7. 10. The link between kraft cooking and bleaching : influence on ECF bleachabiblity and bleaching effluent parameters

   Author : Magnus Björklund; []
   Keywords : ;

   Abstract : The link between kraft cooking and bleaching was investigated, with the focus on how cooking kappa number, cooking conditions and pre-bleaching stages influence ECF bleachability and environmental parameters in the bleaching effluent. In one part of the study standard cooking conditions were used to produce birch and spruce pulps of different kappa numbers and then we studied how the AOX in the ECF bleaching effluent was affected by oxygen delignification, and hot acid stages.
