A study of anode baking gas composition
Aarhaug, Thor Anders; Brandvik, Trond; Kjos, Ole Sigmund; Gaertner, Heiko; Ratvik, Arne Petter (Journal article; Peer reviewed, 2018)A method has been developed to measure gas composition inside the pit in open anode baking furnaces. The gas composition can be used to understand attack on and degradation of the refractory lining, baking behavior and ... -
Online monitoring of aluminium primary production gas composition by use of Fourier-transform infrared spectroscopy
Aarhaug, Thor Anders; Ferber, Alain Marc C; Kjos, Ole Sigmund; Gaertner, Heiko (Journal article; Peer reviewed, 2014)Online monitoring of aluminium primary production raw gas is challenging due to the high concentration of HF in the presence of water. Tunable Diode Laser (TDL) analyzers retrofitted with sapphire optical windows allow for ...
