• 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 ...

    • Energy assessments of onboard CO2 capture from ship engines by MEA-based post combustion capture system with flue gas heat integration 

      Einbu, Aslak; Pettersen, Torbjørn; Morud, John; Tobiesen, Finn Andrew; Jayarathna, Chameera; Skagestad, Ragnhild; Nysæther, Gisle (Peer reviewed; Journal article, 2022)
      An early phase feasibility study was carried out for offshore CO2 capture from ship engines of a CO2 transport ship. A flexible in-house process simulator was applied in the assessments. Parametric studies of the overall ...
    • Fluidized bed calcination of cement raw meal: Laboratory experiments and CPFD simulations 

      Samani, Nastaran Ahmadpour; Jayarathna, Chameera; Tokheim, Lars-Andre (Peer reviewed; Journal article, 2020)
      The chemical and thermal processes associated with the decarbonation and fuel combustion in the cement kiln process produce a large amount of carbon dioxide (CO2) contributing with around 8 % of the global CO2 emissions. ...
    • Improved multi-stage cross-flow fluidized bed classifier 

      Jayarathna, Chameera; Balfe, Michael; Moldestad, Britt Margrethe Emilie; Tokheim, Lars-Andre (Peer reviewed; Journal article, 2019)
      In the present work, improvements to a novel fluidized bed solids classification system previously published by Jayarathna et al. are discussed (Jayarathna et al., 2018 [1]). The system is designed for a high temperature ...
