Today, in the electrolysis area of modern aluminium smelters, pot gas emissions are very efficiently treated by the latest generation of dry scrubbing technologies such as Ozeos, with rates close to 99.8%. As a consequence, stack emissions only represent a very small amount of the total Fluorides emitted over the entire smelter. Indeed, most of the HF is released to the atmosphere directly from the potroom, where in many smelters no specific treatment is provided to limit emissions related to maintenance activities (pot hoods opening, spent anodes removal, etc.). Fives now proposes a solution to eliminate emissions coming from hot spent anodes stored in potroom thanks to an Anode Inert Tray (AIT) which confines butts. This paper presents the performances of the industrial first of class AIT developed conjointly between Fives Solios and Fives ECL and which has been operated by ALRO for several months.
