Abstract Scope Primary aluminum industry is facing the modern challenge of improving environmental footprint while increasing at the same time the overall metal production. Part of this challenge can be overcome by developing a good knowledge of technologies to optimize their performances. In that context, testwork was conducted in 2017 and 2018 on the Gas Treatment Center installed at the Rio Tinto AP60 Technology Center located in Canada. The AP60 GTC was originally supplied with standard filter bags except for one filtration module equipped with extended surface filter bags. This was part of the R&D vocation of the smelter. Back in 2017, the original bags were approaching the end of their useful life. The purpose of the testwork was to acquire a deep understanding about control of process parameters to optimize the GTC performances if ESB filters would be installed in all filtration modules. In this paper the testwork results are discussed.
