CHIMSPERSE 4000

Dispersant for decontamination of sea pollution by oil

CHIMSPERSE 4000 is a next-generation dispersant specifically formulated for cleaning sea areas contaminated by hydrocarbons. Its use fragments crude oil into very fine droplets, enormously assisting in its degradation by the micro-organisms naturally present in the sea. It is effective in waters with different levels of salinity, such as sea and lake surfaces, as well as industrial water systems and water courses; it is applied to both calm and heavy seas using the dedicated lance or similar sprayers. The product requires dilution with water. CHIMSPERSE 4000 is totally biodegradable and is non-toxic for marine flora and fauna, as certified by an accredited independent laboratory; it has also passed tests for dispersant-emulsifier effectiveness, biodegradability, and toxicity for seaweed, crustaceans and fish, as required by the Italian ministry for the environment, and has received the corresponding

official approval. CHIMSPERSE 4000 disperses and emulsifies light and heavy hydrocarbons, as well as organic and biological fouling, pitch and sludge.

Mechanism of dispersion in treatment of OIL SLICKS

» The dispersant is sprayed on to the oil as droplets. The dispersant contains surfactants, made up of two parts: an

oleophilic part (oil-loving) and a hydrophilic part (water-loving) capable of emulsifying the hydrocarbons in water while

liberating the water included in the oil slick.

» The emulsion of oil in water which is formed disperses the hydrocarbons in small droplets, favouring their degradation

by naturally occurring bacteria.

» The emulsified oil in the form of small droplets does not inhibit oxygen-water exchange, and the oil droplets treated

with the surfactants which attach to their surface no longer affect the surfaces they come into contact with. The

dispersant can also be used as a cleaner of the surfaces made dirty by the oil spill.
