The technology supplied by ANDRITZ will substantially contribute towards reducing emissions further and result in environmentally friendly, high-quality pulp production. ANDRITZ’s scope of supply encompasses:
— Modernization of the brownstock washing process, including a new multi-stage DD-Washer with compact layout;
— A new oxygen delignification stage for optimizing the kappa level to achieve 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.
