“…Nitrosamines have been detected in post-combustion CO 2 capture plant for soda ash production equipped with a deep-polishing SO 2 scrubber at Trona, California (Strazisar et al, 2003). About 5-47 ng/Nm 3 have been reported for the emission campaign at Maasvlakte (da Silva et al, 2013). A number of pathways and mechanisms have been proposed for the formation of nitrosamines from nitrate, nitrite, and amines in neutral and acidic conditions (Lv et al, 2008;Masuda et al, 2000;Sun et al 2010).…”

The formation and any emission of nitrosamines in a post-combustion CO capture process are of great interest over the past few years even though its concentration is quite low. In the present research, bench scale nitrosation experiments were conducted using morpholine, a representative of secondary amines, with NO 2 gas and flue gas. Laboratory experiments with 5 M morpholine with 100 ppm NO 2 gas resulted in 88 µg/g nitrosomorpholine (NSMO) in 6 h and 450 µg/g in 24 h. However, coal derived flue gas gave only about 7 µg/g NSMO in 24 h. To prove the inhibitory effect from SO 2 in the flue gas, experiments were conducted with diluted NO 2 gas blended with SO 2 gas in the feed stream. Formation of NSMO was inhibited by about 53.3% when equal concentrations of SO 2 and NO 2 existed compared with the same concentration of NO 2 gas diluted with N 2. The inhibitory effect of SO 2 gas was found to be linear with its concentration. Apart from that, the addition of various inhibitors to the amine solution was also evaluated and isoascorbic acid was found as the best with 86% inhibition activity under the test conditions. Isoascorbic acid was further examined both under simulated CO 2 scrubber and stripper conditions indicating good stability and inhibition performance.

“…Besides, organic compound (NH4)2SO4 dominates a great proportion (~ 87%) in oxidative degradation products. In addition, another study reports that the formation of nitramines and nitrosamines through NOx nitrosation are up to 5 ~ 47 ng/Nm 3 under MEA-based pilot plant conditions (da Silva et al, 2013). From the table, we can see most of the components are biodegradable.…”

The large-scale implementation of amine-based carbon capture processes requires the development of sustainable handling technology of the waste effluents. The generated wastewater contains significant amounts of ammonia and toxic degradation products, nitroamines and nitrosamines. They both pose great threats to the ecological environment and human health. Monoethanolamine (MEA) is one of the most commonly used absorption solvents in the post-combustion carbon capture process. In order to make a better management strategy, the waste components and the pathways of MEA degradation are demonstrated based on different reference papers and case studies. Moreover, the toxicity and environmental impact of the degradation products are evaluated. The goal of this review is to elucidate potential technologies that can either eliminate the hazardous nature of the amine waste or convert it into marketable products. We categorize these technologies as waste disposal, recycle, reuse, and chemical/biological treatment method. Several applications with a focus on biodegradation technique are examined according to their amine removal performance. The results reveal that bioconversion is a promising technique for handling amine-based wastewater at large-scale.

“…This system utilized hot and wet measurement principle, which ensures that the analysis was carried out on a representative sample. Previous studies showed that this technique was suitable for monitoring both inorganic and organic emissions from pilot plants (da Silva et al 2013;Khakharia et al 2014;Mertens et al 2013). Unfortunately, AEEA emission measurements were impossible due to FTIR gas analyser limitations.…”

“…It is worth mentioning that mist formation depends in high extent on the presence of condensation nuclei, such as particulate matter, soot, SO 2 , NO 2 , H 2 SO 4 . These fine particles contribute to the heterogeneous nucleation being a dominant mechanism of aerosol formation in most industrial gas cleaning processes (Kamijo et al 2013;da Silva et al 2013;Khakharia et al 2013).…”

Amine post-combustion carbon capture technology is based on washing the flue gas with a solvent that captures CO 2 . Thus, a small fraction of this solvent can be released together with the cleaned flue gas. This release may cause environmental concerns, both directly and indirectly through subsequent solvent degradation into other substances in the atmosphere. The paper presents the ammonia emission from CO 2 capture pilot plant (1 tonne CO 2 per day) using 40 wt% aminoethylethanolamine solvent, along with the efficiency of the water wash unit. In addition, the temperature effect of lean amine entering the absorber on ammonia emission was studied. Furthermore, the concentrations of other compounds such as SO 2 , SO 3 , NO 2 , CS 2 and formaldehyde were monitored. The literature review on the NH 3 emission from a pilot plant using aminoethylethanolamine solvent has not been published. The results show that the main source of ammonia emission is the absorber and that emission (in the range 27-50 ppm) corresponds to typical NH 3 release from CO 2 capture pilot plant using an amine solvent. The emission of amines and amine degradation products is a complex phenomenon which is difficult to predict in novel solvents, and for this reason the significance of new solvents testing in a pilot scale has been highlighted.
