Metso Process Optimizer control system to
SCA Ortviken, Sweden

Metso installation of a process optimization control system to SCA Ortviken’s new TMP Plus line in Sweden. The control system enables a 5-10% lower energy consumption.

The Metso Process Optimizer delivery includes optimization modules for the complete TMP line with adaptive interactions between screening and refining as well as main line and reject handling.

“We have evaluated several different systems for control and optimization of our new TMP Plus line. Our evaluation showed that the Metso Process Optimizer is the best solution for us”, says Anders Gannå, Process Engineer, SCA Ortviken. He continues: “Based on the results from our previous Metso Process Optimizer installations, we expect to save 5-10% in specific energy consumption and reduce fiber property variations by 50% by using this system.”

The SCA Ortviken paper mill produces newsprint and light-weight coated (LWC) paper. The total TMP capacity is more than 2,500 tonnes/day. Ortviken paper mill is part of SCA´s Forest Products business area.


Results at SCA Graphic, Ortviken
The objectives with the installation of the Metso Process Optimizer at SCA Ortviken were: less variations in pulp quality, increase throughput, decrease energyconsumption and having the possibility to control/optimize longfiber and shive content simultaneuously. Benefits obtained from installing the process optimizer on eight refiners and seven screening lines at SCA Ortviken.

Refining

• 50% reduction in freeness variation
• 10% production increase
• 5% less energy consumption.

Screening

• 50% reduction in freeness variation
• 10% reduction of shive content.

Other benefits

• The possibility of minimizing shives,
  and maximizing average fiber length
• Easy to establish the relative order between cost, quality and production
• The adaptive system always finds the
  best settings, for example after a
  segment change.
