Valmet will supply an upgrade of the evaporation plant at Södra Cell's Mönsterås pulp mill in Sweden. The upgrade will unload the capacity of the existing evaporation line No. 1 and improve steam economy by increasing the capacity of the existing evaporation line No. 2. The delivery is scheduled for autumn 2016.
The evaporation plant concentrates black liquor coming from the digester in a mill. In the evaporation process, the evaporated water is brought back to the pulp production process to minimize mill's water consumption. After evaporation, the concentrated black liquor is fired in the recovery boiler for steam generation and recovery of cooking chemicals.
