• CCS on Offshore Oil and Gas Installation - Design of Post Combustion Capture System and Steam Cycle 

      Nord, Lars O.; Anantharaman, Rahul; Chikukwa, Actor; Mejdell, Thor (Journal article; Peer reviewed, 2017)
      Most of the released CO2 on offshore oil and gas installation originates from the gas turbines that power the installations. For certain offshore installations, CO2 capture and storage (CCS) could be an alternative to ...
    • 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 ...
    • Enzyme Carbonic Anhydrase Accelerated CO2 Absorption in Membrane Contactor 

      Kim, Taek Joong; Lang, Alexander; Chikukwa, Actor; Sheridan, Edel; Dahl, Paul Inge; Leimbrink, Mathias; Skiborowski, Mirko; Roubroeks, Johannes (Peer reviewed; Journal article, 2017)
      Membrane contactors offer a promising alternative to conventional CO2 absorption processes using columns. In a membrane contactor the advantages of absorption technology and membrane technology are combined as direct contact ...
    • Phase Equilibrium Measurements of Ammonia Based CO2 Capture Solvents with FTIRr for Gas Phase Analysis 

      Kim, Inna; Chikukwa, Actor; Kvamsdal, Hanne ,; Hoff, Karl Anders; Mejdell, Thor; Haugen, Geir (SINTEF Proceedings;7, Chapter; Peer reviewed; Conference object, 2021)
      Vapor-liquid-solid equilibrium (VLSE) was measured for four solvents (blends A-D) at atmospheric pressure in a low-temperature setup at 20 oC and at 20, 35, and 55 oC for blend E. The blends are ammonia-based aqueous ...
    • Simplified model description of a CLOP reactor for system simulation and analysis 

      Morud, John; Tobiesen, Finn Andrew; Cloete, Schalk Willem Petrus; Larring, Yngve; Chikukwa, Actor; Pishahang, Mehdi (Peer reviewed; Journal article, 2017)
      In order to perform overall system simulations and optimization at the flowsheet level, simplified models of process units are required. We present a simplified model of the CLOP reactor (chemical looping for oxygen ...
