A potline for production of aluminium typically comprise several hundred electrolytic pots with one or two large centralized gas treatment centers (GTCs) located in the middle of the courtyard. An average fluoride flow is distributed back to each pot due to the mixing of the process gases before entry to the large centralized GTC. However, since pots are behaving differently each with unique HF evolving dynamics, a different approach is explored with dedicated PIA modules where the adsorbed fluoride is recovered back to the same pot.
The PIA concept integrates with the pot controllers to optimize the feed of alumina by demand into the gas adsorption reactors. The PIA concept also includes a high degree of prefabrication into container sized modules that are designed to be suspended directly from the pot room columns.
