Composition and Structure Analysis of Hard Grey Scale (HGS) Formed on Cold Surfaces Exposed to Aluminium Production Off-gas

Perez Clos, Daniel; Zedel, Hannes; Johnsen, Sverre Gullikstad; Nekså, Petter; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2022)

Hard grey scale (HGS) is a strongly adhering fouling material forming on solid surfaces impinged by off-gas generated in the pot cells of primary aluminium production plants. Even though associated maintenance costs have ...
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 ...
