The Karlsborg mill in Sweden is installing a Metso Kappa Q to replace two old kappa analyzers in its bleached softwood craft fiberline. With five sample points, pulp lignin content and brightness, as well as fiber properties and shive content measurements, the Metso analyzer technology will provide opportunities for improved process optimization and quality control.
"The selection of supplier and analyzer was entirely based on the analyzer’s performance and opportunities, as well as Metso’s well-known organization for service, spares and support,” states Peter Carlsson, project manager at the Billerud Karlsborg mill. Startup is expected to be completed during October 2011.
Unique Two-Point Calibration Method
The Metso Kappa Q utilizes patented sweep technology to measure kappa and brightness with a unique two-point calibration method. Fiber and shive analysis at an early stage of pulping helps the user to produce more uniform pulp, and provide more precise information for pulp grading and grade differentiation for various end-use purposes.
Pulp production at Karlsborg dates back to the start of the 20th century. Today Billerud Karlsborg is one of the largest businesses in the region (Norrbotten), producing 130,000 tons of sack and craft paper, as well as 170,000 tons of market pulp. The mill comprises a pulp line, a paper machine, a coating machine and a drying machine for market pulp. Karlsborg is one of the Europe´s leading suppliers of white sack paper. White craft paper and bleached long-fiber sulphate pulp for sale on the open market are also produced at Karlsborg.
