1. Oil From [the] Soil Team 9 May 9th, 2009

2. Outline Project Selection Tasks Accomplished Challenges Overcome Lessons Learned Acknowledgements Questions

3. Project Selection Provided global industrial perspective Utilized and built upon prior coursework - Separation Processes - Reactor Design - Fluid Flow & Momentum Transfer Phenomena Received suggestions from Professor Sykes Waste vegetable oil from food operations Biological conversion of CO 2 to ethanol by sunlight

4. Our Design Process 1.Research a.What is Jatropha Curcas? b.How is biodiesel produced? c.Why Jatropha?

5. Grown in South America, Africa, India Ideal for poor soil and water conditions Seed’s mass is 30%- 40% oil What is Jatropha Curcas? 1 meter

6. How is Biodiesel Produced? Common process for various sources – Soybeans – Recycled cooking oil Base-catalyzed transesterification

7. Why Jatropha? PropertyConventional Diesel Jatropha Biodiesel Density (kg/m 3 )850880 Viscosity (mm 2/ s) 2.604.80 Flash point (˚C) 68135 Water Content (%)0.0200.025 1000 kg Jatropha seeds = 92 gallons biodiesel

8. Our Design Process 1.Research 2.Develop a.Process design with bench-scale trials

9. Bench-Scale Design Start Whole Jatropha Seeds Crushed Jatropha Seeds Hexane-Seed Slurry Hexane evaporated with heat Acid-Catalyzed Transesterification Base-Catalyzed Transesterification Separated Glycerol & Biodiesel Purified Biodiesel

10. Our Design Process 1.Research 2.Develop a.Design overall process with bench-scale trials b.Pilot plant simulation of chosen process

11. Simulated a biodiesel production pilot plant Produces 2 million gallons annually UniSim Design

12. The Process Seed Oil ExtractionTreatment & Conversion (Transesterification) Hexane & Methanol Recovery

13. Step 1: Extraction To Step 2

14. Step 2: Treatment & Conversion From Step 1 Treatment Conversion

15. Step 3: Hexane and Methanol Recovery Hexane RecoveryMethanol Recovery

16. Our Design Process 1.Research 2.Develop 3.Overcome a.Address emerging challenges b.Evaluate existing components

17. Challenges Overcome Troubleshooting UniSim design Unexpected & undesired experimental outcomes Accounting for entire footprint – Equipment sizing & material science – Economic analysis – Responsible design

18. Responsible Design Chemical safety – Flammability – Working conditions – Safe handling Waste management – Hexane & methanol recycling – Seed cake incineration – Sale of glycerol

19. Value of teamwork – Communication – Individual strengths/weaknesses Project management – “You break it, you bought it” Future work: Commercialize Lessons Learned & Future Work
