“…However, in a round-robin test conducted in the OCTAVIUS project, this method did not give reliable quantification of the nitrosamine content in the range of 0.1−1.2 mg N-NO/kg sample. 123 The same work shows that the laboratories were able to give reliable results for nitrosamine in the sulfamic matrix. Further, only a few laboratories could analyze low levels of nitrosamines in the solvent matrix and the whole specter of nitrosamines requested in that work.…”

The chemical stability of aqueous amines is an essential property to study before new amines are introduced in pilot plants, to reduce risks related to the operation, cost and environment. There are no standard methods for studying degradation and no standardized way of knowing which components to search for. This work will give an overview of the current status of amine degradation research with recommendations for further work within this field. Degradation of aqueous amines in the CO 2 absorption process will always occur, though some amines are more stable than others. Degradation leads to compounds with various functional groups, some of which require monitoring from an environmental or health perspective. Future experimental activity should focus on closing the knowledge gaps. Improved knowledge could help to better predict and monitor degradation, help design better mitigation technologies, and minimize solvent degradation by finetuning the plant operation.

“…The total nitrosamine method has higher uncertainty than the methods for the specific nitrosamines. A round Robin test for analyses of specific nitrosamine and total nitrosamine was previously reported by Fraboulet et al, which showed considerable variation between different laboratories regarding their capabilities to analyze requested components and provide quantitative data. They concluded that the most reliable results were obtained for the specific nitrosamine in synthetic solutions and that the total nitrosamine method overestimated the results.…”

Aqueous amine solvents are used to capture CO2 from various flue gas sources. In this work, the chemical stability of a blend of 3-amino-1-propanol (3A1P) and 1-(2-hydroxyethyl)pyrrolidine [1-(2HE)PRLD] was studied. The chemical stability tests were conducted both in batch and cycled systems using various oxygen and NOx concentrations, additives (iron), and temperatures. In the thermal degradation experiments with CO2 present, the blend was more stable than the primary amines [(3A1P or monoethanolamine (MEA)] but less stable than the tertiary amine 1-(2HE)PRLD alone. Similar stability was observed between MEA, 3A1P, and the blend in the batch experiments at medium oxygen concentration (21% O2) and no iron present. 1-(2HE)PRLD was more stable. However, the presence of high oxygen concentration (96% O2) and iron reduced the stability of 1-(2HE)PRLD significantly. Furthermore, in the case of the blend, the chemical stability increased with increasing promoter concentration in batch experiments. During the cyclic experiment, the amine loss for the blend was similar to what was previously observed for MEA (30 wt %) under the same conditions. A thorough mapping of degradation compounds in the solvent and condensate samples resulted in the identification and quantification of 30 degradation compounds. The major components in batch and cycled experiments varied somewhat, as expected. In the cyclic experiments, the major components were ammonia, 3-(methylamino)-1-propanol (methyl-AP), N,N′-bis(3-hydroxypropyl)-urea (AP-urea), pyrrolidine, formic acid (formate), and N-(3-hydroxypropyl)-glycine (HPGly). Finally, in this paper, formation pathways for the eight degradation compounds (1,3-oxazinan-2-one, AP-urea, 3-[(3-aminopropyl)amino]-1-propanol, tetrahydro-1-(3-hydroxypropyl)-2(1H)-pyrimidinone, methyl-AP, N-(3-hydroxypropyl)-formamide, N-(3-hydroxypropyl)-β-alanine, and HPGly) are suggested.
