  1. Welcome to the 2nd program meeting of the Centre of Black Liquor Gasification

  2. Centre for Black Liquor Gasification • Partners • ETC (coordinator) • Luleå University of Technology • Umeå University • Chalmers University of Technology • Chemrec AB • Åbo Akademi University (independent project) • Funding • Swedish National Energy Administration • Chemrec AB

  3. Piteå Black Liquor Gasification Development Plant (DP1) • Capacity 20 ton black liquor/day • Pressurised gasification @ 30 bar, 1000°C • Part of technical development program led by Chemrec AB • Black liquor from the Kappa Kraftliner mill • Complete gasifier, chemical recovery unit and control system

  4. Piteå Black Liquor Gasification Develoment Plant (DP1) • Custom built extension of lab • 3 MWth (app.) gasifier • 20 ton black liquor/day

  5. Reactor principle

  6. Objectives with development plant • Demonstration of process reliability • Optimisation of gasifier components • Optimisation of construction materials • Determination of process characteristics • Optimisation of green liquor and syngas composition • Provide data for design optimisation of a commercial plant

  7. Underpinning research program at the Centre for Black Liquor Gasification • Focus on technical issues • Strong interaction with Chemrec’s technical development program • Readiness for unexpected problems • Develop key competence and experimental infrastructure • Generalisation of results from DP1

  8. Research areas Inorganic reactions (UmU, Åbo) Construction materials (Åbo) Computer modelling (LTU, ETC) • Gas phase reactions • Smelt formation • Green liquor quality Centre of Black Liquor Gasification • Corrosion • Smelt layer thickness • Gasification reactor • Quench • Counter current condensor Design verification program (Chemrec) Gasification reactions (CTH, Åbo) • Technical design • Kinetic models • Evaporation, pyrolysis, char conversion

  9. Research projects 1. Modelling, simulation and optimisation of a black liquor gasification reactor (Prof.R. Gebart, ETC) 2.
