      Tabib, Mandar; Cloete, Schalk Willem Petrus; Morud, John; Lysberg, Magne; Amini, Shahriar (Chapter, 2017)
      A validated multi-domain 1D particle-reactor model has been developed to simulate packed bed reactor operation. Two main components of the model are: (1) a particle model for simulating the radial distribution of chemical ...

    • A multi-scale model for oxygen carrier selection and reactor design applied to packed bed chemical looping combustion 

      Tabib, Mandar; Morud, John; Johansen, Stein Tore; Amini, Shahriar (SINTEF Proceedings;1, Chapter, 2015)
      Proper selection of a catalyst shape (or a particle shape) can improve the performance of a gas-solid packed bed reactor. The particle shape affects the packing structure and the transport phenomena within the packed bed. ...

    • A multi‐domain 1D particle‐reactor model for packed bed reactor applications 

      Tabib, Mandar; Cloete, Schalk; Morud, John; Lysberg, Magne; Amini, Shahriar (SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)
      A validated multi-domain 1D particle-reactor model has been developed to simulate packed bed reactor operation. Two main components of the model are: (1) a particle model for simulating the radial distribution of chemical ...

    • COMPOSITE: A concept for high efficiency power production with integrated CO2 capture from solid fuels 

      Larring, Yngve; Cloete, Schalk Willem Petrus; Giuffrida, Antonio; Romano, Matteo C.; Chiesa, Paolo; Morud, John; Pishahang, Mehdi; Chikukwa, Actor; Amini, Shahriar; Tobiesen, Finn Andrew (Peer reviewed; Journal article, 2017)
      The COMPOSITE concept combines packed bed chemical looping combustion (PBCLC) with chemical looping for oxygen production (CLOP) in an integrated gasification combined cycle for high efficiency power production. Detailed ...

    • 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 ...

    • Mass transfer between bubbles and seawater 

      Olsen, Jan Erik; Dunnebier, Dorien; Davies, Emlyn John; Skjetne, Paal; Morud, John (Peer reviewed; Journal article, 2017)
      Mass transfer between bubbles and seawater is an important mechanism when determining how much gas reaches the atmosphere from gas sources at the seabed. The mass transfer coefficient is a governing parameter for the ...

    • A Novel Swing Adsorption Reactor Cluster (SARC) for Cost Effective Post-combustion CO2 Capture: A Thermodynamic Assessment 

      Zaabout, Abdelghafour; Romano, Matteo C.; Cloete, Schalk Willem Petrus; Giuffrida, Antonio; Morud, John; Chiesa, Paolo; Amini, Shahriar (Peer reviewed; Journal article, 2017)
      The SARC consists of a number of standalone reactors where a solid sorbent is carbonated by a flue gas and regenerated by a combination of vacuum and temperature swing. Efficiency is maximized through heat integration ...

    • Numerical approach for generic three‐phase flow based on cut‐cell and ghost fluid methods 

      Dang, Son Tung; Meese, Ernst A.; Morud, John; Johansen, Stein Tore (Journal article; Peer reviewed, 2019)
      In this paper, we introduce numerical methods that can simulate complex multiphase flows. The finite volume method, applying Cartesian cut‐cell is used in the computational domain, containing fluid and solid, to conserve ...

    • Prospects of the Novel CSAR Concept for Fully Electric or Flexible Electric–Thermal Hybrid CO2 Capture from CHP Plants 

      Cloete, Schalk Willem Petrus; Dhoke, Chaitanya; Bonalumi, Davide; Morud, John; Giuffrida, Antonio; Romano, Matteo Carmelo; Zaabout, Abdelghafour (Peer reviewed; Journal article, 2023)
      Momentum is gathering behind the goal of achieving net-zero CO2 emissions by 2050 in Europe and around the world. Negative emissions via biomass or waste combustion with CO2 capture can make net zero considerably easier ...

    • Simplified model description of a CLOP reactor for system simulation and analysis
