Carbon dioxide capture and storage (CCS) technologies have been proposed as a promising alternative to reduce CO 2 emissions from fossil fuel power plants with post-combustion capture. Absorption by aqueous amine-solutions is considered the most mature and industrially developed technology for post-combustion capture. One of the most signifi cant issues hindering a large deployment of this technology is potential amine degradation. Amines degrade in presence of O 2 , CO 2 , NO x , SO 2 , and heat resulting in solvent loss, equipment corrosion and generation of volatile degradation compounds. Two types of degradation have been identifi ed in the literature, namely oxidative and thermal degradation. A review of the amine-based solvents, its main degradation products, the apparatus and analytical methods most widely used, as well as the mechanism proposed and kinetic studies are presented and discussed here. Moreover, amines emissions from CO 2 capture units can react in the atmosphere via photo-oxidation and also via NO X reactions to give nitrosamines and nitramines, which are potentially harmful to the human health and the environment. A discussion of the recent works on atmospheric degradation of amine solvents is also included in this review.

“…This significant amount of amine emission led to an increase in the operating costs. Furthermore, the exhausted amine reacted with Nox in the flue gas to form nitrosamines (Dave et al, 2010;Fine et al, 2013). Kamijo et al (2013) compared amine emission between MEA and KS-1 TM solvents; they reported that MEA and KS-1 TM emissions were 0.8-67.5 and 0.4-23.2 ppmv, respectively, based on the fuel gas containing 0-3 ppmv of SO3.…”

In this study, a monoethanolamine aerosol growth model was developed to investigate the aerosol growth factor. Interactions among the internal conditions in an absorber were considered in this aerosol model. Additionally, an experiment was conducted to measure aerosol particle size, for collecting in-house validation data. Sucrose was used as the aerosol nuclei instead of sulfuric acid to prevent the corrosion of equipment used in the experiment. Experimental results showed that the outlet aerosol sizes increased to the same size regardless of the sucrose concentrations. The aerosol growth model was validated using the in-house experimental data. The aerosol growth model efficiently predicted the aerosol size. For investigating aerosol growth effects, particle number concentration was determined to be the primary factor affecting aerosol growth and amine emissions. When the particle number concentration increased, the aerosol size decreased, whereas the MEA emission increased.
