Mats Nordlander, President, Paper of SCA says, ”The market’s most advanced kraftliner machine PM 2 with the best available technology will considerably improve the mill’s competitiveness, cost position and product quality. We see the partnership with Voith as the next step of our digitalized future.”
October 21, 2019
The new paper machine at the Obbola paper mill in Umeå, Sweden, will produce 725,000 tons of kraftliner per year. With a wire width of 10,200 mm and a design speed of 1,400 m/min, the PM 2 will be the most productive of its kind. The start-up of the machine is scheduled for the first quarter of 2023.
Taking full responsibility for the entire papermaking process and project handling
As full-line supplier for the entire papermaking process, Voith follows the Process Line Package (PLP) concept approach and assumes comprehensive responsibility for the project, covering the BlueLine stock preparation system and XcelLine paper machine. The comprehensive product scope includes detailed engineering and the supply of all sub-systems and components for the process line. The PLP reduces the number of required interfaces and contact persons and simplifies the entire project handling.
Highlights of the OCC plant include the IntensaPulper, the industry benchmark for energy efficient pulping, and the maintenance free InfiltraDiscfilter with BaglessPlus discs. The production line will enable industry benchmarks in kraftliner strength and convertibility to be achieved through a unique combination of proven components and intelligent controls. The multi-ply forming section with the DuoFormer Base and the MasterJet Pro headbox are tools for the online control of critical product quality criteria. The well-proven TripleNipcoFlex press section has been adapted for the production of kraftliner in order to achieve the highest production rates and surface quality levels. The CombiDuoRun dryer section, including EvoDry steel dryers and an intelligent S&C system, will ensure maximum runnability and energy efficiency. The VariFlex Performance winder incorporating SmoothRun technology will provide consistent quality rolls at maximum operational efficiency.
Long-term efficiency agreement
The long-term efficiency and service agreement will start right away. With digital applications on the existing PM 1 and a full-scale training program for the paper mill team supported by the Voith learning platform DRIVE as well as on-site services and trainings, a smooth start-up of PM 2 will be assured. The PM 2 will then be embedded in an extensive preventive maintenance program and efficiency optimization strategy for highest productivity of the production line.
“We know about the growing market for paper-based packaging. Our intention is to enable our customer to achieve excellent mechanical properties through a customized concept with intelligent controls,” states Christoph Mueller-Mederer, President, Projects EMEA at Voith. “The order from SCA means for us to provide the whole package consisting of safety, service, quality and efficiency partnership as well as to take full responsibility for the process line.”
Setting standards with digitalization and innovation
The scope of supply for SCA includes the biggest and most innovative package in Voith Paper history and sets a benchmark in digitalization. The Papermaking 4.0 technologies cover products of the OnEfficiency product family, which use machine learning to increase the efficiency of the plant. Furthermore, it stabilizes and improves product and process quality. The OnCare products – with monitoring applications as well as digital services like OnCall Video and the connectivity to the Voith Paper Webshop – complement the OnCumulus IIoT platform product portfolio and provide the foundation for a digital integration of the value chain and predictive maintenance. The new paper machine thereby benefits from the full digitalization scope.
