The Hyper-Dense Phase System (HDPS) was developed in the mid-80’s by Aluminium Pechiney (AP) to provide its new centre-fed pots with an automatic and cost-effective alumina feeding system. This fluidized conveyor indeed ensures the most stringent technical requirements in terms of alumina quality and reliability are met. Over the years, it has thus contributed to AP Technology’s technical leadership, though it is no longer AP specific. But up to recently, it was limited to horizontal conveying, which, in some cases, restricted its potential applications. A major R&D program, which spanned over more than 10 years, was initiated to overcome this limitation and has led to the development of the patented HDPS siphon. The successful start-up of the siphons installed at the Rio Tinto Alcan (RTA) Kitimat smelter concluded this R&D phase. This paper will present this development work and the new potential of the HDPS system designed by RTA Alesa.
