DualC™ Cooking for Dissolving Grade
The DUALC™ cooking process is based on 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 dissolving grade, hemicelluloses are removed/adjusted in acidic conditions created by auto hydrolysis that comes from removal of acetyl groups of wood material. No additional chemical is needed for steam hydrolysis reactions.
