Nitrosamines (NSAs) and nitramines (NAs) are identified as possible degradation products from amine-based post-combustion CO2-capture (PCCC). Selected NSAs and NAs were subjected to aerobic and anaerobic biodegradation studies. In a screening study with 20 μg/L NSAs and NAs at 20 °C, only NSAs ...

Two of the main challenges in post-combustion CO2 capture with ethanolamine are solvent degradation and material corrosion. It has been shown that there is a correlation between degradation and corrosion. The present paper examines this correlation by studying the effect of 10 MEA degradation produc...

Amine solvents used in post combustion CO2 capture (PCCC) plants react with NOx, forming carcinogenic nitrosamine and nitramine compounds. These can be emitted to the atmosphere, undergoing deposition to aquatic and terrestrial environments. In the current study, the hydrolytic and photolytic degrad...

...n this study biodegradation of nitramines were investigated at low concentrations in a biodegradation simulation test. The experiments were conducted with natural lake and river water as bacterial inocula, and over periods of 56 days (2 months). Biotransformation was determined by liquid chromatogra...
