• Accelerated hydrolysis method for producing partially degraded polyester microplastic fiber reference materials 

      Sarno, Antonio; Olafsen, Kjell; Kubowicz, Stephan; Karimov, Fuad; Sait, Shannen; Sørensen, Lisbet; Booth, Andy (Peer reviewed; Journal article, 2020)
      Microplastic fibers (MPFs) from textiles significantly contribute to the microplastic (MP) load in many environmental matrices and have been shown to negatively impact the organisms therein. Most fate and effect studies ...
    • 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 ...
    • Degradation and emission results of amine plant operations from MEA testing at the CO2 technology centre Mongstad 

      Morken, Anne Kolstad; Pedersen, Steinar; Kleppe, Eirik Romslo; Wisthaler, Armin; Vernstad, Kai; Ullestad, Øyvind; Flø, Nina Enaasen; Faramarzi, Leila; Hamborg, Espen Steinseth (Peer reviewed; Journal article, 2017)
      In 2015, the CO2 Technology Centre Mongstad (TCM DA), operated a test campaign using aqueous monoethanolamine (MEA) solvent at 30 wt%. The main objective was to demonstrate and document the performance of the TCM DA Amine ...
    • 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 ...
    • Minority carrier lifetimes in Cz-Si wafers with intentional V-I transitions 

      Søndenå, Rune; Ryningen, Birgit; Juel, Mari (Peer reviewed; Journal article, 2017)
      A p-type Cz-Si crystal has been pulled with varying pulling speed in order to produce wafers containing two distinct regions; A region with silicon self-interstitial defects, and a vacancy dominated region. Band-to-band ...
    • 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 ...
