Prevention of oil spilling using new and innovative technologies: Protei boat and Oman's ethnic plant Mulukhia El Bar.

1. OIL SPILLS: THE
CLEANUP
By New, Eco-Friendly Technologies

5. The BP Oil Spill
The BP Oil Spill was
one of the worst oil
disaster happened in
human history. 205.8
million gallons of oil
was leaked and it took
almost 8 months to
clean it.

6. Existing Methods of Cleaning
 Bioremediation
 Skimming
 Solidifying
 Use of Dispersants
 Controlled Burning

7. Dispersants
 A dispersant is either a non-surface
active polymer or a surface-active substance
 It causes the oil break up in water soluble
substance which later, can be diluted
 Corexit dispersant used by BP in cleaning up
the BP Oil Spill increased the toxicity of oil by
up to 52 times

8. Skimming
 It features a rotating drum, disc or
brush that rotates to collect oil off
the surface, and then places this
oil in a separate collection
device. The drum is often made
of oleophilic materials that
attracts oil to the drum. As the
drum rotates through the water,
this oil adheres to the exterior of
the drum and is removed from
the water

9. Commonly used Skimmers
 Disc Skimmers
 Drum Skimmers
 Weir Skimmers

10. Cons of traditional Skimmers
 It requires humans to spot the oil
 Can’t go very far from the shore
 It is Expensive
 It is Oil Driven
 It exposes the health of cleaners

12. Protei’s Robotic Boat
 It is autonomous, &
doesn’t need any
human for it’s
operation
 It can go anywhere in
deep water
 It is cheaper
 It is battery driven

16. Corchorus Depressus
 It is only found in Oman
 It’s Arabic name is
Mulukhia EI Bar which
literally translates to
“The Desert Queen”
 It is used for grazing
animals

17.  It contains 40-70% of AlCl3
 NaSo4
 H3Bo3
 It acts as a sinking material when used in
powdered form
 It absorbs the oil and settles to the bottom

18. Experimental Proof
 An experiment was performed and the
Chorcorus Depressus was compared with the
common dispersant Bentonite Clay
 Oil remained =
(Total gain in weight * 1000) /Sample in ‘ml’
 Oil removed =
Initial oil concentration – Oil remained.

21. Conclusion of Experiment
 The optimum removal efficiency of oil from the sample when
Corchorus depressus was used yielded 99.4% at 160mg/l oil
concentration and 20g of material, contact time being 20 min.
 The optimum removal efficiency of oil from the sample when
Bentonite clay was used yielded 80.6% at 160mg/l oil
concentration and 20g of material, contact time being 20 min.
 It has been deduced that the herb Corchorus depressus used
for separation of oil from seawater was the most effective and
efficient and at the same time proved to be economical

22. Conclusion
 Using technologies such as the Protei’s
autonomous shape-shifting boat or the use of the
ethnic herb named Corchorus Depressus, we can
clean up the oil more efficiently and more cost-
effectively.
 Both of these new methods of cleaning are eco-
friendly and can be very helpful in reducing the
damage caused to nature by the use of traditional
oil spill cleanup methods.
