      Romano, Matteo C.; Anantharaman, Rahul; Arasto, Antti; can Ozcan, Dursun; Ahn, Hyungwoong; Dijkstra, Jan Wilco; Carbo, Michiel; Boavida, Dulce (Peer reviewed; Journal article, 2013)
      The great majority of the research on CO2 capture worldwide is today devoted to the integration of new technologies in power plants, which are responsible for about 80% of the worldwide CO2 emission from large stationary ...
    • Application range of the HEM approach for CO2 expansion inside two-phase ejectors for supermarket refrigeration systems 

      Palacz, Michal; Smolka, Jacek; Fic, Adam; Bulinski, Zbigniew; Nowak, Andrzej J.; Banasiak, Krzysztof; Hafner, Armin (Peer reviewed; Journal article, 2015)
      In this study, the accuracy of the homogeneous equilibrium (HEM) applied to 3-D CFD-based simulations of CO2 expansion inside two-phase ejectors is presented. The HEM approach previously reported in the literature were ...
    • Depressurization of CO2 in a pipe: Effect of initial state on non-equilibrium two-phase flow 

      Log, Alexandra Metallinou; Hammer, Morten; Deng, Han; Austegard, Anders; Hafner, Armin; Munkejord, Svend Tollak (Peer reviewed; Journal article, 2023)
      It is key in several industrial applications to accurately describe rapid depressurization of liquid and dense phase states. Examples include refrigeration systems, nuclear reactor cooling and capture and storage (CCS). ...
    • Energy and Cost Evaluation of A Low-temperature CO2 Capture Unit for IGCC plants 

      Berstad, David Olsson; Roussanaly, Simon; Skaugen, Geir; Anantharaman, Rahul; Nekså, Petter; Jordal, Kristin (Peer reviewed; Journal article, 2014)
      The application of CO2 capture by liquefaction has been investigated for an integrated gasification combined cycle (IGCC). Two configurations of the process are developed–one supplying CO2 at conditions suitable for pipeline ...
    • European power market analyses to be carried out within FME ZEN. ZEN deliverable D5.3.1 for 2017 

      Wolfgang, Ove (Zen Report;1, Research report, 2018)
      Local energy solutions such as the utilization of local renewable energy resources, and increased energy efficiency, are important for being able to reduce European greenhouse gas emissions to amounts that are in line e.g. ...
    • Evaluation of SPUNG* and Other Equations of State for Use in Carbon Capture and Storage Modelling 

      Wilhelmsen, Øivind; Skaugen, Geir; Jørstad, Oddvar; Li, Hailong (Journal article; Peer reviewed, 2012)
      In this work, Equations of State (EoS) relevant for carbon capture and storage modelling have been evaluated for pure CO2 and CO2-mixtures with particular focus on the extended corresponding state approach, SPUNG/SRK. Our ...
    • Low carbon power generation for offshore oil and gas production 

      Voldsund, Mari; Reyes Lua, Adriana; Fu, Chao; Ditaranto, Mario; Nekså, Petter; Mazzetti, Marit Jagtoyen; Brekke, Olaf; Bindingsbø, Arne Ulrik; Grainger, David; Pettersen, Jostein (Peer reviewed; Journal article, 2023)
      Emission reductions in power generation for offshore oil and gas activities are key in order to reach climate targets in regions with this industry. This study presents a review of both established and immature low carbon ...
    • Testing of tri-partite CO2 gas cooler prototype for domestic hot water and space heating 

      Tolstorebrov, Ignat; Zendehboudi, Alireza; Banasiak, Krzysztof; Köster, Lukas; Álvarez Pardiñas, Ángel; Hafner, Armin (Science et technique du froid;, Chapter, 2020)
      The aim of this study was to test a tri-partite gas cooler for CO2 heat pumps (5-13 kW). The proposed heat exchanger allowed the simultaneous and separate production of space heating and domestic hot water with an integrated ...
