• Combined calcination and CO2 capture in cement clinker production by use of electrical energy 

      Tokheim, Lars-Andre; Mathisen, Anette; Øi, Lars Erik; Jayarathna, Chameera; Eldrup, Nils Henrik; Gautestad, Tor (SINTEF proceedings;4, Chapter; Peer reviewed, 2019)
      The technical feasibility of electrifying the calcination process in a precalciner cement kiln system was assessed by studying different electrification concepts. Resistance-based heating was selected as it requires no CO2 ...

    • Impact of Uncertainty of Physical Properties on CO2 Absorption Design 

      Øi, Lars Erik; Karunarathne, Sumudu (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)
      The mass transfer coefficients, interfacial area and pressure drop of a packed bed are essential properties that need to be evaluated prior to the design of a CO2 absorption column. Various mathematical models have been ...
    • Simulation of Condensation in Compressed Raw Biogas Using Aspen HYSYS 

      Øi, Lars Erik; Hovland, Jon (Journal article; Peer reviewed, 2018)
      Raw biogas typically contains 60 % methane, 40 % CO2, small amounts of other components and is saturated with water. It is a question whether raw biogas can be compressed to high pressures without condensation. The aim of ...
    • 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 ...
