Valmet to deliver new evaporation plant to Södra Cell Mönsterås pulp mill in Sweden


Valmet will deliver a new evaporation line 3 for Södra Cell Mönsterås pulp mill in Sweden. The new line will replace the oldest evaporation line 1 at the mill. The new evaporation plant is scheduled to start-up in the first quarter of 2023.

The value of the order will not be disclosed. However, a project of this size and scope is typically valued at around EUR 30 million. The order is included in Valmet’s orders received of the second quarter 2021.

“Our existing evaporation line 1 is over 40 years old and due to high recurring maintenance costs it now needs to be replaced with a new modern evaporation plant representing the state-of-the-art technology, which is more energy efficient and increases our mill’s performance. In hard competition Valmet presented the best overall solution for us and we are looking forward to this cooperation,” says Jonas Olander, Project Leader at Södra Cell Mönsterås.

“We have a long cooperation with Södra Cell and the Mönsterås mill’s evaporation plant. We tailored this new line to meet the customer needs for reliability and efficiency. The new line will increase the evaporation capacity and further improve the mill’s steam economy and energy efficiency by producing high dry solids for the recovery boiler. The water efficiency of the mill is improved by providing clean condensate for reuse at the mill,” says Fredrik Kall, Director, Evaporation, Ash & Bio Technology, Pulp and Energy, Valmet.

The new evaporation line 3 will have a capacity of 530 tonnes evaporated water per hour. The 7-effect line will feature Valmet Tubel technology for highest energy efficiency, availability and easy washing. The evaporation line will produce clean condensates for reuse in the mill processes. The line includes preparedness for lignin extraction with LignoBoost technology. Valmet’s delivery also includes inspection of the existing evaporation line 2.
