Valmet to deliver a new white liquor filter to Rottneros Vallvik pulp mill in Sweden

Valmet Corporation's trade press release on April 6,2016 at 12:00 p.m. EET

Valmet will deliver a white liquor filter to Rottneros Vallvik pulp mill located on the east coast of Sweden. White liquor filter is part of the pulp mill's chemical recovery process. 

This investment is part of Rottneros AB's larger rebuild project called Agenda 500, which aims to increase availability and the total production volume at both of Rottneros AB's pulp mills, Rottneros Mill and Vallvik Mill, and with a target to reach a capacity of 500,000 tons per year.

The new white liquor filter will replace an existing filter delivered by Valmet in 1990. A larger filter is needed to handle the capacity increase at the mill. Start-up of the new filter is scheduled for autumn 2016.

The order is included in Valmet's first quarter 2016 orders received. The value of the order will not be disclosed. A white liquor filter is usually valued below EUR 5 million.

"Vallvik has great confidence in Valmet as a supplier and despite a very tough schedule, we have a good reason to assume that Valmet will deliver on time. In addition, I personally look forward to working with Valmet again because this is my third project with Valmet regarding installation of pressurized disc filter," says Per-Arne Nilsson, Project Manager at Vallvik mill.

"Despite being a trusted partner with Vallvik for more than 40 years in the white liquor area, the tight schedule of this project was a challenge when pursuing this project. All people involved in the sales phase participated in the strategic and proactive work to compress the delivery time, and they deserve big thanks for their efforts. We are very pleased and look forward to a good and safe project implementation phase," says Thomas Malmqvist, Sales Manager at Valmet.

Valmet will also deliver a new bleach plant to Rottneros pulp mill, which was published earlier this year.

Technical details about the delivery

Valmet's delivery includes a new PDW-type white liquor filter, erection, start-up services, basic engineering for piping, for instrument and for electrical and process control. The PDW pressure disc filter produces completely clear white liquor and washes the lime mud. The very high white liquor yield increases upstream capacity and eliminates the potential process disturbances that increased amount of dregs and other non-process elements (NPE's) in the white liquor can cause.
