Visy Tumut exceeds targets by optimizing causticization
Feb 21, 2020
Visy’s kraft mill in Tumut wants to optimize the asset performance, increase production, and ensure process competitiveness with the latest technology. With causticizing optimization, their expectations and return on investment (ROI) targets have been exceeded.
After a few months’ use of Valmet APC with Valmet Recovery Liquor Analyzer, the results exceeded our targets. Overliming has been eliminated, TTA control has improved significantly, lime kiln is more stable, digester uses less white liquor/steam and production capacity increases.
