Rottneros Mill Orders Valmet High Consistency Bleaching System

Valmet, Sweden, will supply a new high consistency bleaching system to Rottneros pulp mill in Sweden. This is the first step in a larger rebuild project, called Agenda 500, at the mill. The longtime goal is to increase both availability and the total production volume of Rottneros’ two pulp mills to reach a capacity of 500,000 metric tpy. 

Planned delivery time for the bleaching system is thios coming July. The value of the order was not disclosed, but according to Valmet, typically an order of this scale is valued at around EUR 2-4 million. 

"In our investment project we aim to increase capacity and lower our chemical consumption. We have had a long and good relation with Valmet over the years, which is one of the reasons for choosing them as supplier," said Nils Hauri, production manager at Rottneros mill.

"Valmet's bleaching system offers high availability with low operational cost, including energy and chemical consumption and maintenance costs. We are convinced that this bleaching system will live up to all expectations in this project," said Johan Eurenius, sales manager at Valmet.

Valmet's delivery includes machinery and erection, training, commissioning, and startup services. The new high consistency bleaching system consists of a chemical mixer and a bleaching tower, two washing stages with screw presses and MC pumps. The project is designed to lower peroxide consumption, increase capacity, and keep maintenance costs to a minimum.

Rottneros produces market pulp and has an annual production capacity of just under 350,000 metric tons of pulp, produced at two mills in Sweden. In 2014 Rottneros employed around 250 people, the majority in Sweden, and had sales of approximately SEK 1.5 billion.
