Presentation Transcript

  1. Biomass-Conversion: • Energy production (power, heat, biofuel) and additional products (chemicals, new materials) in the future biorefinery • Energy reduction in the pulp and paper processes Paper and Fibre Research Institute (PFI) 26.05.2011

  2. PFI Paper and Fibre Research Institute AS • Independent research institute in Trondheim, Norway • R&D with focus on processes/products based on lignocellulosic materials. • Focus areas: • Wood fibres • Pulp and paper • Novel biobased materials (composites, MFC) • Biofuel/bioenergy/biorefinery • Characterization of fibre structures and products • Subsidiary of INNVENTIA AB since 2004

  3. Focus area Biofuel/biorefinery • Raw materials • Type (softwood, hardwood, straw, bagasse) and quality (waste, bark, mixed raw materials) • Pre-treatment and separation processes • Biochemical converting: • Mechanical, thermal, chemical, biological treatment for extraction and separation of sugar components, lignin and extractives from biomass. • Thermo-chemical converting • Torrefaction, pyrolysis for energy densification of biomass. • Conversion to energy products (bio-fuel, bio-oil, pellets) and green materials/chemicals. • Characterization • Chemical and morphological of raw materials, intermediate- and end products.

  4. Energy reduction in pulp and paper processes • Reduced electrical energy consumption: • Norske Skog consumed 7.7 TWh electricity during 2010 and most of this was used in the thermo-mechanical pulping process (TMP). • In the TMP process, fibres are separated and developed and at the same time steam is produced. About 50-60% of this steam can be used for drying the paper on the paper machine. • PFI has together with Norske Skog and Andritz developed a new process called ATMP (Advanced TMP) where at least 25% of the electrical energy consumption can be reduced. Implemented, the new technology would reduce the electrical consumption in Norske Skog with 2.0-2.5 TWh annually. • In the ATMP process, new process stages are introduced and chemicals are used to facilitate the fibre development. • Reduced heat consumption: • Drying of paper requires huge amounts of steam energy and through furnish engineering, the energy consumption suring drying of newsprint has been lowered by 7 %.
