)partial pressure in output gas, and (iii) the temperature and CO(2)composition profiles in the liquid.
