• 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 ...
    • 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 ...
