Abstract

The focus on fast pyrolysis research in Finland has been on fuel oil production from biomass for HFO-replacement applications. Experience has been gained by producing bio-oil from various feedstocks in bench and PDU scale units at VTT and lately in an integrated pilot scale unit Metso’s R&D facility in Tampere, Finland. Characterisation methods and fuel oil analyses have been developed, various bio-oils analysed, and compared, and work has been done in order to obtain specifications and standards for this new type of bio-oil. The consortium, Metso, Fortum, UPM, and VTT, has been operating a 7 tpd bio-oil production unit In Tampere in which a pyrolysis reactor is integrated to a conventional fluidized-bed boiler. The concept enables high overall efficiency and high bio-oil yields. All by-product streams are utilized to produce heat and electricity. Proof-of-concept has been carried out: over 100 tons of bio-oil has been produced and about 40 tonnes of bio-oil combusted in 1.5 MW district heating plant with high efficiency and low emissions. Metso is currently building a 30 MW bio-oil demonstration unit at the existing Fortum combined heat and power (CHP) plant in Joensuu, Finland. The start-up for an integrated unit is scheduled for late 2013. Process optimization and quality control through the whole value-chain is critical when moving to commercial scale systems. The focus of this paper is to discuss both on the challenges and the potential solutions for Fortum’s bio-oil demonstration plant.
