In 2013 OSHA released this Hazard Alert the Hydraulic
Fracturing industry. Our System was recommended as a acceptable
solution by NIOSH. In 2011 Imperial Systems recognized a serious
hazard to health and environment through exposure to displaced
silica laden air. This is created from the high velocity transfer
of sand used in the fracturing process. The polluted air is emitted
to atmosphere. In addition to serious health concerns for those in
the area, effects to the environment are an unfortunate
consequence.

Three Acceptable solutions according to NIOSH 1.Centralized
system with hoses and manifolds (Major Set Up Time and Cost). These
systems can be over $100,000 is just equipment cost. 2.Imperial
Systems Dust Pig mounted on APPCO trailer. No set up required.
Handles dust at all points of concern. Imperial Systems Method is
the only system on the market that requires no additional labor to
operate and captures 100% of emissions at source. Cost for a unit
is approximately $25,000 for the equipment. 3.Simple bags (Major
issues with weather, no cleaning mechanism, very dirty, worker
exposure.) Cheap alternative that is ineffective.
Slide 5
Solution: Imperial worked to create a solution with the
transfer/ storage equipment and the onsite end users. Our answer,
the Dust Pig, is universal to all equipment and technologies where
the material transfer process exists on fracturing job sites. The
Dust Pig and all dust collection processes are patented by Imperial
Systems for all fracturing work sites. Dust Pig

As sand is loaded the doors on top are opened to relieve excess
pressure. This allow sand to escape. This is a video of that
process without using our dust collector.
Slide 7
This is video of the area around the sand storage unit when the
doors are on top and sand is allowed to release. Notice the dust
collector connected to the drum.
Slide 8
This video shows the doors on top shut as the sand is loaded
from the trucks on the right. The dust collector is running
balancing the excess pressure and collecting the sand.
Slide 9
Another video of the area while sand is being loaded. Notice no
visible sand is in the air.
Slide 10
Flow This diagram shows how the dirty air inside the storage
unit flows to the collector (on the left). Sand is captured by
filters and clean air is released. The internal working of the dust
collector automatically clean the filters and deposit the sand in a
drum (not shown). Dust Pig
Slide 11
Process: We balance the displaced air created by excess
pressure when transferring through the system and collect the
particulates. Our proprietary technology for cleaning and our
patented dust collection process is the only practical recognized
option for these methods. As the sand is blown in the trailer the
evacuated air is captured in the Dust Pig (instead of escaping
through the open doors on top), particulates are filtered and clean
air is exhausted to atmosphere. The other points of capture is the
material transfer from the stingers to the multi sander and from
the multi sander to the blender. This is done without the need of
additional set up or field work as the unit is mounted directly to
the equipment. Dust Pig Doors
Slide 12
Results of Solution: The on-site process/ procedure used to
transfer the sand is not changed. The truck mounted Dust Pig simply
works by allowing the openings on top of the storage unit to be
closed and flowing the dirty air through the Dust Pig collector.
Central system that address all potential dust sources. Operators
simply operate the equipment and load sand as they always have with
zero labor required to run the dust collection equipment. The
initial, uninstalled cost of the equipment is approximately
$25,000. Imperial has over 100 of these units running in the United
States and Canada. The result is a user friendly, inexpensive,
simple process that provides clean air for persons affected and a
positive effect on the environment.
