The ALUMAR Refinery was designed to maximize heat recovery, and therefore minimize process steam requirements. Since the increase of alumina production from 0.5 to 1.2 million tons per year, the heat exchangers became a strategic point in the refinery performance. An objective has been to create a tool to improve the performance of the heaters.
A new application of technology by Alcoa in Kwinana, Western Australia, will save millions of dollars in residue area expansion, reduce the amount of land required to store residue and save more than one gigalitre of water annually by filtering bauxite residue created during the refining process so that more residue can be stored in less space.
