Valmet will deliver bleached chemi-thermo mechanical pulp (BCTMP), evaporation and non-condensable gas (NCG) technology as well as an extensive automation solutions package for Stora Enso’s Oulu mill in Finland. The delivery is part of Stora Enso’s approximately EuroUR 1 billion investment to convert the remaining idle paper machine at their Oulu site into a high-volume consumer board production line.
The value of the order will not be disclosed, but a delivery of this size and scope is typically valued at around Euro 75–100 million. The deliveries are done in phases and the upgraded mill is scheduled to be in operation in early 2025.
Valmet’s technology delivery includes a BCTMP line, an evaporation plant, and a NCG boiler for odorous gas handling. The BCTMP line has low operating costs, high process flexibility and reliability with excellent pulp quality and high bulk for board production. The evaporation plant is tailored for BCTMP filtrate recovery with high energy efficiency, and low electricity and steam consumption. It includes a Valmet Mechanical Vapor Recompression (MVR) Evaporator and the mechanically reliable Tube Evaporation technology. The NCG boiler is designed for very low NOx emissions. The delivery is supported by Valmet Industrial Internet solutions including connectivity and process support with analytics tools.
Valmet’s automation delivery includes a mill wide Valmet DNA distributed control system with the new web-based user interface as well as an integrated Valmet IQ Machine Vision system.
