“…Although 3.5 times lower, the total MEA loss reported in Table 3 (0.081 kg MEA/t CO 2 ) is in the same order of magnitude compared with the CO 2 capture plant results reported by Moser et al (2011a) (0.284 kg MEA/t CO 2 ) in the absence of degradation inhibitors. The model also predicts a lower emission of NH 3 (0.012 kg NH 3 /t CO 2 ) than reported in Moser et al (2011a) where the ammonia emission varied between 0.089 and 0.160 kg NH 3 /t CO 2 .…”

The differences between the model predictions and the MEA loss and ammonia emission observed in pilot plant may be due to the assumptions done in first approach.…”

“…However, Azzi et al (2014) acknowledged that the losses they reported were partially due to plant leakages and to solvent sampling. Maybe the most precise determination of the MEA consumption rate was performed by Moser et al (2011a) for the Niederaussem pilot plant. Indeed, this latest study could close the MEA balance within a measuring uncertainty of only 10%, so that its results can be discussed with confidence.…”

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.

“…Indeed, the total MEA loss equals 0.082 kg MEA/t CO 2 and recent pilot plant results (Moser et al, 2011) report a degradation rate of 0.284 kg MEA/t CO 2 in the absence of degradation inhibitors. This difference may be due to two assumptions done in first-approach, which are to neglect the presence of SO X and NO X contaminants in the flue gas, and to neglect the presence of dissolved metals in the solvent solution as well.…”

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.

“…The consumption of the solvent varies per type of solvent but is for postcombustion typically in the order of 1-2 kg/tonne CO 2 captured. Recent pilot plant test campaigns report solvent consumption rates for MEA at 0.3 kg/tonne captured (Moser et al 2011). Typically, the consumption of MEA is higher compared to its alternatives.…”
