1. 1. The Impact of Dissolved Matter on Fiberline Processes

   Författare :Caroline Wilke; Ulf Germgård; Niclas Andersson; Juha Fiskari; Karlstads universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bleach plant control; Carbonate; Carryover; Chlorine dioxide bleaching; COD; Dissolved lignin; Dissolved matter; Fiberline control; Filtrate; Hexenuronic acid; Hydrogen peroxide bleaching; Kappa number; Oxygen delignification; Wash loss; Chemical Engineering; Kemiteknik;

   Sammanfattning : The impact of dissolved matter on the performance of four fiberline process stages was investigated: oxygen delignification, hot acid treatment, chlorine dioxide bleaching, and hydrogen peroxide reinforced alkaline extraction. In particular the impact on delignification due to dissolved lignin was studied. LÄS MER

3. 2. Studies on controllability of integrated process systems

   Författare :Hong Cui Carlemalm; KTH; []
   Nyckelord :;

   Sammanfattning : In response to stricter requirements on increased efficiencyand reduced environmental impact, production plants in theprocess industries are becoming tightly integrated withextensive recycling of material and energy. This thesisconsiders some consequences of such recycling for the dynamicbehavior of process systems. LÄS MER
