A Metso-supplied fine paper production line of the Portucel Soporcel group was successfully started up at the group’s Setúbal mill in Portugal on August 15, 2009. The 11.1-m-wide (wire) PM 4 will produce close to 500,000 tons of uncoated fine papers annually.
The delivery included a complete OptiConcept paper machine line from headbox to roll handling, with related air systems and some stock preparation equipment. Metso also supplied an extensive automation package, including a quality control system with web-wide non-scanning moisture measurement, wet end analyzers, machine controls as well as a runnability and condition monitoring system.
The new Setúbal PM 4 is the largest and most sophisticated paper machine in the world for the production of uncoated fine papers.
