Enabling Efficient Heat Recovery from Aluminium Pot Gas
Clos, Daniel Perez; Andresen, Trond; Nekså, Petter; Johnsen, Sverre Gullikstad; Aune, Ragnhild Elizabeth (Chapter, 2017)In the present work, previous studies carried out by the Norwegian aluminium industry and research centres with the aim of recovering heat from aluminium production off-gas, are reviewed. The main challenge in improving ... -
Formation of Hard Grey Scale (HGS) on the Surface of a Cold-finger in the Aluminium Production Industry
Clos, Daniel Perez (Doctoral theses at NTNU;2021:183, Doctoral thesis, 2021)The present work has investigated the formation mechanisms of Hard Grey Scale (HGS) in a duct transporting the off-gas from aluminium production pot cells to the Gas Treatment Centre (GTC). For that purpose, a cooled fouling ... -
Investigation on scale formation in aluminium industry by means of a cold-finger
Clos, Daniel Perez; Nekså, Petter; Johnsen, Sverre Gullikstad; Aune, Ragnhild Elizabeth (Journal article; Peer reviewed, 2019)A cylindrical fouling probe or “cold-finger” has been used to investigate fouling from aluminium production off-gas. The probe was located upstream from the off-gas cleaning system. Surface deposits have been collected for ... -
Leaching and Modelling of LIB Black Mass (BM) for Metal Recovery
Olsen, Amalie My (Master thesis, 2022)På grunn av el-bilmarkedets eksponentielle vekst blir et stort antall Li-Ion-batterier (LIB-er) introdusert i samfunnet. Både essensielle råvarer og potensielt skadelige kjemikalier finnes i disse batteriene, og de etablerte ... -
Particle deposition characteristics in the formation of Hard Grey Scale (HGS) on cold surfaces exposed to aluminium production off-gas
Clos, Daniel Perez; Zedel, Hannes; Johnsen, Sverre Gullikstad; Nekså, Petter; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2021)Hard Grey Scale (HGS) is a hard and strongly adhering fouling material that forms on solid surfaces impinged by the off-gas generated in the pot cells of aluminium production plants. Different theories on HGS formation ...
