This critical review addresses the atmospheric gas phase and aqueous phase amine chemistry that is relevant to potential emissions from amine-based carbon capture and storage (CCS). The focus is on amine, nitrosamine and nitramine degradation, and nitrosamine and nitramine formation processes. A comparison between the relative importance of the various atmospheric sinks for amines, nitrosamines and nitramines is presented.

“…N-nitrosodi-n-propylamine is not expected to undergo abiotic degradation under the conditions found in natural waters (Callahan et al 1979, Saunders and Mosier 1980. The dominant removal process for N-nitrosodi-n-propylamine in surface water is probably 44 5.…”

“…A study of low levels (0.65 ppm) of N-nitrosodi-n-propylamine in lake water resulted in a photolytic half-life of about 2.5 hours. The major photoproduct was found to be n-propylamine, but the formation of di-n-propylamine was also observed (Saunders and Mosier 1980). Beyond the reach of sunlight it appears that N-nitrosodi-n-propylamine would be subject to slow microbial degradation in aerobic waters (Tabak et al 1981, Tate andAlexander 1975).…”

Photolysis Rate of the Herbicide Naproanilide Exposed to Sunlight in Water

The photolysis rate (conversion per unit energy) of naproanilide (2-(2-naphthoxy)propionanilide) in water was related with sunlight energy (below 340 nm). This relation was expressed by the following equation under seasonal sunlight conditions in an FRA-greenhouse. P=P' X exp (-K X E'), where P is the concentration of remaining naproanilide, P' is an initial concentration of naproanilide, K is a photolysis constant and E' is the energy (cal/cm2) of sunlight (below 340nm). The energy required to photodecompose the 50% of the starting material (PL50i cal/cm2) was expressed by the following equation. PL50=0.693/x. The PL50 value of naproanilide was 10.3 mcal/cm2 (below 340 nm) and reproducible in the FRAgreenhouse. Since the half-life period of naproanilide by photolysis depends on experimental conditions, such as weather and solar altitude, it would be better to use the PL50 value rather than the half-life period to express the reliable photostability of naproanilide. The photolysis rate of naproanilide was pH-independent in water, and slower in 02-free water than in natural water. Sunlight energy (below 340nm) was measured with a UV radio meter UVR-254 (Tokyo Kagaku Kikai Co., Ltd.) in the FRA-greenhouse at Chigasaki City (13930' east, 3529' north). These data are useful to estimate the photostability of naproanilide in water under natural sunlight conditions.
