Marine damage

How to deal with the oil pollution?

• Exert toxic effects on marine organisms• Pollutes benthic and coastal organisms

Spraying dispersants on spilled oil

The spilled oil in the marine environment will be biodegraded. Dispersants break spilled oil to small droplets, the droplets could facilitate degradation by micro-organism.

Functions of Dispersants The dispersants are generally long chain compounds (hydrophobic

end) with polar groups (hydrophilic end)such as carboxylate, sulfonates, or phosphate.

Dispersants decrease interfacial surface tension between the water and oil and facilitate the transfer speed of oil from the water surface into the water column to mitigate oil spill impacts.

• Oil PropertiesOil composition (viscosity, etc.)Slick thicknessCrude oil, fuel oil , gasoline, etc.

• Dispersants SelectionDifferent dispersants will have different effectiveness.HLB value of the dispersant is a vital factor in producing a stable

emulsion.

• Environmental FactorsSurface wave energySeawater salinityTemperature

How do the aid work?CSHOPAX SPECIALITY CHEMICALS

Spraying dispersants Spraying dispersants with HOPAX aid

• Enhance degradation of spilled oil (physical and biological)• Significant sedimentation of spilled oil• Extend micro-organism degradation time

Laboratory TestsA DCB

A. Oil spill dispersant emulsify crude oil in sea water.B. Other polymer agent can not work.C. CSHOPAX Aid in crude oil has significant sedimentation of oil drop, but without emulsification.D. Oil spill dispersant with HOPAX Aid emulsify crude oil in seawater.

The tests demonstrate superior performance of oil spill dispersant with CSHOPAX Aid .
