  2. 1. Image-based quantitative infrared analysis and microparticle characterisation for pulp and paper applications

    Author : Kari Hyll; Lars Mattsson; Hannes Vomhoff; Samuel Schabel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metrology; stock; papermaking; refining; fibrillation; fines; filler; morphology; classification; flow microscopy; fibre analyser; flow cytometry; laser diffraction; dynamic image analysis; process variation; thermography; emittance; emissivity; infrared; MWIR; LWIR; goniometer; Production Engineering; Industriell produktion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Measurements of process variations and particle morphology are widely employed in the pulp and paper industry. Two techniques with high potential, infrared thermography and microparticle characterisation, are mainly used qualitatively. READ MORE

  4. 2. Breaking the chains : A technological and industrial transformation beyond papermaking: Technology management of incumbents

    Author : Michael Novotny; Staffan Laestadius; Lars Coenen; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Technological and industrial transformation; development block; incumbents; pulp and paper industries; wood-based biorefinery; diverging innovations of non-assembled products; Teknologisk och industriell omvandling; utvecklingsblock; etablerade företag och industrier; massa- och pappersindustrin; vedbaserade bioraffinaderier; divergerande innovationer av icke-sammansatta produkter.; Industriell ekonomi och organisation; Industrial Engineering and Management;

    Abstract : In recent years, the necessity and opportunity for transforming pulp and paper mills into integrative units for large-scale output of biochemicals, biomaterials, and biofuels have come up in discussions of industrial renewal in the Northern hemisphere (mainly in Canada, Sweden and Finland). This transformation is related to technology shifts as well as changing business models based on new bioproducts due to profoundly new market conditions. READ MORE

  5. 3. Pulp strength enhancement by oxygen delignification

    Author : Claudia Esteves; Elisabet Brännvall; Olena Sevastyanova; Sören Östlund; Christine Chirat; KTH; []

    Abstract : Oxygen delignification is widely used in the pulp and paper industry as a part of delignification process between the kraft cook and bleaching. However, its potential has not been fully utilized. READ MORE

  6. 4. Promises and Pitfalls of Bioenergy with Carbon Capture and Storage : Actors' Perspectives, Challenges, and Mitigation Deterrence in Sweden

    Author : Emily Rodriguez; Anders Hansson; Simon Haikola; Stefan Grönkvist; Nils Markusson; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Bioenergy with carbon capture and storage BECCS ; Negative emission technologies NETs ; Carbon dioxide removal CDR ; Sustainability transitions; Mitigation deterrence; Sweden; Bioenergi med koldioxidavskiljning och lagring bio-CCS ; Negativa utsläpp; Koldioxidinfångningsmetoder; Energiomställningen; Mitigation deterrence; Sverige;

    Abstract : Carbon dioxide removal (CDR) methods, such as bioenergy with carbon capture and storage (BECCS), have gained traction in international climate policy arenas to meet net-zero goals. Even though companies operating facilities with large point sources of biogenic emissions, such as pulp and paper industries and energy utilities, could implement carbon capture, there are few studies that take a bottomup perspective to study these key actors.
