oil spill dispersion must take all the precautionary measurements required before the beginning of the process. IMPORTANT INFORMATION Toxicity According to the European Union (EU) laws, the MARICHEM OIL SPILL DISPERSANT is in the class of chemical dispersants that ful ll the limits of non–...
If the spill is in a tropical region, chemical dispersants are usually employed. These work by breaking the oil apart and allowing it to mix with water. They are most effective if used within a couple of hours of the initial spill. When the oil breaks apart, it forms droplets of oil an...

Oil dispersants (chemical agents such as surfactants, solvents, and other compounds) are used to reduce the effect of oil spills by changing the chemical and physical properties of the oil. By enhancing the amount of oil that physically mixes into the water, dispersants... (展开全部) 我来说...

Sometimes, these chemical dispersants adversely affect non-mobile marine species 6. Other Methods Some other methods employed for safer oil spill cleanups from the sea are hot water washing or washing with high-pressure water, manual labour, bioremediation, and natural recovery. ...
Unfortunately, some people still consider the use of chemical dispersants and the controlled burning of oil as “alternative” oil spill response options. Decades of research, controlled field trials and experience during actual oil spills have proven that the application of chemical dispersants and the...
Chemical remediation techniques use dispersants and solidifiers to clean the oil spill (Dave and Ghaly, 2011). Biological remediation techniques employ microorganisms that speed up the natural degradation of oil components (Atlas and Cerniglia, 1995; Dave and Ghaly, 2011). In Thermal remediation ...
