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.
