  2. The Team Steve Pohler Eric Michel Nate Gifford Mark Dekker Caleb Mutschler

  3. Summary • Overview • Experimental accomplishments • Experimental Obstacles • Base case and UNISIM design • Final Design • Questions

  4. Overview • Use algae to convert CO2 to lipids • Convert lipids into biodiesel • Scaled to industrial application

  5. Preliminary Experiments • Growth studies on local algae • Conducted research on various strains • Chlorella vulgaris

  6. Pilot Plant Construction

  7. Pilot Plant • Algae was initially grown in growth chambers • Transferred to reactor • Bacteria was also introduced • Bacteria outcompeted algae for nutrients • Experimentation was discontinued

  8. Base Case • Developed a process flow diagram • Utilized UNISIM process simulator to model • Catalyst design decision • Early equipment selection

  9. Process Flow Diagram

  10. UNISIM • Developed biomass and triglyceride hypotheticals • Useful for early estimates of equipment sizing • Models liquid operations better than solid

  11. Final Design • Hand calculations to size equipment • Develop a piping and instrumentation diagram • Process costing • Feasibility analysis

  12. Obstacles • Reasonable sizing estimates of photobioreactor • Solids handling • Dewatering • Crushing
