  1. Production of Chemicals and Materials in Future Pulp Mill Biorefineries Karin Lindgren, Innventia

  2. INNVENTIA AB • Staff 270 • Swedish R&D company • Serving customers globally • Pulp, paper, packaging, printing, new materials and biorefining Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  3. Chemical pulping process Source: Aker Kvaerner

  4. Biorefinery – Simultaneous production of fibres, energy and chemicals • Increasing costs • Energy and wood • Decreasing trend prices on pulp • Biorefinery is the solution • Handling of large volumes of biomass • New pulp mill products • New efficient separation processes • Add “side” processes • Innventia approach • Kraft/soda pulp mill platform • Focus on the major components • Efficient separation process and mill integration Lignin carbon fibres Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  5. Cellulose

  6. Wood/plants- a mine for valuable polymersCellulose Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  7. Cellulose Products NanoCellulose Kraft Pulp Fibres Fibre PLA Composite Transparent Films Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  8. Lignin from black liquor - LignoBoost

  9. 50% of the wood ends up in cooking liquor Cellulose products Pulp Wood to kraft pulp mill Carbohydrates Black liquor Extractives Lignin 55-60 % of energy goes into the black liquor Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  10. Wood/plants – a mine for valuable polymers- lignin Physical/chemical properties vary with species and process Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  11. The LignoBoost process Lignin IN Replacement of fossil fuel in lime kilns 50 L fuel oil ptp can be saved Lignin OUT Recovery Boiler Evaporation Lime Kiln Digester Wood Wood Chips Bleaching Pulp/Paper Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  12. The LignoBoost process Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  13. LignoBoost lignin – a new material Typical composition, % C 64 - 66 Na 0.05 - 0.4 Ash 0.3 - 1 S 1 - 3 N 0.1 Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  14. Metso filter in Innventias lignin demo plant VPA 1040 24 chambers 1-1.2 t lignin/h Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  15. Fossil fuel in pulpmill lime kilns In Sweden ca 300.000 tonneoil/year Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  16. Carbonfibres - High valueapplication of lignin • Construction material in composites • Light Weight • High Strength and Modulus • High Resistans to Heat and Corrosion Expensive Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries

  17. Oil or renewable Karin Lindgren, Production of Chemicals and Materials in Future Pulp Mill Biorefineries
