Valmet to supply brown stock washing plant modernization to Södra Cell's Mörrum pulp mill in Sweden

Valmet will supply a modernization of the brown stock washing plant of the dissolving line to Södra Cell's Mörrum pulp mill in Sweden. The rebuild is part of the second stage of a long-term initiative at Södra Cell Mörrum mill.


The brown stock washing plant rebuild will increase the mill's pulp production capacity by 45,000 tons. The project will commence in spring 2016 and is scheduled for completion in the fourth quarter of 2017.

The order is included in Valmet's second quarter 2016 orders received. The value of the order will not be disclosed. A rebuild with this scope is usually valued below EUR 10 million.

"The successful cooperation with Valmet on the dissolving line that began in 2011 continues with the next step. The investment will enable increased production and increased opportunities to further enhance the production quality of our dissolving pulp," says Martin Säll, Engineer and Project Manager at Södra Cell Mörrum.

During the strategy period 2014-2020, Södra Cell Mörrum will gradually offer larger volumes and expand production capacity from 380 000 tons to 500 000 tons of which 200 000 tons will consist of high quality dissolving pulp.

Technical details about the delivery

The modernization of the brown stock washing plant mainly contains the installation of three new Valmet TwinRoll presses, two before the oxygen stage and one before the bleach plant.

"The latest Valmet TwinRoll generation takes dewatering and washing to a new level by increasing capacity by up to 30 percent, improving consistency, and optimizing operation while minimizing operational and maintenance costs. Our TwinRoll presses have proven their functionality in several dissolving lines over the years. We are confident that this is a good solution for Mörrum mill and look forward to a great collaboration also in this project," says Mikael Gustafsson, Sales Manager at Valmet.
