Pyrolysis reactor

Product storage

The PO liquid is produced in the pilot plant of Fortum Oil and Gas (presently Neste Oil, Technology Centre of the Porvoo Refinery). The plant includes patented multi-inlet cyclones for effective reduction of solids content in the product liquid and is an integrated process which includes biomass reception, size reduction crusher, flue gas drum dryer, pyrolysis reactor, vapour recovery units, aerosol removal units and mixing tanks. The heat produced by combusting the car and non-condensable gas by-products of the process is used for feedstock drying. The plant is fully automated and includes all modern safety features.
