From Indirect Thermal Desorption
Drum Dimensions: 76 inch Diameter x 48 feet length. Processing Capacity: Light Oil Waste: 7-9 TPH. Heavy Oil Waste: 2-4 TPH.
Indirect Thermal Desorption
Indirect Thermal Desorption is a remediation technology designed to separate the organic constituents from a waste stream so they can be preserved for collection and recycling.
Our process starts with material going into the ATDU. Material is transferred to the receiving hopper of the feed system using a front-end loader or crane. An inclined conveyor takes the material from the hopper and transfers the feed to the ATDU through a double tipping valve assembly. Material to be furnished to the ATDU is to be all two (2) inch minus five (5) centimeters.
The ATDU is an indirectly heated rotary drum that is operated in a parallel flow configuration. The burner flame and exhaust gases do not come into contact with the contaminated material. The drum rotates within an insulated chamber that can be heated by combination fuel burners capable of burning natural gas, fuel oil, syngas or propane. As the drum rotates, the contaminated material exposed to the metal surface is continuously renewed, facilitating the transfer of heat from the heated chamber through the drum to the material. The material is then heated to a sufficient temperature to volatilize the contaminants. This is achieved under anaerobic conditions, which prevent oxidation of the hydrocarbons or chemical compounds.
The processed solid material is discharged from the ATDU through a double tipping valve. It is deposited into a pugmill mixer-cooler (standard) where water is injected and mixed for direct contact material cooling. Optional jacketed screw conveyors are available for indirect cooling. With either option, the hot discharged material from the ATDU is cooled using direct or indirect contact with water.
After exiting the ATDU, all process gases undergo a recovery/condensation and cooling process in the Vapor Recovery Unit (VRU). The condensables are processed in the Oil Water Separator (OWS) which is an integral part of the primary Water Treatment Unit (WTU). The recovered water and sludge from the WTU are stored in tanks or roll offs as required by the operator.
Benefits
The innovative design and function of our Anaerobic Thermal Desorption Units provide benefits for oil and gas job sites around the globe.
Process Benefits
There are several benefits to our process, including environmentally friendly nature, waste minimization, large treatment capability, and year-round operation.
Environmentally Friendly Nature
Our technology eliminates the need for land disposal or incineration, exceeding the most stringent clean-up criteria. The closed system design reduces atmospheric emissions to a fraction of that of direct fired systems. Hydrocarbons are separated and recovered, not burned and released into the atmosphere as greenhouse gases.
Waste Minimization / Recycling
The non-destructive nature of the process allows wastes to be converted into useful products. Our technology can produce a commercially valuable product while reducing and de-listing a hazardous waste stream.
Large Treatment Capability
Any compound, organic or inorganic, that can be converted to a higher volatile substance at our system’s boiling point can be removed from a stable matrix and further recycled.
24-Hour Year-Round Operation
Our plants are designed to operate about 90% of the time within a 24-hour, year-round schedule.
Design Benefits
RLC Technologies has built and delivered over 30 indirect fired thermal desorption plants to job sites around the world. With a focus on safety and a sophisticated design and control system, our thermal desorption plants have proven to be safe and reliable time and time again.
Custom Design
Our plants are custom-designed for each specific application, depending on the customer’s specific needs and type of contaminated material. Each one of the ATDU plants we build are constantly improving in design and performance to provide the very best for our customers.
Low Maintenance Design
Our custom design enables our equipment to operate successfully with minimum required maintenance. Abrasive materials, like those found in drill cuttings and other wastes, do not cause wear from friction as they do in other thermal treatment systems.
Mobility / Emergency Response
Our plants can be easily placed on trailers and transported to remote sites. Quick electrical disconnects allow easy mobilization and demobilization.
Worldwide on-Site Assistance
We want our clients to be able to operate properly and effectively. Therefore, our experienced specialists provide on-site training and worldwide assistance during the plant set-up and all operations thereafter. We are ready to provide our clients with spare parts, technical data, and consultations as needed.
Financial Benefits
RLC Technologies offers competitive pricing, a full-year warranty, and suitable payment terms to meet the needs of our clients all across the world.
Competitive Price
We structure our business so we can offer our clients internationally competitive prices.
Cost Effectiveness
We help our clients operate in the most cost-effective way by transforming waste into a product that has commercial value, low-maintenance design, high-quality components, stable and reliable operations, and mobility.
De-Listing of Waste While Recovering Oil
D, F & K wastes can be processed through our ATDU and meet UTS, allowing for disposal in a non-hazardous or industrial landfill.
One Year Full Warranty
We offer One (1) year warranties on all of our equipment.
Suitable Payment Terms
We are open to using different INCOTERMS terms when pricing our equipment. We are also willing to discuss different payment terms with our clients. All transactions are facilitated via Ex-Im financing for international sales.
Safety Benefits
Our equipment is completed with a state-of-the-art reliable control and safety system which assures stable operations and virtually eliminates the risk of accidents.
RLC Technologies ATDU systems have been operating safely for more then twenty years. Our FM/NFPA compliant combustion system have been certified by CE/ATEX and as well as Safety Integral Level 2 (SIL 2). CE/ATEX and/or SIL certification are available with any of our ATDU products. Our TDU facilities are also designed per NEC Class 1 Division 1 or 2 and/or ATEX or IEC Zone 1 or 2 or IEC explosion proof for safe operation in Hazardous Area locations. In addition to certifications, the ATDU control system is designed with multiple redundant interlocks to ensure safe operation.
Uptime Efficiency Benefits
We help our clients have more productive uptime with less maintenance or stalled work due to repairs. Unlike most competing technologies, we guarantee a 90+% uptime.
With a high throughput at a low operating cost, clients are able to operate their job sites properly and efficiently.
Scalability
Our systems are built to be expanded or added onto depending on production needs. Since the system’s components are modular, they can easily be enlarged as your operations expand.
Due to the modular nature of our TDU equipment, existing systems can be expanded to increase processing capacity as demand increases. Further to this cost savings can be realized as there are many common components which can be shared between systems. Furthermore, a smaller ATDU system can easily be upgraded to a unit with a higher production capacity.
