Oil dispersant mechanism of action. An oil dispersant is a mixture of emulsifiers and solvents that helps break oil into small droplets following an oil spill.Small droplets are easier to disperse throughout a water volume, and small droplets may be more readily biodegraded by microbes in the water.
The 2018 Balikpapan oil spill was an oil spill off the coast from the city of Balikpapan, Indonesia. It was caused by a cracked pipeline linked to a Pertamina refinery in the city. A blaze that occurred when the oil spill caught on fire had killed five residents who were in the bay, in addition to causing respiratory problems in the city.
By comparison, Corexit, the oil dispersant used in the Deepwater Horizon oil spill, is rated at 54.7% effective against South Louisiana crude oil and three times as lethal to silverfish and more than twice as lethal to shrimp. [5] On May 20, US Polychemical Corporation was reported to have received an order from BP for Dispersit SPC 1000. [6]
This is a reverse-chronological list of oil spills that have occurred throughout the world and spill(s) that are currently ongoing. Quantities are measured in tonnes of crude oil with one tonne roughly equal to 308 US gallons , 256 Imperial gallons , 7.33 barrels , or 1165 litres .
Oil slicks on Lake Maracaibo Volunteers cleaning up the aftermath of the Prestige oil spill. Dispersants can be used to dissipate oil slicks. [54] A dispersant is either a non-surface active polymer or a surface-active substance added to a suspension, usually a colloid, to improve the separation of particles and to prevent settling or clumping.

A U.S. Air Force Reserve plane sprays Corexit over the Deepwater Horizon oil spill in the Gulf of Mexico. Corexit [1] (often styled COREXIT) [2] is a product line of oil dispersants used during oil spill response operations. It is produced by Nalco Holding Company, an indirect subsidiary of Ecolab. [3]
Chemical dispersants are used in oil spills to mitigate the effects of the spill and promote the degradation of oil particles. The dispersants effectively isolate pools on oil sitting on the surface of the water into smaller droplets that disperse into the water, which lowers the overall concentration of oil in the water to prevent any further ...
