Valmet will deliver a white liquor handling system to BillerudKorsnäs's pulp mill in Skärblacka, Sweden. The start-up of the rebuilt plant is planned in June 2016.
The order is included in Valmet's second quarter 2015 orders received and the value of the order will not be disclosed.
"Previously Valmet has delivered a recovery boiler rebuild and a new evaporation plant to the Skärblacka mill. This upgrade will enable a production capacity increase, as existing equipment has become too small and is in a need of extensive maintenance," says Thomas Malmqvist, Sales Manager Pulp and Energy, from Valmet.
The new equipment that Valmet will install are a white liquor filter of type PDW and a causticizer tank. The white liquor filter produces a clear white liquor which increases the efficiency and availability in the pulping process. The separation of white liquor from lime mud is done by pressure filtration. After the rebuild the white liquor plant will have a capacity of 5 200 m3 per day.
BillerudKorsnäs' Skärblacka mill develops and produces everything from highly porous sack paper to fluting and white machine glazed kraft paper. Production capacity of the mill is 430 000 tonnes/year.
