||Continuous Optimization of the Energy Input – The Success Story of AOS

|On-Site Speaker (Planned)
During over 40 years of operation, engineers at Aluminium Oxid Stade GmbH (AOS) have acquired a lot of experience whereby they have developed a series of optimizations regarding the specific primary energy consumption. The tube digester technology, invented by VAW in Germany and applied on an industrial scale for the first time in Stade, was brought to perfection by its innovative cleaning methods, which led to a constantly high heat transfer, low pressure loss and excellent availability of the digesters. Further improvements such as the heat recovery from the exhaust gas stream of the salt heater as well as the optimization of one of the fluid bed calciners and the installation of a combined heat and power generator (CHP) led AOS to where it is now – a leading alumina refinery with regard to the lowest energy consumption per ton of alumina.
