• Important Aspects Regarding the Chemical Stability of Aqueous Amine Solvents for CO2 Capture 

      Vevelstad, Solrun Johanne; Buvik, Vanja; Knuutila, Hanna K; Grimstvedt, Andreas Magnar; Silva, Eirik Falck da (Journal article; Peer reviewed, 2022)
      The chemical stability of aqueous amines is an essential property to study before new amines are introduced in pilot plants, to reduce risks related to the operation, cost and environment. There are no standard methods for ...
    • 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 ...
    • Modeling Differential Enthalpy of Absorption of CO2 with Piperazine as a Function of Temperature 

      Gupta, Mayuri; Silva, Eirik Falck da; Svendsen, Hallvard Fjøsne (Peer reviewed; Journal article, 2022)
      Temperature-dependent correlations for equilibrium constants (ln K) and heat of absorption (ΔHabs) of different reactions (i.e., deprotonation, double deprotonation, carbamate formation, protonated carbamate formation, ...
    • 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 ...
