DualC™ Cooking for Paper Grade
The DUALC™ cooking process is based on a combination of advantages from SuperBatch® and RDH™ displacement cooking technologies.
The displacement batch cooking technique gives the best opportunities for optimal conditions and flexibility in cooking. In paper grades, 95-100% pulp strength delivery can be achieved. One key difference compared to other technologies is the two-stage black liquor pre-treatment before the cooking phase.
