Process Integration of various biorefinery concepts with a mechanical pulping – papermaking mill
Start of project 2010-05-01
End of project 2013-07-31
Norske Skog has embarked on a program to investigate biorefinery technologies that will influence the manufacturing process of mechanical pulping- papermaking of today. Norske Skog is part of an intensive wood-based industry, and has the logistics needed for harvesting more wood and help to achieve the national target to increase the production of bio-energy with 14 TWh and 18 TWh of renewable energy within 2020.
The PROFIT-project aims at developing technical solutions for profitable bioenergy production and more profitable paper production by integrating a synthetic biodiesel plant and/or a pellet plant at the Norske Skog Follum paper mill, Hønefoss (Norway).
1. Raw materials logistics
2. Improved paper production
3. Bioenergy production & Process Integration.
The development of an innovative raw material logistics and handling system shall provide less costly, low-quality wood raw material for pellets and/or synthetic biofuel production.
For the paper producer, improved raw material handling system shall ensure improved Thermo Mechanical Pulp (TMP) quality for newsprint and book paper production.
Energy densification pretreatment techniques like torrefaction and fast pyrolysis will be addressed. Heat integration and use of waste energy from the paper mill will form the basis for an energy efficient pellet and/or synthetic biodiesel production.
The major process systems involved are the Paper Mill, Multi-fuel boiler, Biomass-to-Liquid Plant and Pellets Plant.
In addition to the four mentioned process systems, we also have to look into: District Heating, Turbines, Waste Combined Heat & Power.
The four (4) milestones for this section of the project are:
The energy saving potential for biofuel production from wet biomass by utilizing waste heat and by heat integration with paper mill and a waste combustion plant elucidated (Follum as case mill).
The profitability of a district heating system at Hønefoss evaluated.
Techno-economical evaluation of integrating raw material handling and heat handling system in a paper mill, waste combustion plant, pellet plant and a liquid biofuel plant elucidated.
Advantages and challenges by integrating paper production, pellets production, waste combustion, and liquid biofuel production mapped from all producer's point of view.
As part of the techno-economical analysis, a asenarios assessments will be based on “energy market scenarios”, which will includes the ENPAC and reMIND methods, developed by Chalmers University.
Based on these assessments, it will be easier to draw clearer conclusions and find reliable robust investment alternatives.
The project will be finished 1st of July 2013. For more information: www.re-cube.net
