    • Chemical Stability and Characterization of Degradation Products of Blends of 1-(2-Hydroxyethyl)pyrrolidine and 3-Amino-1-propanol 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Francois, Maxime; Knuutila, Hanna K; Haugen, Geir; Wiig, Merete; Vernstad, Kai (Peer reviewed; Journal article, 2022)
      Aqueous amine solvents are used to capture CO2 from various flue gas sources. In this work, the chemical stability of a blend of 3-amino-1-propanol (3A1P) and 1-(2-hydroxyethyl)pyrrolidine [1-(2HE)PRLD] was studied. The ...

    • Comparison of different solvents from the solvent degradation rig With real samples 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas Magnar; Haugen, Geir; Kupfer, Rene; Brown, Nathan; Einbu, Aslak; Vernstad, Kai; Zahlsen, Kolbjørn (Journal article; Peer reviewed, 2017)

    • Evaluation of Results from SDR Campaigns and Pilot Data 

      Vevelstad, Solrun Johanne; Grimstvedt, Andreas; Haugen, Geir; Wiig, Merete; Vernstad, Kai (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)
      For ethanolamine (MEA) many degradation products have been identified and quantified, and the formation of these compounds at different process conditions should be verified. This short paper shows that lab scale experiments, ...

    • Exploration of degradation chemistry by Advanced analytical methodology 

      Grimstvedt, Andreas Magnar; Zahlsen, Kolbjørn; Vevelstad, Solrun Johanne; Vernstad, Kai; Holten, Torunn; Brunsvik, Anders (Journal article; Peer reviewed, 2017)

    • Impact of Solvent on the Thermal Stability of Amines 

      Høisæter, Karen Karolina; Vevelstad, Solrun Johanne; Braakhuis, Lucas; Knuutila, Hanna K (Peer reviewed; Journal article, 2022)
      Water-lean solvents have been proposed as a possible alternative to aqueous amine systems in postcombustion carbon capture. There is however little data available on how amine degradation is affected by different solvents. ...

    • 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 (Peer reviewed; Journal article, 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 ...

    • Multi-component analysis of monethanolamine solvent samples by FTIR 

      Grimstvedt, Andreas Magnar; Wiig, Merete; Einbu, Aslak; Vevelstad, Solrun Johanne (Journal article; Peer reviewed, 2019)
      Partial least square regression (PLS-R) methodology have been applied on dataset containing FTIR spectra and densities for a large set of MEA solvent samples. The prediction capabilities for the major compounds were tested ...

    • A review of degradation and emissions in post-combustion CO2 capture pilot plants 

      Buvik, Vanja; Høisæter, Karen Karolina; Vevelstad, Solrun Johanne; Knuutila, Hanna K (Peer reviewed; Journal article, 2021)
      Pilot plant testing of amine solvents for post-combustion CO2 capture is an essential tool for fully understanding degradation behaviour and emission profiles under realistic process conditions. This review aims to summarise ...

    • Screening of strong bicarbonate forming solvents for CO2 capture 

      Hartono, Ardi; Vevelstad, Solrun Johanne; Ciftja, Arlinda; Knuutila, Hanna K (Journal article; Peer reviewed, 2017)

    • Stability of Structurally Varied Aqueous Amines for CO2 Capture 

      Buvik, Vanja; Vevelstad, Solrun Johanne; Brakstad, Odd Gunnar; Knuutila, Hanna K (Peer reviewed; Journal article, 2021)
      Eighteen structurally varied amines were subjected to harsh oxidative conditions, and their stability was assessed and seen in the context of biological and thermal stability. Steric effects play a large role in the ...

    • Use of metal-organics based solvents for CO2 capture 

      Heyn, Richard H; Aronu, Ugochukwu Edwin; Vevelstad, Solrun Johanne; Hoff, Karl Anders; Didriksen, Terje; Arstad, Bjørnar; Blom, Richard (Journal article; Peer reviewed, 2014)
      There are a number of metal-organic compounds that can loosely be considered CA mimics and which are known to absorb CO2 directly from the atmosphere. The metal-organic complex, {Zn[N[CH2(2-py)]3](μ-OH)}2(NO3)2 (I), is one ...
