• Oxygen Effects in Anaerobic Digestion II 

      Botheju, Deshai; Lie, Bernt; Bakke, Rune (Journal article, 2010)
      Standard models describing bio-gasification using anaerobic digestion do not include necessary processes to describe digester dynamics under the conditions of oxygen presence. Limited oxygenation in anaerobic digestion can ...
    • Simulation and Cost Comparison of CO2 Liquefaction 

      Øi, Lars Erik; Eldrup, Nils Henrik; Adhikari, Umesh; Bentsen, Mathias Håvåg; Badalge, Jayalanka Chathurangani Liyana; Yang, Songbo (Journal article; Peer reviewed, 2016)
      Liquefaction of CO2 is an intermediate step for storage or ship transport. Two processes are suggested. The traditional method is based on external refrigeration and the other is an integrated refrigeration process. In the ...
    • Simulation of improved absorption configurations for CO2 capture 

      Øi, Lars Erik; Aromada, Solomon Aforkoghene (Conference object; Peer reviewed, 2015-11-25)
      The most well-known technology for post combustion CO2 capture from exhaust gas is absorption in an amine-based solvent followed by desorption. The drawback of this method is the high heat consumption required for desorption. ...
