      A campaign on carbon capture from biomass flue gas was carried out at Tiller pilot plant during 30th September - 8th November 2019. Biomass was supplied by Drax power station. SRD of 3.57MJ/kgCO2 was obtained for MEA, ...
    • Evaluation of energetic benefit for solid-liquid phase change CO2 absorbents 

      Aronu, Ugochukwu Edwin; Kim, Inna; Haugen, Geir (Peer reviewed; Journal article, 2014)
      A preliminary evaluation of desorption energy requirement for a precipitating system shows that precipitate formation results to a decrease in desorption energy requirement for a precipitating amino acid salt system compared ...
    • Influence of substitution of water by organic solvents in amine solutions on absorption of CO2 

      Garcia, Monica; Knuutila, Hanna K; Aronu, Ugochukwu Edwin; Gu, Sai (Peer reviewed; Journal article, 2018)
      Aqueous amine solutions are the most used solvents for chemical absorption of CO2. Substituting part of the water by organic solvents in aqueous amine solutions aims to take advantage of the lower partial pressure and ...
    • Liquid-solid Solubility in AMP-KSAR-CO2-H2O System 

      Aronu, Ugochukwu Edwin; Ma, Xiaoguang (Peer reviewed; Journal article, 2017)
      Solid-liquid solubility of an example novel precipitating solvent system (NPSS); an aqueous blend of AMP and KSAR with and without CO2 were studied to determine the crystallization and dissolution regimes as well as the ...

      Vevelstad, Solrun Johanne; Kim, Inna; Grimstvedt, Andreas Magnar; Wiig, Merete; Aronu, Ugochukwu Edwin (Journal article; Peer reviewed, 2017)
    • Understanding precipitation in amino acid salt systems at process conditions 

      Aronu, Ugochukwu Edwin; Ciftja, Arlinda Fejzo; Kim, Inna; Hartono, Ardi (Peer reviewed; Journal article, 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 40°C have shown that at high concentrations, amino ...
    • 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 ...
