Valmet Washing Line Optimizer
The Valmet Washing Line Optimizer application adapts washing liquor flows to the production rate and the capacities of the washers to result in desired washing efficiency. Optimized washing efficiency maximizes the cooking chemical removal from fibers during the washing process. Due to low washing losses unnecessary use of bleaching chemicals is avoided. The used fuzzy logic controls and soft sensors enhance the disturbance tolerance of the process.
