    • Analysis of nitro- and oxy-PAH emissions from a pilot scale silicon process with flue gas recirculation 

      Arnesen, Kamilla; Andersen, Vegar; Jakovljevic, Katarina; Enge, Ellen Katrin; Gaertner, Heiko; Aarhaug, Thor Anders; Einarsrud, Kristian Etienne; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2023)

    • Flue Gas Recirculation for the Silicon Process 

      Andersen, Vegar (Doctoral theses at NTNU;2023:135, Doctoral thesis, 2023)
      Metallurgical-grade silicon is a critical material for modern society. It is used as an alloying agent in aluminium alloys, feedstock for silicones, photovoltaics and electronics. Silicon is produced by carbothermal reduction ...

    • Fuktskader i tilknytning til terrassedører 

      Andersen, Vegar (Master thesis, 2020)
      Undersøkelser av byggskader i Norge viser at ca. 66 % av alle prosessforårsakede byggskader opptrer i tilknytning til bygningens klimaskjerm. Med et klima som forandrer seg og bygg som blir utsatt for sterkere påkjenninger, ...

    • Pilot-Scale Test of Flue Gas Recirculation for The Silicon Process 

      Andersen, Vegar; Solheim, Ingeborg; Gaertner, Heiko; Sægrov-Sorte, Bendik; Einarsrud, Kristian Etienne; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2022)
      Flue gas recirculation (FGR) for the silicon process may facilitate increasing the CO2 concentration in the off-gas, which will be beneficial for potential future carbon capture. Lower oxygen concentration in the combustion ...

    • Scaling in the Si Off-gas Systems - The Effect of Alkali Content 

      Hauge, Erlend Gustav Rikardsen (Master thesis, 2022)
      Hensikten med denne masteren har vært å undersøke komposisjonen av avsetningen som finnes i pipen på silisiums og ferrosilisiums verk. Resultatet vil kunne brukes til å oppnå en bedre forståelse av hvilke faktorer som ...

    • Silica Fume Formation in Different Gas Atmospheres 

      Andersen, Vegar; Rasouli, Azam; Einarsrud, Kristian Etienne; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2023)
      Silica fume is an important byproduct from the silicon production process, with mainly concrete and refractory applications. In this work, the effect of different combustion gas atmospheres on the properties of silica fume ...

    • Tapping Gas from the Silicon Submerged Arc Furnace: An Industrial Measurement Campaign 

      Andersen, Vegar; Gaertner, Heiko; Grådahl, Svend; Ksiazek, Michal Tomasz; Einarsrud, Kristian Etienne; Tranell, Gabriella (Journal article; Peer reviewed, 2022)
      Producing high-silicon alloys in submerged arc furnaces (SAF) involves the generation of an intermediate process gas, consisting of silicon monoxide (SiO) and carbon monoxide (CO). Combustion of process gas from the taphole ...
