Evaporation optimization increases efficiency at SCA Obbola
SCA Obbola produces packaging paper and transport packaging, largely based on fresh wood fiber. The mill has implemented the Valmet Evaporation Optimizer to increase the efficiency of the evaporation process and to generate energy savings while keeping the burning liquor dry solids high and stable.
|Solution||Valmet Evaporation Optimizer, an advanced process control (APC) application|
Evaporation efficiency improved by up to 8,7% resulting in a significant reduction in steam consumption.
Burning liquor dry solids deviation was cut by 50%, stabilizing the operation of the evaporation plant and recovery boiler processes.
