1 Fast pyrolysis demonstration - Increasing efficiency with integration to CHP October 27, Joakim Autio, Valmet Technologies

2 How to enable global economic growth without risking the world s sustainable future? More people higher demand for energy, fiber, fuels, and commodities Population growth Global warming Clean air Fresh water Dependence on fossil fuels Arable land Biomass and residues Waste 2

3 Valmet s target in technology development is to create sustainable results for its customers Sustainability goals drive our technology development Creating value to our customers Lower energy consumption Lower fresh water consumption Utilization of renewable energy High raw material utilization and increased recycling Compliance with authority regulations is only a minimum strive improve the HSE through out our value chain and answer to social expectations Positive sustainable image to attract both customers and talent Less chemicals Emission reduction Improved business performance: growth and profitability with smaller environmental footprint 3

4 Valmet s technology and services offering Converting renewable resources into sustainable results to create the future Endproducts Biogas Biofuels Biochemicals Biomaterials New paper grades Heat Electricity Diss pulp Chem pulp Mech pulp Paper Board Tissue Valmet technologies and solutions Energy Pulp Paper Raw materials Waste Agro Wood Recycled paper 4

5 Valmet s R&D: Moving our customers performance forward Ideas Feasibility Laboratory Pilot Demonstration Commercialization Our customers present and future needs drive our R&D forward Close co-operation with our customers Wide and synergistic competence base Extensive global research network Own R&D centers with pilot operations Long track record in development and scale-up Increased production efficiency and availability Improved cost competitiveness Widened raw material base and fuel mix Maximum value from renewable raw materials Minimum environmental impact 5

6 Long-term R&D co-operation with partners produces results Pyrolysis as an example 1980 s First Finnish R&D laboratory studies on pyrolysis (VTT) 2007 Technology development consortium formed (Valmet, UPM, VTT) Tekes support starts Cold model tests for oil production start at Valmet R&D Center in Tampere 2010 Pyrolysis oil combustion tests Start of concept planning for a commercial demo plant R&D projects on pyrolysis oil upgrading on-going Press release March 11, 2014 Fortum, UPM and Valmet are jointly developing technology to produce advanced biomass based fuels 1990 s First R&D projects including Finnish companies 2009 Fortum joins development consortium Bio-oil pilot tests at Valmet R&D Center starts 2012 Fortum and Valmet sign contract on Joensuu plant 2013 Commissioning and commercial operation of Joensuu plant June 30, 2015 Joensuu plant handed over to Fortum 6

7 Six full-scale new biotechnology projects Biomass gasification Waste gasification Medium BFB < MW Biomass indirect e gasification Integrated pyrolysis Vaskiluodon Voima, Vaasa, Finland Lahti Energia, Lahti, Finland GoBiGas Göteborg Energi, Sweden Fortum Joensuu, Finland 140 MW gas to replace coal in PC boiler 2*80 MW Waste 20 MW SNG 30 MW bio-oil Lignin extraction Domtar Plymouth, NC, USA ton/a lignin Lignin extraction Stora Enso Sunila mill, Finland ton/a lignin 7

8 Integrated pyrolysis oil production technology Valmet DCS High pressure steam Turbine Electricity Non-condensible gas District heat Woody biomass Condenser Crusher Drying Fluidized bed boiler Pyrolysis unit Bio-oil 8

9 Bio-oil production integration to a CHP-boiler Symbiosis of two processes: Efficient use of back-pressure steam and low temperature heat for drying Char and non-condensable gases burned in the boiler Plant energy efficiency ~90% CO 2 -reduction ~90% With constant heat load: 5 % more electricity 5 % less raw fuel usage 9

10 Bio-oil production integrated to a CHP-boiler Integration to main power plant Integrated pyrolysis forms a minor addition to existing boiler plant equipment compared to stand-alone bio-oil production plant Stand alone bio-oil production plant: - Green: Pyrolysis equipment - Blue: Char combustion and heat recovery Bio-oil production integrated to CHP-boiler: - Green: Pyrolysis equipment - Grey: Existing boiler plant 10

11 Bio-oil production integrated to a CHP-boiler Joensuu t/a bio-oil production plant turn-key delivery by Valmet Pyrolyzer in boiler building Bio-oil recovery Feedstock drying and crushing Bio-oil storage tanks Feedstock receiving 11

12 Bio-oil production integrated to a CHP-boiler Joensuu t/a bio-oil production plant Plant completed late 2013 as scheduled Full bio-oil production capacity is reached during 2014 Pyrolysis operation has been in accordance with earlier pilot experiences Oil quality according to specifications CHP operation has been undisturbed Char combustion Bed material circulation Some scale related issues noted and corrective measures taken Plant handed over to Fortum in June 2015 Co-operation continues with research and development 12

13 Combustion of bio-oil Know-how and experience of combustion of fast pyrolysis bio-oils generated in several scales R&D for pyrolysis oil combustion in joint research projects Valmet has specially developed and optimized burner types for pyrolysis oil The whole end use chain from tank to stack can be quoted 13
