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 ... -
Determination of the mechanism of the reaction between CO2 and alkanolamines.
Awais, Muhammad (Master thesis, 2013)Emission control of greenhouse gases especially CO2 has become an environmental challenge. CO2 capture by absorption in amine is so far the only CCS technique that has been industrially acknowledged. Chemical absorption ... -
Effect of Amine Volatility on Aerosol Droplet Development in Absorption Columns
Majeed, Hammad; Knuutila, Hanna K; Hillestad, Magne; Svendsen, Hallvard Fjøsne (Journal article; Peer reviewed, 2017)In absorption processes aerosols are generated by spontaneous condensation or desublimation processes in supersaturated gas phases. Amine volatility is a vital screening parameter for amines to be used in CO2 capture. ... -
Effect of MEA's degradation products on corrosion at CO2 capture plants
Fytianos, Georgios; Grimstvedt, Andreas Magnar; Knuutila, Hanna; Svendsen, Hallvard Fjøsne (Journal article; Peer reviewed, 2014)Amine degradation and corrosion can be a severe operational problem in the CO2 absorption process. In this paper the effect of MEA's degradation products on corrosion is studied. Different solutions of MEA 30wt% containing ... -
Effect of water wash on mist and aerosol formation in absorption column
Majeed, Hammad; Svendsen, Hallvard Fjøsne (Journal article; Peer reviewed, 2018)Environmental issues regarding solvent emissions can hamper the realization of state of the art post combustion CO2 capture (PCCC). These emissions stem from the emitted flue gas from which CO2 has been recovered and are ... -
