    • Gas cleaning with Granular Filters 

      Natvig, Ingunn Roald (Master thesis, 2007)
      The panel bed filter (PBF) is a granular filter patented by A. M. Squires in the late sixties. PBFs consist of louvers with stationary, granular beds. Dust is deposited in the top layers and on the bed surface when gas ...

    • Gas Compression Tool Validation 

      Strøm, Katrine Lie (Master thesis, 2011)
      A decline in field developments on the Norwegian Continental Shelf over the last years has led to an increase in tie-ins of smaller- and more stranded fields to the existing production facilities. This results in more ...

      Rakvåg, Adrian (Master thesis, 2022)
      The compressor laboratory at NTNU Valgrinda created in 2018, need some upgrades to properly function as a anti-surge compressor laboratory. The laboratory is being used by control students to learn how to tune controllers ...

    • Gas dechlorination of plastic pyrolysis derived oil with model compounds using Fe based materials. 

      Kjønli, Andrea (Master thesis, 2023)
      Verdens produksjon av plast har økt raskt siden 1950-tallet på grunn av dens utmerkede egenskaper. Dessverre blir bare en liten fraksjon av denne plasten resirkulert, noe som fører til massive mengder plastavfall som ...

    • Gas electrodes with nickel based current collectors for molten carbonate electrolyte thermo-electrochemical cells 

      Kandhasamy, Sathiyaraj; Haarberg, Geir Martin; Kjelstrup, Signe; Solheim, Asbjørn (Journal article; Peer reviewed, 2019)
      Thermo-electrochemical cells with inexpensive molten carbonate electrolyte and (CO2|O2) gas electrodes allow the possible conversion of high temperature waste heat from industrial processes into electricity. The cell ...

    • Gas Evolution in Li-ion Rechargeable Batteries: A Review on Operando Sensing Technologies, Gassing Mechanisms, and Emerging Trends 

      Zheng, Tianye; Muneeswara, Madithedu; Bao, Haihong; Huang, Jiaqiang; Zhang, Leiting; Hall, David Scott; Boles, Steven Tyler; Jin, Wei (Journal article; Peer reviewed, 2024)
      Gas evolution is fundamentally problematic in rechargeable batteries, and may lead to swelling, smoking, and device-level failure. In laboratories, monitoring gas evolution can help understand dynamic chemical events inside ...

    • Gas explosions in process pipes 

      Kristoffersen, Kjetil (Doktoravhandlinger ved NTNU, 1503-8181; 2004:79, Doctoral thesis, 2004)
      In this thesis, gas explosions inside pipes are considered. Laboratory experiments and numerical simulations are the basis of the thesis. The target of the work was to develop numerical models that could predict accidental ...

    • Gas Flotation for Subsea Produced Water Treatment - Development of a Method 

      Larsen, Robert André Gjelsten (Master thesis, 2022)
      I oljeutvinningsindustrien er produsert vann den største avfallsstrømmen målt i volum, og fraksjonene av vann til hydrokarboner som utvinnes fra oljebrønner har en tendens til å øke over tid. For å sikre riktig håndtering ...

    • Gas Flow and Pressure Drop in Charge Material in Silicon Production 

      Ringdalen, Eli; Einarsrud, Kristian Etienne; Nordhus, Astrid (Peer reviewed; Journal article, 2022)
      Gassing, outbursts of high-rate gas flows through the taphole, is a phenomenon that sometimes occurs during tapping of silicon furnaces. In addition to being an HSE challenge, this might also affect the tapping, while the ...

    • Gas Flow in Charges for Mn-Ferroalloy Production 

      Eidsaune, Tyri (Master thesis, 2023)
      Et sentralt mål for ferromanganindustrien er å redusere energiforbruk og utslipp av klimagasser knyttet til produksjonen. For å bidra til å løse disse utfordringene ble PreMa-prosjektet initiert. PreMa-prosjektets mål er ...

    • Gas flow through shallow sediments - A case study using passive and active seismic field data 

      Landrø, Martin; Wehner, Daniel; Vedvik, Noralf; Ringrose, Philip; Løhre, Nora Løw; Berteussen, Karl-Andreas (Journal article; Peer reviewed, 2019)
      Offshore Quaternary sediment sequences are generally weak and unconsolidated, and fluid flow through these rock formations is hard to predict or model. Surface flow observations, such as gas seeps, often appear random and ...
