1. GULF OIL SPILL An Engineering Challenge For Future Generations ….and that means YOU!

2. PLEASE..help me fly again!

3. 150 mi

4. Deepwater Horizon Blowout A lot of oil! 210,000 gallons per day at maximum Estimated 175 million gallons total Volume of 1 class room is about: 150,000 gal Over 1,000 classrooms of oil! About 75% still in the ocean

5. Deepwater Horizon Blowout Blowout was 5,000 ft (1 mi) underwater Most of the oil rises to the surface because oil is less dense than water. Some of the oil gets trapped in underwater currents and can travel throughout the ocean

6. Waves of Oil

7. Clean-up Methods 1.Dispersants: break up large oil slicks into small particles 2.Booms: long floating tubes that are put on the water surface to contain an oil spill 3.Skimming: specially designed boats “scrape” the oil off of the surface 4.Absorbents: materials that can help “suck-up” the oil

8. Dispersants Dispersants are chemical solvents or surfactants. They don't eliminate oil, they make it less obvious by breaking it into small pieces which spread throughout the ocean. The dispersant used by BP is toxic to microorganisms and fish eggs.

9. Booms Help contain the oil slicks on the ocean surface Used to protect shore line

10. Human Hair & Sheep’s Wool Wool adsorbs oil oil sticks to the hair does not soak into it Why? Oleo-philic surface Oleo = OIL Philic = LOVING ↘“Oil-loving” Attractive to oil!

11. Recycled Cellulose Material Made of recycled natural plant material Absorbs the moment it touches oil This material is hydrophobic so it repels water while absorbing only oil

12. Oil Absorbing Polymer Envirobond 403 is a polymer specifically formulated to bond to crude oil Bonds to hydrocarbons (oil) to form gel Hydrophobic – doesn’t absorb water

13. Oil Clean-up Experiment Follow the instructions on the handout Record your results Ask if you have any questions!
