Oct. 26, 2016 - Valmet said that a new high consistency bleaching system that it supplied to Rottneros pulp mill in Sweden started up according to plan on September 19, 2016.

The start-up was smooth and the 48-hour test run was approved, Valmet added.

According to Valmet, the bleaching system was the first step in a larger rebuild project, called Agenda 500, at the mill. The long term goal is to increase both availability and the total production volume of Rottneros two pulp mills to reach a capacity of 500,000 tons per year.

"The check-out and start-up of the plant went beyond expectation, as you want it to do, and we have already been able to lower the peroxide charge. We are very satisfied with the equipment we have bought and it looks promising for the future. We will now continue to ramp up production," said Jan Viper, Project Manager at Rottneros mill.

Lars-Olof Larsson, Project Manager at Valmet, noted, “This has been a great project, well organized by Rottneros. Having all instruments and surrounding connections prepared made a fast start-up possible. Commissioning took only three days. When we started the project, the time table was very tight, but in the end we were actually ahead of schedule. This is the first installation of the FKC screw presses in Europe, so this is a good reference case for us.”

Rottneros produces market pulp and has an annual production capacity of just under 350,000 tonnes of pulp, produced at two mills in Sweden.
