The proposal is to install improved pollution control equipment on the Liquor Burner at Kwinana in order to reduce emissions.
The existing pollution control equipment on the Liquor Burner consists of a primary and secondary cyclone with water scrubbing. The proposed pollution control equipment consists of a primary cyclone, filter, wet scrubber and a regenerative thermal oxidiser (RTO). The stack height would also be increased. Alcoa predicts the proposed equipment will result in reductions of Volatile Organic Compound (VOC) emissions of between 81 and 98 per cent.
