2. Progress in Biorefinery Case Studies
Biorefinery concepts
TEA for Biorefineries 2

3. TEA of Pyrolysis Biorefinery
What process concept (or concepts?)
Single concept in depth, or
Comparison of several concepts
Technical or Technoeconomic
Detailed mass and energy balance only, or
M&E balance to allow capital & operating cost estimate
What methods?
What level of detail? 3

4. Summary Numerous opportunities involving:
incorporation into sugar biorefinery
incorporation into a petroleum refinery
stand-alone with chemical, fuel, and power production
incorporation into a gasification and synthesis plant
Pyrolysis demonstration will lead to biorefinery
Product separation and recovery is a major hurdle
Finding the right niche is key 4

5. Biorefinery Concepts to be Evaluated
JR - Pyrolysis + CHP stand-alone (base case)
PNNL - Distributed pyrolysis to central refinery for upgrading and integration
Aston – Speciality chemicals and fuels
IWC – Pre-separation concept and pyrolyse products (lignin), maximise by-products and chemicals from the process, particularly phenols
FZK – Bio-oil/char slurry gasification + synthesis
BTG – Direct gasification of bio-oil in existing gasifier + synthesis 5
