White liquor oxidation system
The purpose of white liquor oxidation is to improve the Na/S balance of the Kraft process by replacing make-up caustic with internally generated alkali. Valmet offers two well-proven and efficient alternatives, an air-based oxidation system for the production of partially oxidized white liquor for oxygen delignification and an oxygen-based system for the production of fully oxidized white liquor for bleaching and oxygen delignification. Oxidized white liquor can also be applied for many gas scrubbing applications.
