Södra Cell’s Mönsterås pulp and paper mill in Sweden has ordered a Valmet (Finland) recovery boiler upgrade and an evaporation line upgrade. The delivery is scheduled for the fall of 2016. 

The value of the order was not disclosed, but Valmet noted that the value of an upgrade of this scope is usually valued below EUR 6 million. 

 

"Recovery boilers need consistent upgrades at regular intervals. This kind of upgrade needs to be done due to the erosion and corrosion of the recovery boiler tubes based on third party inspection evaluation findings. We have been a trusted services partner for this replacement work with Södra Cell Mönsterås for several years and we are happy to continue good co-operation with them," said Marcus Grundevik, sales and project manager from Valmet.

 

 

Valmet's delivery includes replacement of several recovery boiler and evaporation line parts and additionally a new concentrated non-condensable gases (CNCG) burner system. 

As part of this upgrade the evaporation line 2 will be equipped with new Valmet TUBEL heating surface area in one of the effects. In a Valmet TUBEL Concentrator, liquor is evaporated on the outside of the tubes for easy on-line washing and to avoid chemical or mechanical off-line washing.

Södra is Sweden's largest forest-owner association, with more than 50,000 forest owners as its members. Södra is also an international forest industry Group, with operations based on processing its members' forest products.
