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)Silicon alloys are produced by carbothermic reduction of quartz in a submerged arc furnace. This high-temperature pyrolytic process is a source of polycyclic aromatic hydrocarbons (PAHs), which are a group of aromatic ... -
Analysis of Polycyclic Aromatic Hydrocarbon Emissions from a Pilot Scale Silicon Process with Flue Gas Recirculation
Arnesen, Kamilla; Vachaparambil, Kurian Jomy; Vegar, Andersen; Panjwani, Balram; Jakovljevic, Katarina; Enge, Ellen Katrin; Gaertner, Heiko; Aarhaug, Thor Anders; Einarsrud, Kristian Etienne; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2023)Flue gas recirculation (FGR) is a method used in several industries to control emissions and process conditions, such as NOx reduction and temperature levels, and increase the CO2 concentration in the off-gas, to be better ... -
Atomic Layer Deposition of Titanium Oxide-Based Films for Semiconductor Applications—Effects of Precursor and Operating Conditions
Matkivskyi, Vladyslav; Leiviska, Oskari; Wenner, Sigurd; Liu, Hanchen; Vahanissi, Ville; Savin, Hele; Sabatino, Marisa Di; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2023)Two widely used atomic layer deposition precursors, Tetrakis (dimethylamido) titanium (TDMA-Ti) and titanium tetrachloride (TiCl4), were investigated for use in the deposition of TiOx-based thin films as a passivating ... -
Effect of (5%) CO2 on the Oxidation Rate During Cooling of Industrial Aluminum White Dross
Solem, Cathrine Kyung Won; Deledda, Stefano; Zedel, Hannes; Tranell, Maria Gabriella; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2023)Aluminum (Al) white dross is classified as hazardous waste and originates from the primary production of Al as a result of molten metal oxidation at an industrial scale. As the produced dross reduces the annual metallic ... -
Heavy Metal Emissions through Particulate Matter from Aluminium Electrolysis
Tranell, Maria Gabriella; Aarhaug, Thor Anders; Müller, Fride (Peer reviewed; Journal article, 2023)Heavy metal emissions from the aluminium industry are mainly carried from the plant through fugitive particulate matter (PM) originating from the aluminium electrolysis pot room. To evaluate the behaviour of metal-carrying ... -
Influence of Atmosphere and Temperature on Polycyclic Aromatic Hydrocarbon Emissions from Green Anode Paste Baking
Arnesen, Kamilla; Aarhaug, Thor Anders; Einarsrud, Kristian Etienne; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2023)Coal tar pitch, a well-known source of polycyclic aromatic hydrocarbons (PAHs), is used as a binder of petroleum coke in prebaked anodes used for electrolysis of aluminum. Anodes are baked up to 1100 °C over a 20-day period, ... -
Laboratory method for investigating the influence of industrial process conditions on the emission of polycyclic aromatic hydrocarbons from carbonaceous materials
Jakovljevic, Katarina; Aarhaug, Thor Anders; Gaertner, Heiko; Arnesen, Kamilla; Kero, Ida Teresia; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2024)This work is dedicated to developing a laboratory method for assessing emissions of polycyclic aromatic hydrocarbons (PAHs) from different carbon-based materials at elevated temperatures. The method will additionally ... -
