Valmet will deliver a new flash drying and baling line and a rebuild of the existing integrated thermomechanical pulp (TMP) production line at SCA’s Ortviken mill into a chemi-thermomechanical pulp (CTMP) market pulp line, which will have a capacity of 300,000 tonnes per year. The delivery and installation of the equipment will take place during 2022 and the start-up of CTMP production is scheduled for the beginning of 2023.

The value of the order will not be disclosed. However, a project of this size and scope is typically valued at Euro 40-50 million.

The flash drying line includes two high consistency output TwinRoll presses for dewatering, Slab presses for bale forming and a baling line with a Wrapper applyer using paper as wrapping. Additionally, two identical flash dryers, developed with focus on energy efficiency, are part of the delivery including engineering, installation, training, start-up and commissioning.

Valmet and SCA have together developed a concept to produce CTMP at best possible operating expense using a combination of existing and new equipment. The unique chip treatment method, part of the HT-CTMP line currently used at SCA’s Östrand mill, will be utilized also in the rebuilt line at Ortviken.

SCA Ortviken in Sundsvall, Sweden, is a mill site in transformation. From having been one of the world’s largest publication paper mills, it will now become one of the world’s largest production lines for CTMP, using the parts of the infrastructure from the production of TMP and publication paper.

Valmet is the leading global developer and supplier of process technologies, automation and services for the pulp, paper and energy industries.
