  1. 11. Process modelling in pulp and paper manufacture : Application studies with aspects of energy efficiency and product quality

    Författare :Daniel Ekbåge; Lars Nilsson; Helena Håkansson; Birgitta Engberg; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CTMP; freeness; process modelling; board machine; multiple effect evaporator; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : The manufacture of pulp and paper is an energy intensive process configured of several unit processes that shape a network of flows of wood chips, chemical pulp, mechanical pulp, board and other important components. Improved energy efficiency supports sustainability of the process and the products. LÄS MER

  3. 12. Sludge from pulp and paper mills for biogas production : Strategies to improve energy performance in wastewater treatment and sludge management

    Författare :Alina Hagelqvist; Thomas Nilsson; Karin M. Granström; Bengt Månsson; Bo Mattiasson; Thomas Welander; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anaerobic digestion; pulp and paper mill sludge; methane production; energy efficient sludge management; Miljö- och energisystem; Environmental and Energy Systems;

    Sammanfattning : The production of pulp and paper is associated with the generation of large quantities of wastewater that has to be purified to avoid severe pollution of the environment. Wastewater purification in pulp and paper mills combines sedimentation, biological treatment, chemical precipitation, flotation and anaerobic treatment, and the specific combination of techniques is determined by the local conditions.

  4. 13. Influence of Substrate Topography on Ink Distribution in Flexography

    Författare :Gustavo Gil Barros; Per-Åke Johansson; Gunnar Engström; Magnus Lestelius; Patrice J. Mangin; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paperboard; topography; optical measurement; OptiTopo; flexography; flexo; print quality; printability; uncovered area; UCA; image analysis; frequency analysis; surface properties; paper properties; test equipment; measuring instrument; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : The printability of paper in flexography is largely dependent on the topographical characteristics of the substrate. Topography imaging instruments make it possible to obtain three-dimensional scans of paper surfaces that can be further used to calculate valuable quality parameters. LÄS MER

  7. 15. Structure-Performance Relations of Oxygen Barriers for Food Packaging

    Författare :Åsa Nyflött; Magnus Lestelius; Ellen Moons; Lars Järnström; Carlsson Kvarnlöf Gunilla; Chris Bonnerup; José Maria Lagaron; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Barrier coating; Permeability; Dynamic Mass Transport; Modelling; Diffusion; Polymer; Dispersion; Kaolin; LCA; Starch; Hemicellulose; Materials Science; Materialvetenskap;

    Sammanfattning : Food packaging should ensure the safety and quality of food, minimize spoilage and provide an easy way of storing and handling it. Barrier coatings are generally used to meet the demands placed on fibre-based food packages, as these have the ability to regulate the amount of gases that can enter them. LÄS MER
