“…These values are identical to those obtained when not considering degradation reactions since the concentrations of degradation products and the degradation rates are too weak to have any significant influence on the solvent properties, and thus on the process performances. Moreover, these values are in agreement with the experimental value (3.7 GJ/t CO 2 ) reported from the pilot plant campaign under similar conditions by Knudsen et al (2011). Table 3 lists the formation rates of degradation products as well as the MEA degradation rate in the absorber and the stripper.…”

Monoethanolamine thermal and oxidative degradation Process modeling Plant design Integrated experimental and modeling study a b s t r a c tThe CO 2 post-combustion capture with amine solvents is modeled as a complex system interconnecting process energy consumption and solvent degradation and emission. Based on own experimental data, monoethanolamine degradation is included into a CO 2 capture process model. The influence of operating conditions on solvent loss is validated with pilot plant data from literature. Predicted solvent consumption rates are in better agreement with plant data than any previous work, and pathways are discussed to further refine the model. Oxidative degradation in the absorber is the largest cause of solvent loss while thermal degradation does not appear as a major concern. Using a single model, the process exergy requirement decreases by 10.8% and the solvent loss by 11.1% compared to our base case. As a result, this model provides a practical tool to simultaneously minimize the process energy requirement and the solvent consumption in post-combustion CO 2 capture plants with amine solvents.

Solvent degradation may be a major drawback for the large-scale implementation of post-combustion CO 2 capture due to amine consumption and emission of degradation products. However, its influence on the process operations has rarely been studied. In the present work, a kinetics model describing solvent oxidative and thermal degradation has been developed based on own experimental results for the benchmark solvent, i.e. 30 wt% monoethanolamine (MEA) in water. This model has been included into a global Aspen Plus model of the CO 2 capture process. The selected process modelling approaches are described in the present work. Using the resulting simulation model, optimal operating conditions can be identified to minimize both the energy requirement and the solvent degradation in the process. This kind of process model assessing solvent degradation may contribute to the design of large-scale CO 2 capture plants to consider not only the process energy penalty, but also its environmental penalty. Indeed, both aspects are relevant for the large-scale deployment of the CO 2 capture technology.

“…It is widely admitted that this process is the reference for CO 2 capture on flue gases [3]. Within the CASTOR and CESAR FP7 European projects, this process has been demonstrated at pilot plant scale on real power plant flue gas [4][5][6] and some companies are able to commercialize such a process with already some large scale references existing in the food industry [7,8]. Figure 1 shows a typical process flow diagram for a first generation process such as the reference MEA 30 wt% process.…”
