Sensitivity study for the rate-based simulation of the reactive absorption of CO2

The N 2 O analogy in the CO 2 capture context: Literature review and thermodynamic modelling considerations

“…(1) that Henry's constant of CO 2 in water has a direct impact on the equilibrium model, and therefore on the desorption model. Tönnies et al (2011) used the rate-based model in ASPEN plus s to simulate the CO 2 capture process using the benchmark 30 wt% monoethanolamine (MEA) solution with removal rate of 90%-which is the normally targeted operating condition of a large scale plant (which is the case of Boundary Dam). The authors show that if Henry's constant of CO 2 in water is underestimated by 10%, the simulated CO 2 desorbed mass flow decreases 3%.…”

CO2 Capture Technology – from Research to Large Scale Industrial Operation

“…Für eine zuverlässige Modellierung des Prozesses sind genaue Gaslöslich-keitsdaten ebenfalls essentiell, da die Gaslöslichkeit einen großen Einfluss auf die Simulationsergebnisse hat [6]. Obwohl MEA das Standardlösungsmittel für diesen Prozess ist, streuen die Literaturwerte sehr stark.…”

NMR spectroscopic method for studying homogenous liquid phase reaction kinetics in systems used in reactive gas absorption and application to monoethanolamine–water–carbon dioxide

“…For the development and scale-up of reactive absorption processes, accurate physico-chemical models, especially for the description of reaction equilibria and kinetics in the liquid phase, are essential [6]. Reaction kinetic data in such systems are in most cases obtained from measurements, in which both mass transfer and reaction kinetics play a role.…”
