According to a statement, the technology supplied will substantially contribute towards reducing emissions further and result in environmentally friendly, high-quality pulp production. Start-up is scheduled for the fourth quarter of 2019.

The scope of supply encompasses:

  • Modernization of the brownstock washing process, including a new multi-stage DD-Washer with the compact layout;
  • A new oxygen delignification stage for optimizing the kappa level to achieve the highest possible yield and minimum chemical consumption;
  • Relocation of the existing screening process after the oxygen delignification stage in order to minimize fiber losses;
  • Bleaching plant modernization by changing the existing 5-stage bleaching system to 4-stage bleaching;
  • Cooler for digester blow temperature control

Andritz has several hundred very successful DD-Washer installations as references around the globe. Andritz  DD-Washers are characterized by lowest operating costs and emissions as well as extremely good washing efficiency, based on the required number of displacement washing stages in a single unit.

The DD-Washer is also very gentle to fibers, retaining all the bulk, stiffness and strength of the pulp as there is no mechanical pressing during pulp washing.

Iggesund Paperboard produces paperboard for consumer packaging and graphics printing at one mill in Sweden and one in England. The company is a leading European producer of high-quality, virgin-fiber paperboard for use in the premium packaging and graphics sectors.
