ODOUR EMISSION REDUCTION CASE STUDY AT ALCOA’S WAGERUP ALUMINA REFINERY

Cox S.J.

Alcoa World Alumina Australia’s Wagerup Alumina Refinery is located 130 km south of Perth in Western Australia. The refinery has received a high degree of community, government and media focus on emissions, particularly odours, since the installation of a liquor burning process in 1996. Significant reductions have been made to the refinery’s odour emissions since 1997 and by July 2002 we will have achieved a source odour reduction of approximately 50% at a cost of over $40M. This paper is an overview of the technical program to measure, identify and reduce odour emissions from the Wagerup Alumina Refinery.
