Alberta’s oil sands contain the largest known
reserve of oil in the world. An estimated 1.7 to
2.5 trillion barrels of oil are trapped in a
complex mixture of sand, water and clay. The
percentage of bitumen in oil sand can range
from 1% - 20%. The oil saturated sand deposits
left over from ancient rivers in three main areas,
Peace River, Cold Lake and Athabasca. The
Athabasca area is the largest and closest to the
surface, accounting for the large-scale oil sands
development around Fort McMurray.
Mining
Since the 1920's, open pit mining has been central to oil sands development. Mining
equipment from the early years was scaled up significantly when large commercial
operations started to come on line, including bucketwheels, truck & shovel and large
scale draglines. A variety of methods have been employed to transport the material
to the plant and off to tailing reclaim areas. The most popular now is “Hydrotransport”,
conversion of the raw sand to a slurry and hydraulically pumping to and
from the processing plant
Extraction
Oil sand is mixed with hot water creating a slurry. Hydro-transport pipelines are used to condition and transport the oil sand from the mine to the extraction plant. The slurry is fed into a separation vessel where it separates into three layers - sand, water and bitumen. The bitumen is then skimmed off the top to be cleaned and processed further.
Townley is relatively new to this area, but with 40 years providing abrasion and corrosion solutions to the mining industry, many products seem a natural fit.

UBD
– HTP Hydrotransport pump - With more than 150 in-service,
these unique UBD slurry pumps are in use from the pit to booster to tailings
circuits. Designed to solve wear problems associated with conventional
impeller/volute designs, these pumps have a patented recessed volute with
matching impeller. Coupled with a contoured suction port, these patented
features reduce recirculation and provide hydraulically clean solution-flow
through the impeller to the discharge. Available in alloy or urethane
lined to match your application.
Pump
Parts - Townley has an extensive inventory of parts and patterns
for most common slurry pumps in service. We can provide improved wear
with proper material selection. Cast alloys, replaceable urethane liners
or permanent urethane lined shells, impellers and suction plates.
Series
1000 Suction & Discharge Hose - Reduce vibration and provide
easy transition for older plants with fit problems. Available in straight,
reducer with outlets or taps. Eliminate OEM multiple pipe assemblies with
one P/N. Most any lengths, wear tubes material and I.D.
Super
Flex Hose - This versatile hose has found new use in coal plants,
especially in tailing and transfer lines as a strain relief for rigid
pipe and to ease runs over uneven terrain. Also can be found in suction
and discharge use where severe flexure is required. In the process plant,
this universal hose is used as a replacement for high wear rigid pipe
and areas where 3D movement is expected.
MSP
Submersible Slurry Pump - Cost effective
replacement for vertical cantilever style sump pumps. Available in 2”- 10” with 5-150 HP. Standard high-chrome
wetted parts. Easily moved with lifting bail and Townley
flex discharge hose. Perfect for coal tunnel, sumps and waste water run-off. Optional multiple sensor protection box to ensure pump life.
80
TP Knife Gate Valve - Townley’s most versatile bidirectional
valve features a unique bonded-in Towniprene urethane lined body and seat.
Coupled with a precision stainless steel gate & stem, this valve is
perfect for slurry diversion and isolation with assurance of easy actuation
when you need it. The unique flush bottom of the seal ensures no clogging
or trapping of debris to prevent positive sealing. Townley offers a complete
rebuild service back to factory specifications.. Available in 2”
to 96” I.D.
80SCEHA
- This self contained electric powered hydaulic valve is perfect for remote
or isolated areas of your plant where factory air and hydraulic lines
are not practical. AC or DC these units can be remotely actuated with
a "DeviceNet™" interface. Especially useful in settling
ponds or containment areas.
Series
150 - Heavy Duty Slurry - This heavy duty, high pressure fabricated
valve can be customized for your application with seats constructed of
wear and chemical resistant alloys or Towniprene urethane. Features an
easy open gate when under high pressure while handling slurries or coal
ash. Perfect for Bottom ash use where custom drilling or custom dimensioning
is required along with higher pressure service.
Hydrocyclones
(classifying or de-watering) - Townley High-performance cyclones
are designed and manufactured with a Towniprene urethane cone body and
bolted apex. Constructed with a urethane lined tangential feed chamber,
fluid pressure is converted into rotational momentum, providing centrifugal
classification or dewatering of solids from slurry. Featuring durable
one piece
urethane cone body to retain shape and reduce wear ridges.
Custom fit to your application, 4” thru 48”cone body with all
critical parameters designed to suit application requirements.
Custom
overflows, apex splash guards, distribution headers and launderers are
available to meet your specifications
Urethane
Gaskets and Wedges - Maintenance friendly describes these simple
products found in many power plants. Especially useful for older plants
to offset misaligned fittings or couplings. Wedges can be used for slight
turns in pipe without the expense of fabricated pipe. Designed with a
handle to ensure precise alignment between flanges, this feature doubles
as a "finger saver." Townley can easily design custom sizes
and formulations for your application.
