• Corrosion and degradation in MEA based post-combustion CO2 capture 

      Fytianos, Georgios; Ucar, Seniz; Grimstvedt, Andreas Magnar; Hyldbakk, Astrid; Svendsen, Hallvard Fjøsne; Knuutila, Hanna K. (Journal article; Peer reviewed, 2016)
      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 ...
    • Corrosion Evaluation of MEA Solutions by SEM-EDS, ICP-MS and XRD 

      Fytianos, Georgios; Ucar, Seniz; Grimstvedt, Andreas Magnar; Svendsen, Hallvard Fjøsne; Knuutila, Hanna K. (Journal article; Peer reviewed, 2016)
      The target of this work is to evaluate three analytical techniques, ICP-MS, SEM-EDS and XRD, which can be applied in corrosion monitoring of ethanolamine based post-combustion CO2 capture plants. The work is based on ...
    • DT2_2017_1 Degradation and corrosion of amines (from a structural perspective) 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Buvik, Vanja (Research report, 2017)
      Degradation and corrosion of amine solutions in post combustion CO2 capture plants increases the cost of the process due to operational problems, the need for high quality material in the plant and reduction of the solvent's ...
    • 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 ...
    • Influence of experimental setup on amine degradation 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Knuutila, Hanna; Silva, Eirik Falck da; Svendsen, Hallvard Fjøsne (Journal article; Peer reviewed, 2014)
      Chemical stability of amines under CO2 capture conditions is a well known problem both for process operability and related to economy and environmental issues. Many degradation studies have been conducted under different ...
    • Oxidative degradation of 2-ethanolamine: The effect of oxygen concentraton and temperature on product formation 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Elnan, Jørund; Silva, Eirik Falck da; Svendsen, Hallvard Fjøsne (Journal article; Peer reviewed, 2013)
      Oxidative degradation experiments on 2-ethanolamine (MEA) were performed at four different oxygen concentrations and at two temperatures. MEA loss and degradation product build-up were measured. Increasing the temperature ...
    • Oxidative degradation of amines using a closed batch system 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Einbu, Aslak; Knuutila, Hanna; Silva, Eirik Falck da; Svendsen, Hallvard Fjøsne (Journal article; Peer reviewed, 2013)
      Oxidative degradation experiments on five amines and two amino acids were performed in a new closed setup at atmospheric pressure. For most of the amines/amino acids significant degradation was not present under these ...
    • Thermal degradation on already oxidatively degraded solutions 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Knuutila, Hanna; Svendsen, Hallvard Fjøsne (Journal article; Peer reviewed, 2013)
      CO2 capture with alkanolamines has been in use since 1930, where 2-ethanolamine (MEA) is the most studied absorbent for post-combustion. In order to prevent degradation, it is important to understand the degradation ...
