Decomposition of nitrosamines in aqueous monoethanolamine (MEA) and diethanolamine (DEA) solutions with UV-radiation

Knuutila, Hanna; Svendsen, Hallvard Fjøsne; Asif, Naveed (Journal article; Peer reviewed, 2014)

CO2 capture based on chemical absorption using amine solutions is considered to be the most feasible way to remove CO2 from low pressure sources. However, amines, when exposed to nitrous oxides, may form nitrosamines which ...
Destruction of nitrosoamines with UV-light

Knuutila, Hanna; Svendsen, Hallvard Fjøsne; Asif, Naveed (Journal article; Peer reviewed, 2013)

In this paper the destruction of nitrosamines (NDMA and NDELA) in 30wt% MEA, 50wt% DEA and water wash solutions with UV-irradiation are presented and linked to measured penetration depths of UV- light. The results show ...
Formation et destruction de NDELA dans des solutions de 30%m de MEA (Monoétha-nolamine) et de 50%m de DEA (Diéthanolamine)

Knuutila, Hanna; Asif, Naveed; Vevelstad, Solrun Johanne; Svendsen, Hallvard Fjøsne (Journal article; Peer reviewed, 2014)

The formation of nitrosodiethanolamine (NDELA) in a lab scale pilot was studied by feeding known amounts of nitrogen oxide and nitrogen dioxide into the gas entering the absorber. In the same pilot, the destruction by ...
