PowerTreat* DA9066
Dust Control and Anti-Oxidant Agent
CoalPlus* Treatment Program
Reduces dusting during loading, unloading,
stack-out and reclamation.
Retards the oxidation and weathering of subbi-
tuminous coals, such as Powder River Basin
(PRB) coals.
Significantly reduces hot spots, smokers and
spontaneous combustion at active storage piles
surge bins and coal bunkers.
Description and Use
PowerTreat DA9066 is a patented dust control
binder/anti-oxidant designed to reduce fugitive dust
emissions and inhibit the surface oxidation of subbituminous coals. It is particularly effective on Powder
River Basin (PRB) coals.
PowerTreat DA9066 combines the functionality of a
long-term “residual” dust control binder, with an
anti-oxidant capability.
PRB coals tend to be dustier than other utility coals,
due to its inherent friability (ease of breakage) and
weathering potential (physical break down due to
oxidation). PowerTreat DA9066 prevents dusting by
two mechanisms – by agglomerating the fine particles as a binder and reducing the weathering of the
coal.
The anti-oxidant and dust control agents under the
CoalPlus program are not coating agents, but specially designed synthetic materials which inhibit the
surface oxidation reaction on the coal surface.
CoalPlus program materials irreversibly bind to the
reactive chemical sites on coal surfaces and inhibit
the oxidation reaction.
Typical Applications
For anti-oxidant and dust control applications on
active storage piles, PowerTreat DA9066 is typically
applied to the coal as it is unloaded from railcars or
barges. For optimum results, PowerTreat DA9066 is
applied using a foamed “body-feed.”
“Body-feed” is GE’s advanced foam system, incorporating state of the art dosing and monitoring
technology designed to provide maximum coverage of the coal surfaces with the product.
PowerTreat DA9066 can also be used as a water
solution; with spray nozzles for spot applications at
transfer points and during unloading, stack-out and
reclaim operations.
Treatment and Feeding Requirements
For anti-oxidant and dust control “body-feed” applications, PowerTreat DA9066 is fed through a foam
application system in conjunction with GE high performance foaming agents.
Foam or spray systems are customized for each
application depending on tonnage and feed location. Please consult with your GE representative to
select the appropriate foam feed equipment.
Neat PowerTreat DA9066 can be handled with appropriately sized gear or other positive displacement pumps suitable for viscosities up to
approximately 3000 cps. Contact your GE representative if you need more information.
General Properties
Physical properties of PowerTreat DA9066 are
shown in the Material Safety Data Sheet (MSDS), a
copy of which is available on request.
Packaging Information
PowerTreat DA9066 is a liquid product, available in
a variety of containers. Consult your GE representa-
tive for packaging and delivery options.
Storage and Handling
PowerTreat DA9066 should be stored in closed containers, at moderate temperatures of 40 to 90°F (4
to 32°C) and protected from excessive heat, sunlight and freezing.
To ensure maximum activity, this product should be
used within six months.
Spilled product is slippery, and precautions should
be taken to avoid such spills. If a spill occurs, cover
the product with an inert, absorbent material,
sweep up the spill, and place it in a waste disposal
container prior to flushing the area with water. The
wet area may be slippery, so sand, grit, or another
suitable material may be used to provide additional
traction.
Safety Precautions
A MSDS containing detailed information about this
product is available upon request.
