Environmental
Risk Potential and Preventions
The sulphur handling procedures with the Omni-Drop process
ensures molten sulphur is handled in a safe manner with 100%
containment by using limited vent sources and activated carbon
filters on those vents. If molten sulphur is spilled, it immediately
cools and changes to solid inert form. Site construction will
also ensure 100% containment of this type of incident by making
the site surface out of concrete and asphalt. Spills are simply
shoveled in to tote bags for landfill disposal.
During the process of mixing the molten sulphur with the bentonite
clay, the mixing tank will emit dust from the clay and trace
amounts of steam. The gas present in the sulphur is neutralized
and absorbed by the clay. A bin vent cartridge type filter
captures the dust emissions with 100% efficiency.
During the process of transferring the new slurry, the holding
tank air space is displaced and vented through an activated
carbon filter. This is merely a precaution as the slurry has
been neutralized from the mixing aspect.
The slurry is now transferred to the Omni-Drop unit's cooling
conveyor and solidified. As the new pastilles are being cooled,
the fumes are collected from the exhaust hood by a suction
fan. There are no gases present at his phase, however, there
are particulates (sulphur dust) in trace amounts. The exhaust
air is pushed through a mesh filter in order to capture the
dust completely. The finished pastilles are now collected
by a conveyor and transferred up in to bulk storage bins.
The pastilles are sprayed with a special dust control agent
before they enter the bins. This is done in order to provide
the customer a dust control advantage when he is handling
the material. This also eliminates any dust emission potential
from the storage bins, bulk truck loading point and packaging
center.
