Black Liquor Fractionation for Production of Green Fuels and Chemicals

The project aims at fractionating the black liquor into its three components and thereafter converting the organic fractions into green fuels and chemicals.

The objectives are to evaluate the techno-economic feasibility of black liquor fractionation process and investigate how potential end-products could replace competing products from a sustainability perspective.

Optimal localisation of second generation biofuel production in Sweden

This project aims to develop a location optimisation model and to use it to determine and investigate optimal locations in Sweden for production of second generation biofuels, for different biofuel targets and under different boundary conditions. Examples of research questions are addressed :
Which locations are most suited for second generation biofuel production plants in Sweden? What type/s of biofuel should be produced and in which quantities?
How do various boundary conditions affect optimal production plant locations and production characteristics, and which parameters have the largest impact?

Increased energy efficiency and carbon dioxide reduction in steel mills

– Methanol from steel work off-gases
The main objective is to evaluate the techno-economic feasibility of the production of methanol at the SSAB steel mill in Luleå. Four methanol production cases are studied:
The excess coke oven gas only (650 GWh per year)
The excess coke oven gas mixed with biomass synthesis gas
The excess coke oven gas, basic oxygen furnace gas and biomass synthesis gas
Hydrogen (extracted from the COG via Pressure Swing Absorption) mixed with biomass based synthesis gas

Ökad tillgång till biomassa genom ökad effektivitet i virkestorkar

Projektet avser att frigöra stora mängder biobränsle (3-4 TWh) genom att effektivisera virkestorkar vid landets sågverk med bibehållen kvalite för torkgodset. Efterfrågan på biomassa har och kommer även framgent att öka, varför avsättningen av den extra energimängden svarar mot marknadens krav på en utökad tillgång på råvara. Eventuell användning av frigjord biomassa vid sågverket skall undersökas. Stigande energipriser leder till att sågverkens vilja att effektivisera processen ökar.
