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 ... -
Characterization of industrial hydrocarbon samples from anode baking furnace off-gas treatment facility
Arnesen, Kamilla; Albinet, Alexandre; Chatellier, Claudine; Huynh, Nina; Aarhaug, Thor Anders; Einarsrud, Kristian Etienne; Tranell, Maria Gabriella (Peer reviewed; Journal article, 2023)Polycyclic aromatic hydrocarbons (PAHs) are naturally present in raw materials used as a binder in prebaked anodes for electrolysis of aluminum. Green anodes are baked to about 1200 °C through a cycle of 14–17 days where ... -
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 ... -
Morphology and Activity of Electrolytic Silver Catalyst for Partial Oxidation of Methanol to Formaldehyde Under Different Exposures and Oxidation Reactions
Lervold, Stine; Arnesen, Kamilla; Beck, Nikolas; Lødeng, Rune; Yang, Jia; Bingen, Kristin; Skjelstad, Johan; Venvik, Hilde Johnsen (Journal article; Peer reviewed, 2019)Electrolytic silver particles were studied in relation to its morphology changes under different reactive and non-reactive atmospheres, and its catalytic activity in oxidation of methanol to formaldehyde (MTF), carbon ... -
Oxidation of methanol to formaldehyde over Ag catalyst - A study of reaction pathways and Ag catalyst restructuring during MTF
Arnesen, Kamilla (Master thesis, 2018)Formaldehyde is recognised as an important industrial chemical, being a versatile organic molecule. Due to high reactivity, it is used as a building block to synthesise other chemicals and industrial products. Production ... -
PAH emissions from the metallurgical industry
Arnesen, Kamilla (Doctoral theses at NTNU;2023:269, Doctoral thesis, 2023)Polycyclic aromatic hydrocarbons (PAHs) are a large group of organic molecules consisting of two or more fused aromatic rings. They can be created by incomplete combustion of organic materials and accumulate in nature. As ...
