Pulp and automation system for the Oulo mill

At its Oulo mill in Finland, Stora Enso is having a bleached chemi-thermo mechanical pulp (BCTMP), evaporation and non-condensable gas (NCG) technology installed by Valmet.

Valmet will also deliver an extensive automation package as part of the project to convert the mill to produce consumer board in high-volumes.

The deliveries will carried out in phases and the upgraded mill is scheduled to be in operation in early 2025.

Sami Riekkola, pulp and energy business line manager at Valmet, said: “With Valmet’s process technology and automation, we enable Stora

Enso to produce carton board with excellent environmental performance and optimised fiber properties. Our leading BCTMP technology is built on Valmet’s strong ‘Fiber to Board’ knowledge. With the extensive automation package, we are able to offer Stora Enso a good visibility to the mill processes and excellent operability to maximize the performance of the whole mill.”

In addition, Valmet had already earlier agreed on a recovery boiler rebuild delivery for the Oulu site. The rebuild includes an electrostatic precipitator upgrade to ensure the required capacity for future production.
