The Valmet Washing Optimizer adapts washing liquor flows to the production rate and capacities of washers for maximum washing efficiency.
2-4% - production increase through fewer evaporation bottlenecks
5-15% - less washing loss for higher chemical savings
2-5% - evaporation steam savings from higher dry solid content
Optimized washing efficiency improves cooking chemical removal from fibers during the washing process. With lower washing losses, the Valmet Washing Optimizer helps you avoid unnecessary use of bleaching chemicals.
The optimizer’s intelligent controls enhance the disturbance tolerance of the process. Better brown stock washing leads to less sodium loss and savings in both oxygen delignification and bleaching chemicals.
The Valmet Washing Optimizer also monitors rotation speed and prevents excessively low speed and disturbances. Improved washing efficiency reduces the need for washing filtrate, increasing your washing capacity. Fewer process stoppages positively impact capacity as well.
