  6. Material Balances

  7. Extraction Data • Hexane Usage: • Extractor: 73,566 Gallons • Work Tank: 16,050 Gallons • DT: 13,376 Gallons • Dist. : 6,688 Gallons • Total: 109,679 Gallons • Hexane cost • $134.72 per Gallon • Cost: $14,776,284

  8. Extraction Data • Mineral Oil Usage • 10,000 Gallons • $19.51 per Gallon • Cost: $195,100 • Cooling Water Usage • 14,713 GPM • 10 degree max temp. rise • Steam Usage • DT: 53,503 lb/hr • Total: 108,342 lb/hr

  9. Comparison of Microalgal Oil and Diesel

  10. Rough Excavation Cost • Need approx 25,000 of 980.0 square meters of 0.30 meter deep trenches for raceway ponds. Is approx 10,337 cf of “dirt” removed for each pond. • Excavation includes machine excavation with front end loader or backhoe, two trucks with 30 minute trips per load. Dumping fee not included. • Have not taken into account any tree or rubble removal from site or any concrete laying etc. Only dirt dig and removal.

  11. Rough Excavation Cost • May be able to sell dirt from dig. • Labor cost is $1,156 • Cost of removal of cf of “dirt” is $7,649 • Total is $8,805 (per pond) X 25,000 ponds = $220,125,000 • Estimated from online calculator “HomeTech Cost Estimator”

  12. Plant Cost • Algae Production • $220,000,000 • Does not include cost of PBR tanks and FDSF • Extraction • $24,000,000 • Scaled from soy crush plant estimates • Biodiesel Production • $183,564,777 • Scaled from DOE data

  13. Plant Cost • Total Estimate • $427,564,777
