   Sammanfattning : Various process streams in the pulp and/or paper mill contain valuable substances which can be converted into new products, e.g. lignin and xylane. LÄS MER

3. 22. Analysing strategic energy-related investments in process industries : applied studies at a pulp and board mill

   Författare :Magnus Karlsson; Lars J. Nilsson; Linköpings universitet; []
   Nyckelord :MIND; Industrial energy systems; Investment; pulp and paper; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The potential to reduce energy demand in industrial applications is often substantiaL Since energy cost represents a considerable share of the value added in several categories of process industries, a great potential exists for cutting costs through investment, for instance in energy efficiency improvements. However, industrial energy systems form complex relations not only within the industrial unit, but also in the interaction with their surroundings. LÄS MER

4. 23. Energy systems analysis of Swedish pulp and paper industries from a regional cooperation perspective : Case study modeling and optimization

   Författare :Sofia Klugman; Bahram Moshfegh; Thore Berntsson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial energy system; Optimization; District heating; Energy audit; Co-operation; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The industrial sector uses about one third of the energy end-use in the world. Since energy use in many cases highly affects both the local and global environment negatively, it is of common interest to increase energy efficiency within industries. LÄS MER

5. 24. Biomass Gasification-Based Biorefineries in Pulp and Paper Mills – Greenhouse Gas Emission Implications and Economic Performance

   Författare :Johan Isaksson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biorefinery; heat integration; energy efficiency; CO2 emissions; process integration; pulp and paper mill; biomass gasification;

   Sammanfattning : The pulp and paper industry has a great opportunity to take advantage of the experience about forestry and wood handling for production of renewable fuels, chemicals and materials. Residues from forestry, i.e., tops, branches and stubs, have great potential to become a raw material that can replace crude oil or natural gas in many applications. LÄS MER

7. 25. Dusting in a lime kiln - Characterization of the material and unit operations

   Författare :Henric C O Dernegård; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; terminal velocity; Dusting lime kiln; fines; lime mud filter; ESP-dust; reactivity;

   Sammanfattning : The present thesis describes the background of, and gives some points of orientation for, the phenomenon of dusting in the burner zone of a lime kiln. The aim of this study is twofold: to increase knowledge of the factors that influence the degree of dusting and also to investigate the effect a dusting lime kiln has on the white liquor preparation process.
