| Abstract Scope |
The presence of scale in process equipment during production of primary aluminium represents a factor that contributes to reduced performance. Formation of hard scale is best known in the oxide transport, operation of gas treatment units and heat exchangers. The maintenance cost of removing scale from process equipment may be significant. Studies have been carried out dealing with the formation of scale at various locations throughout the off-gas system from an electrolytic cell. Few specific hypothesis about factors leading to the formation exist. Sulfur seems to play a more important role than reported earlier. This publication covers 4 different scale types and their possible chemical formation pathways. |
