Type: Dispersant (Corexit 9500/9527)
Primary Use: Nearshore/Offshore
|
Use:
COREXIT 9527 and COREXIT 9500 are used to disperse oil spilled
on the sea, thereby minimizing its environmental impact.
Description:
COREXIT 9527 is a blend of oxyalkylate polymers, organic sulfonic
acid salt, substituted fatty ester, and glycol ether. This is a
concentrated and highly effective oil spill dispersant for use
on a wide range of oils. The unique formulation of COREXIT 9527
provides a self-mixing dispersant that is biodegradable and of
low toxicity. Based on laboratory tests, COREXIT 9527 is effective
on most spreading oils. As with all dispersants, timely application
ensures the highest degree of success.
COREXIT
9500 is a high-performance, biodegradable, low toxicity oil spill
dispersant that is effective on a wide range of oils, including
the heavier, more weathered oils and emulsified oils. COREXIT 9500
contains the same well proven, biodegradable and low toxicity surfactants
present in COREXIT 9527, with a new improved oleophilic solvent
delivery system.
Aerial
spraying: provides the most rapid method of applying
dispersants to an oil spill and a variety of aircraft can be
used for spraying.
For aerial spraying
the dispersants are applied undiluted. A typical treatment
rate is two to ten US gallons per acre.
Typical application
altitudes of 30 to 50 feet have been used, although higher
altitudes may be effective under certain conditions.
Boat
spraying: the
dispersants may also
be used by boats
equipped with spray
booms, or fire water cannons.
Handling
and storage: this material can
be stored in
high density polyethylene, stainless steel, or double epoxy
phenolic
coated carbon steel
containers. The containers should
always be capped
when not in use
to prevent contamination and evaporation. Carbon steel and
aluminum are
not recommended
for long-term storage.
