Chemical Dispersant

The problem with chemical dispersants is that they only eliminate the visual presence of the oil on the surface, while distributing the oil through the water column.

Watch step by step as WPI Chemical Engineer Marco Kaltofen performs an experiment using actual crude oil from the BP well and Corexit 9500A, the oil dispersant used by BP in the Deepwater Horizon disaster. Mr. Kaltofen demonstrates how Corexit suspends the most toxic hydrocarbons in the water column by a factor of about 35X more than absorbtion from crude oil alone, which floats to the surface in its natural form. BP used close to 2M gallons of this dispersant at the base of the blown out oil well and at the surface of the Gulf of Mexico, allowing this substance to mix into 5000 feet worth of water from the base of the well.
