Modelling and Evaluating Carbamate Polymerization of Monoethanolamine in Post-Combustion Carbon Capture

Abstract

In this work, experimental data on carbamate polymerization of aqueous solutions of monoethanolamine (MEA) has been collected and analyzed. Three degradation models were developed describing thermal degradation of MEA in aqueous solutions to investigate the importance of taking into account MEA consumption when describing the experimental data. The models were fitted to literature data. It was found that with the same number of parameters, a better fit was obtained when considering MEA consumption. All the models showed increased deviations for longer experiments and at higher temperatures, indicating that the high concentration of degradation compounds might influence the degradation rate.
