    • Modeling of oxidative MEA degradation 

      Pinto, Diego Di Domenico; Brodtkorb, Thea Wilhelmine; Vevelstad, Solrun Johanne; Knuutila, Hanna; Svendsen, Hallvard Fjøsne (Journal article; Peer reviewed, 2014)
      Considerable amount of work had been recently done researching the degradation of solvents for CO2 post combustion capture, especially for the benchmark solvent MEA. The degradation of the solvent can cause plant corrosion ...

    • Overall Process Analysis and Optimisaton for CO2 Capture from Coal Fired Power Plants basen on Phase Change Solvents Forming Two Liquid Phases 

      Liebenthal, Ulrich; Pinto, Diego Di Domenico; Monteiro, Juliana Garcia Moretz-Sohn; Svendsen, Hallvard Fjøsne; Kather, Alfons (Journal article; Peer reviewed, 2013)
      In this work the potential of a novel post-combustion CO2 capture process is analysed with respect to the integrated overall process. As solvent a blend of two amines (DEEA/MAPA) which forms two liquid phases under CO2 ...

    • Oxygen and temperature effect on formation of degradation compounds from MEA 

      Vevelstad, Solrun Johanne; Johansen, Maren T; Knuutila, Hanna; Svendsen, Hallvard Fjøsne (Journal article; Peer reviewed, 2014)
      Liquid phase degradation of MEA and the formation of 8 degradation compounds were studied at 4 different oxygen concentrations and three different temperatures. Liquid phase total nitrogen was determined and compared with ...

    • Performance of MAPA promoted tertiary amine systems for CO2 absorption: Influence of alkyl chain length and hydroxyl groups 

      Bernhardsen, Ida Mortensen; Krokvik, Iris Renate Tøkje; Jens, Klaus-Joachim; Knuutila, Hanna K (Journal article; Peer reviewed, 2017)
      Absorption and desorption of CO2 into five aqueous tertiary amine solvents and their blends with MAPA were studied using a screening apparatus. Results showed that MAPA significantly enhanced both CO2 absorption rate and ...

    • Promoted Strong Bicarbonate Forming Solvents for CO2 Capture 

      Hartono, Ardi; Vevelstad, Solrun Johanne; Kim, Inna; Rennemo, Rune; Knuutila, Hanna K (Journal article; Peer reviewed, 2017)
      Effect of different promoters on performance of two bicarbonate forming solvents (HS1 and HS2) was studied in this work and results compared with the performance of 30 wt% MEA and CESAR1 solvents. Based on the results from ...

    • 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 ...

    • Understanding precipitation in amino acid salt systems at process conditions 

      Aronu, Ugochukwu Edwin; Ciftja, Arlinda Fejzo (Journal article; Peer reviewed, 2013)
      Rapid screening experiment has been used to acquire first-hand information on the precipitation characteristics of 14 aqueous amino acid salt systems. Absorption tests at 40o C have shown that at high concentrations, amino ...
