Dispersion and dissolution of alumina in cryolite melts: impact of sulfur and carbon on dissolution behavior in see through cell
Aulie, Vegard (Master thesis, 2021)Aluminium blir produsert industrielt ved hjelp av Hall-Herôult metoden. Denne metoden produserer flytende aluminium fra aluminiumoksid (kalt alumina) og karbon i ett bad med flytende kryolitt. Denne prosessen krever høy ... -
Dissolution Characteristics and Concentration Measurements of Alumina in Cryolite Melts
Bracamonte, Luis Carlos Izaguirre; Aulie, Vegard; Rosenkilde, Christian; Einarsrud, Kristian Etienne; Sandnes, Espen (Peer reviewed; Journal article, 2021)Alumina dissolution is one of the most important processes in the Hall-Héroult process. In this work, video recording using a high-speed camera and a see-through cell and electromotive force (emf) based alumina sensor ... -
On Gaseous Emissions During Alumina Feeding
Gylver, Sindre Engzelius; Follo, Åste Hegglid; Aulie, Vegard; Granlund, Helene Marie; Sørhuus, Anders; Sandnes, Espen; Einarsrud, Kristian Etienne (Peer reviewed; Journal article, 2021)Aluminium electrolysis involves feeding of alumina into a cryolite-based bath. Water originating from alumina as well as from air reacts with fluorides and results in HF evolution. Untreated HF gas is a significant ...
