Papir- og fiberinstituttet AS Paper and Fibre Research Institute Paper and Fibre Research Institute (PFI) 26.05.2011 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
Papir- og fiberinstituttet AS Paper and Fibre Research Institute 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
Papir- og fiberinstituttet AS Paper and Fibre Research Institute 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.
Papir- og fiberinstituttet AS Paper and Fibre Research Institute 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 %.
