Valmet to supply a white liquor pressure disc filter to Daio Paper Co. Ltd. in Japan
Valmet Oyj's trade press release on December 30, 2016 at 11:00 a.m. EET
Valmet will deliver a white liquor pressure disc filter to Daio Paper Co. Ltd's Mishima pulp mill in Japan. The new filter is scheduled to start-up in September, 2017.
The order was included in Valmet's third quarter 2016 orders received. The value of this kind of an order is typically less than EUR 5 million.
"Daio Paper planned for a new white liquor filter to be installed in parallel with the existing two lines of white liquor filters. This investment is done in order to be able to increase the white liquor production, which was limited in the existing lines. Daio selected the Valmet OptiDisc WL filter as the preferred technology for this de-bottlenecking project," says Jiro Nakamura, Product Sales Manager at Valmet.
Technical details about the delivery
White liquor filters are used at pulp mill's chemical recovery process to secure a consistent quality of the white liquor, with an optimal strength suitable for the plant. Modern digesters need a high and consistent quality of white liquor to produce the optimal pulp quality and yield in cooking.
Valmet's delivery includes a new OptiDisc WL filter, pumps piping, valves, platforms, erection and start-up services. The OptiDisc WL 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 in the pulp cooking process.
