This document discusses solutions for transporting proppants from mines to well sites. It proposes using flat rail cars with container liners to keep proppants in the same container throughout delivery without needing bulk trucks or special equipment. This allows for door-to-door delivery and fast transfers using standard trucks. The document also describes different types of container liner bags for transporting proppants by rail, including barless and woven liners made of durable materials.

Proposed Solution
Transloading from Mine Silo into Bulktruck Through Rail
Flat Car with Container Liner
1. Product stays in the same container from door to door delivery
2. No need for costly bulk trucks
3. No need for special transloading equipment at the rail yards
4. Fast transfers at the rail terminals
5. Any truck can deliver the cargo
6. Simple equipment to load at the mine and to unload at the well into the silo
7. No idle times. Tractor delivering the loaded container, can drop off container and pick up for return an already
emptied container
8. Containers can offer temporary storage.

5. BARLESS High Performance Bulk Container Liners

• Eliminates costly steel bars.
• Saves on the Logistical operational
costs of having to import the steel bars.
• No risk of steel bar injury by coming
out of the container under the load
pressure.
• Safest liner-bag in the industry: Liner
strong enough to discharge without
steel bars, but if desired, for safety
redundancy purposes, Steel Bars can be
added in the container channel slots at
destination prior to tilting.
• No loss of payload due to its
proprietary design that does not reduce
liner-bag volume.
• Installs in 8-10 mins with no
additional belts or straps to tie.

6. Woven High Performance Container Bulk Liners
• Proprietary manufacturing system with these
benefits:
1. Eliminates the risk of spills due tobroken seams
with faulty stitching.
2. Eliminates the risk of contamination from loose
threads due to stitching.
3. Humidity cannot penetrate through the seams
• Highest lamination thickness in the industry for
additional humidity protection (30 gsm/1oz per yd2)
• Due to the strength of proprietary clips attached to
the liner’s floor end, each liner comes with the
possibility of using a rope or a steel bar on the front
floor end. Potential saving of 1 steel bar.
• Fast installation with elastic cords and metal carabine
hooks.
• Pull-up top steel bar in the bulkhead guarantees
discharge ports fully accessible at all times.
• High quality non-stretchable belts ensures bulkhead
and steel bars position at all times.
• Made of FDA food grade virgin HDPE resins at clean
facility.

7. PE FILM High Performance Container Liners
• HIGHER THICKNESS: BULK-FLOW standard Film thicknessis 140
microns.Due to the high tolerancesin films, 120 microns PE films
pose the risk of weak spots beyond acceptablefilm strength
tolerances.
• NO EXTERNAL WELDED SEAMS: BULK-FLOW PE film Body Liner
tube is made longer so it can be folded at the end and avoid any
type of long external welded seams that are the weak point of the
Liner. The only welded seam is a single point where all the folded
tabsmeet and it is inside of the Liner.
• OPTION TO USE 4 OR 5 STEEL BARS: Due to the strength of
proprietary clips attached to the liner’s floor end, each liner comes
with the possibility of using a rope or a steel bar on the front floor
end. Potential saving of 1 steel bar.
• HEAVY DUTY BULKHEAD: Unique design that uses a longer tube to
be folded on the ends and avoid long welded seams. The outer
Woven Bulkhead is also made of folded Woven HDPE with a total
thickness of 280 gsm (9oz/yd2)Fast installation with elastic cords
and metal carabinehooks.
• PROPRIETARY FULL FLOOR FLUIDIZING SYSTEM (OPTIONAL): Built-
in fluidizing system for hard-to-flowproducts
• GUARANTEED FULL ACCESS TO DISCHARGE PORTS:
• Pull-up top steel bar in the bulkhead guarantees discharge
ports fully accessible at all times.
• High quality non-stretchable belts ensures bulkhead and
steel bars position at all times.
• HIGH QUALITY MATERIALS: Made of virgin HDPE resin with
extraordinaryelasticity and FDA compliant.
