Valmet to upgrade evaporators at Södra Cell, Mönsterås pulp mill in Sweden
Valmet Corporation's press release on June 16, 2015 at 11:00 a.m. EET
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 value of the order will not be disclosed. However, a project of this type and scope is typically valued at around EUR 10 million. The order is included in Valmet's second quarter 2015 orders received.
The new order follows a similar major evaporation plant upgrade of the Södra Cell, Värö mill, which was awarded to Valmet last year together with upgrades of most process areas in the same mill.
"We are looking forward to this project and are satisfied with the technical concept Valmet has offered us. This will improve the function of the evaporation plant, increase the energy efficiency and increase our profit," says Jonas Olander, Project Leader at Södra Cell Mönsterås.
"We see this evaporator upgrade bringing many benefits for Mönsterås mill. Besides improving the steam economy of the plant, we are implementing dry solids content control of the firing liquor to the recovery boiler. We will also add additional washing possibility of existing heating surface areas to improve plant availability. We are happy to continue our good co-operation with Södra Cell," says Fredrik Vedin, Product Sales Manager EVAPS at Valmet.
Details about the delivery
The evaporation plant in a mill concentrates black liquor coming from the digester. In the evaporation process the evaporated water is brought back to the pulp production process in order 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.
The new Valmet equipment to be installed will be two Tube Evaporators, a Falling Film Reflux Condenser and four liquor preheaters. A substantial upgrade of the piping system and an integration and upgrade of an existing condensate treatment system will also be performed.
Over the years Valmet has assisted Mönsterås mill by making several smaller and larger upgrades of the existing evaporators. The co-operation started in 2001 when Valmet replaced damaged lamellas with TUBEL and also installed a new TUBEL Super Concentrator.
