“…The figure shows that the temperature of the solvent has a significant effect on the saturation in the upper parts of the column (>4 m), while it has no effect on the lower parts where the contact of the gas with the cold solvent happens. These findings are consistent with those reported by Mertens et al, 26 Imle et al, 24 and Fulk and Rochelle. 38 Figure 9 shows the amine loss for different saturation ratios, as obtained from Figure 8.…”

“…Various gas absorption experiments have been reported at the laboratory and pilot scales on the effects of several parameters on amine emissions. These studies showed that the amine emissions are increased by increasing the primary particle or droplet concentrations. ,,− Khakharia et al , demonstrated amine emissions due to vapor and particulate matter (PM). They added sulfuric acid and soot to the flue gas stream and observed an increase in the amount of amine emission from 45 to 600–1100 , suggesting the formation of particulate phase amine through heterogeneous nucleation.…”

The current work was dedicated to developing a novel model based on the mass transfer theory in combination with classical nucleation theory in order to predict the amount of solvent loss in the amine absorption columns. The work was adopted to consider the physical mechanisms leading to amine loss, including mass transfer, aerosol formation, and evaporation of the amine. Aspen Plus simulator and MATLAB software were integrated to make such simulations possible through a round−trip interaction. The model predictions for the temperature and concentration of different components were compared with the literature experimental data, and a fair agreement was seen. Then, the effects of some parameters such as the inlet stream temperature, particle concentration, and diameter on the amine loss were investigated. The results of this study may help engineers and practitioners properly design the amine absorption columns to reduce amine consumption.

The amine-based post combustion carbon capture process is one of the most advanced and preferred technologies to reduce CO2 emissions from point sources like power plants. The emissions of amine from capture plants is one of the biggest challenges faced by this technology. These emissions typically occur by means of aerosol/mist formation. To develop effective countermeasures, it is crucial to understand the dynamic behavior of aerosols within the column, which is currently not well understood. This manuscript presents the results from a study aiming to understand the mechanism of aerosol growth and its behavior along the absorber column in terms of particles number concentration, particle size distribution, and amine emissions. For that, a series of experiments were performed in TNO's bench scale CO2 capture plant using 30 wt% monoethnolamine (MEA) as solvent. For a SO3 and CO2 concentrations of 5.25ppm and 12.5 vol.% in the flue gas, MEA emissions at the top exit of the column were recorded as 1051mg/Nm 3 (with vapour emissions of 381mg/Nm 3 ). In the absence of SO3 in the flue gas, inlet particle concentration was 2.71 x 10 7 /cm 3 and resulting MEA emissions reduced by 63.5% to 383mg/Nm 3 . From the bottom of the column until the point of maximum temperature, the MEA content in the vapour phase was consistent with the volatility of the solvent. After this point it drastically increases to 1051 mg/Nm 3 . Both the number of particles and the total particle mass has lowered from the bottom to the top of the column. For the benchmark test, inlet and outlet total particle concentration were found to be 6.24x10 7 /cm 3 and 2.3x10 7 /cm 3 respectively, while total particle mass is 2.22mg/m 3 at inlet and 1.32mg/m 3 at outlet. Particles with a dimeter below 0.006µm contribute the most to total particle concentration both at the inlet (50%) and outlet (32%), while particles with diameter of 0.087µm contributes the most to the total particle mass at inlet (47%) and outlet (55%). The measured total mass of particles was in the order of magnitude of 1mg/m 3 . This is much lower than the expected aerosol mass emissions, in the order of magnitude of 1 g/Nm 3 based on FTIR emissions. No particles larger than 0.147µm were recorded, which might explain the low total mass recorded. The cause for this is still under investigation, but it suggests that the sampling procedure may induce systematic errors to the measurements. Nonetheless, the observations from this study have given further insight into the aerosol dynamics in the absorber column and corresponding emissions.
