• 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 ...
    • Kvantitering av nitrogenholdige degraderingsprodukter i aminløsninger 

      Laukvik, Marianne; Laukvik, Tonje (Bachelor thesis, 2019)
      I lys av økt mengde klimagasser i atmosfæren, har CO2-fangst blitt et stadig viktigere satsningsområde. Store mengder CO2 emitteres ut i atmosfæren som følge av intensivert forbrenning av fossilt brennstoff. Behovet for ...
    • Measurement and prediction of oxygen solubility in post-combustion CO2 capture solvents 

      Buvik, Vanja; Bernhardsen, Ida; Figueiredo, Roberta V.; Vevelstad, Solrun Johanne; Goetheer, Earl L.V.; van os, peter (Peer reviewed; Journal article, 2020)
      This work aims to understand oxygen solubility in pure and aqueous amine solvents for CO2 capture. Commercially available dissolved oxygen sensors were studied to evaluate whether these can be used for measuring oxygen ...
    • 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 ...
    • Synthesis of conjugated unsaturated Amino Acids 

      Buvik, Vanja (Master thesis, 2016)
      Of the three main groups of biomolecules - lipids, carbohydrates and proteins - lipids and carbohydrates containing polyene functionalities have already been investigated. This thesis describes a first approach to the ...
    • Vapor Liquid Equilibrium Measurements of Two Promising Tertiary Amines for CO2 Capture 

      Pinto, Diego Di Domenico; Zahraee, Znar; Buvik, Vanja; Hartono, Ardi; Knuutila, Hanna K (Journal article; Peer reviewed, 2019)
      Post combustion CO2 capture is still a rather energy intense, and therefore expensive, process. Much of the current research for reducing the process energy requirements is focused on the regeneration section. A good ...
