2. Therma-Flite screw
processors: high-efficiency,
low profile
Drill Cuttings Dryers
With a state-of-the-art screwconfiguration, our processors
deliver greater heat transfer surface
per cubic foot of equipment than
other thermal processor technology.
This efficient design means an
extremely powerful unit that packs
high-impact processing in a compact
footprint.
PROCESS 1.5 TO 500 TONS PER DAY WITH 99.5% HYDROCARBON RECOVERY
Therma-Flite Holo-Scru® thermal
desorption systems volatilize and
recover 99.5% of hydrocarbons
from drilling mud. Oil, diesel and
other synthetics are often used as
lubricants in drilling for natural gas.
After this mud is recovered and
centrifuged, the slurry typically
contains high levels of water, diesel,
even crude oil.
The way it works is simple. Feed stock
is treated through controlled heat (or
cold) conduction, so it is never degraded
or contaminated by interacting with
material necessary to operate the unit
(water, steam, oil or gas). Feed stock
flows like clockwork through the ThermaFlite screw processor, and is exposed only
to a consistent, pre-set temperature for
accurate thermal processing.
Holo-Scru® processes can accept
feed stock with hydrocarbon
percentages greater than 70%,
effectively collecting and condensing water, diesel and other hydrocarbon vapors. In applications
such as natural gas drilling where diesel and water constitute the liquid phase, diesel is typically
filtered, then resold or reused as a lubricant for future drilling. Therma-Flite units in operation in
the U.S. process drill cuttings from shale drilling; This feed stock is generally 10% to 30% diesel,
and 20% water. Recovery rates for diesel typically range from 97% to 99.5%.
Decades of reliable performance and
innovation
In 1939, Therma-Flite (then Christian
Engineering) designed, built and sold the
first Holo-Scru® heat exchanger for the food
business. After World War II, Holo-Scru also
became widely-used in the chemical and
construction industries.
Therma-Flite sets the world standard in screw
conveyor technology and auger design, as
well as manufacturing equipment for the
chemical and processing industries. Our
processors last longer, and process a larger
quantity and variety of material than any
other manufacturer, bar none.
The Therma-Flite difference is that we don’t
simply sell equipment, we deliver solutions.
Every order begins by taking into account
the specific objectives and specifications
of our customer. We then take great
care in engineering flight designs, rotor
configurations, heat-transfer mediums,
and making proper material selection for a
processor that will stand the test of time,
and exceed your expectations.
Need portability? Mobile units
are now available for field testing.
Tank Bottom Sludge and Soil Remediation
CONDENSE AND RECOVER HYDROCARBONS IN ONE EASY STEP
If storage tanks storing crude
oil are not cleaned regularly, dirt,
water and oily sediment at the
bottom of the tank can be disturbed,
and contaminate the contents.
Therma-Flite Holo-Scru® desorption
units heat residual material to
1,000-plus-degrees Fahrenheit, so
that hydrocarbons and water vapor
are condensed and recovered.
These tank bottoms may also be
discarded after they have been
thermally treated to recover hydrocarbons. Multi-stage systems make the process even simpler
by removing water in one unit, while removing hydrocarbons in a second.
• There are Therma-Flite Holo-Scru® installations that have been in operation for more than 20
years processing tank bottom sludges and other feed stocks such as soil and catalyst fines.
Hazardous Waste Processing
DELISTING RESOURCE CONSERVATION AND RECOVERY ACT (“RCRA”) WASTE
Therma-Flite
Holo-Scru®
desorption units are excellent for
delisting RCRA waste. Drums, cans,
glass and plastic containers are
just some of the items that carry
hydrocarbon-laden materials such
as paint, perfume, degreaser, oil,
resins, and hair spray. Such feed
stock is typically shredded to 2-inch
minus in order to add easily to the
desorption unit. Holo-Scru handles
the shredded metal and glass quickly
and efficiently. Sticky materials are also handily-processed by virtue of the system’s self-cleaning,
rotor design. Process temperatures between 850 and 1,200-degrees Fahrenheit (depending on
feed stock requirements) volatilize all hydrocarbons.
3. Truly Ingenious Technology
YOUR CHOICE OF HEAT TRANSFER MEDIUMS: THERMAL OIL, STEAM, LIQUID SALTS, AND WATER
Therma-Flite Holo-Scru® thermal desorption systems are turn-key, and include all necessary components to:
• Hold and meter feed stock into the desorption chamber
• Provide an airlock to the inlet and discharge of the unit
• Cool the material exiting the desorption chamber
• Condense volatiles for collection
The feed system may be customized, but the standard system includes a feed screw with loading trough, or for applications
when feed storage is required, a feed hopper with integrated live bottom. For low viscosity sludges, such as drill cuttings
containing diesel and water, a positive displacement pump is used to feed the unit. Feed stock is discharged from the feed
screw into a double knife-gate airlock. The airlock cycles to allow feed to enter the airlock chamber while maintaining a seal
to the desorption chamber. For added safety, the airlock includes optional fittings for a nitrogen or CO2 purge which can be
used to insure any air remaining in the airlock is displaced prior to the airlock cycling, and discharging the feedstock into the
desorption chamber.
The heart of the system, the desorption unit, includes intermeshed Holo-Scru® rotors. In this chamber, feed stock is heated
under a slight negative pressure in a sealed, anaerobic environment; heating is indirect. Thermal fluid is circulated throughout
the Holo-Scru® rotors and outer jacket of the desorption chamber. The proprietary Holo-Scru® dual rotor design is self-clearing
and feed stock which might otherwise bake on to the rotors, is easily removed. Different mixing programs may be set in the
Programmable Logic Controller (PLC) which will increase the heat transfer into the feed stock.
A variety of heat transfer fluids may be used to heat product up to 850-degrees Fahrenheit. A second stage system can be
incorporate to heat the product to above 1200-degrees Fahrenheit. Most feed stocks may be de-volatilized to less than .05%
remaining hydrocarbons. As the heated solids exit the desorption chamber, they pass through a second airlock and into a
cooling screw conveyor. In the cooling screw, solids are indirectly cooled by circulating water through the jacketed wall of the
screw. The temperature is further reduced by direct-contact quench cooling via atomizing sprays along the top of the cooling
screw housing. The vapors exit the unit into a Venturi-effect, multi-stage condenser. Cooled and filtered condensate is used as
the condensing fluid. The Venturi-effect condenser is highly-efficient with less than .01% hydrocarbons remaining in the noncondensable stream. The non-condensable stream is released through a duct to the air intake on the diesel generator providing
the unit’s electrical power.
