| Abstract Scope |
The gasses generated at electrolytic cells (or pots) of aluminium smelters are drafted to a scrubber not only to keep overall emissions below regulation limits but also to control pot thermal balance and protect workers for being exposed to the pollutants from the pots.
Whilst most of the smelters have a constant flow being drafted from the pots, some plants include a "high draft" ventilation mode which allows a boosted draft that enhances gas collection when maintenance is performed at the pots.
This paper summarizes the possible designs for "high draft" ventilation and explains the effect on pot flows. |
