Oxygen delignification systems pass 100 total

Kvaerner Pulping celebrates the total of 100 oxygen delignification systems with a contract award from Billerud AB Gruvön mill in Sweden for their birch fiberline

Billerud AB Gruvön mill in Sweden has awarded Kvaerner Pulping a contract for an oxygen delignification system.

The order is a milestone for Kvaerner Pulping since it marks the one-hundredth oxygen delignification system supplied by the company.

The new system at the Gruvön mill will be used in the birch fiberline and is part of a quality and environmental improvement programme at the mill.

Start-up is scheduled for November 2005.

"We make considerable investments in order to offer the most innovative technology to the pulping industry, and the area of oxygen delignification is a good example of that we fulfil this ambition," says Per-Åke Färnstrand, President at Kvaerner Pulping.

In collaboration with SAPPI and L'Air Liquide, Kvaerner Pulping (Kamyr) introduced the first commercial full-scale oxygen delignification system at SAPPI Enstra, South Africa, in 1970.

Since then the development has gone through medium consistency delignification and 2-reactor systems to Kvaerner Pulping's state-of-the-art DUALOX system.
