• Simulation of Condensation in Biogas containing Ammonia 

      Øi, Lars Erik; Bråthen, Terje; Hovland, Jon (Peer reviewed; Journal article, 2021)
      Condensation in raw biogas during compression is a problem because the CO2 and water in the liquid phase is very corrosive. Raw biogas typically contains 60 mol-% methane, 40 mol-% CO2, is saturated with water and may ...
    • Simulation of dew points in raw biogas using PR and SRK equations of state : 

      Bråthen, Terje; Øi, Lars Erik; Hovland, Jon (Peer reviewed; Journal article, 2019)
      Biogas contains mainly methane, but raw biogas can contain large amounts of CO2 and is normally saturated with water. Condensation, especially during compression, may lead to operational problems. The aim of this work is ...
    • Work Placement in Higher Education – Bridging the Gap between Theory and Practice 

      Immerstein, Robert; Hasleberg, Harald; Bråthen, Terje (Peer reviewed; Journal article, 2019)
      During the engineering education, the focus is on theoretical knowledge and less on the practical competence to be a professional engineer. To lead higher education into the future, it is critical to develop models and ...
