Thermal Phase Separation (TPS) Technology
The patented TPS technology is a unique example of a group of technologies referred to as Low Temperature Indirect Thermal Desorption
The system was invented by the management team of WMT and has been operating around the world for over 20 years and has been operating in China since 2010.
The TPS is capable of safely extracting all hydrocarbon contaminants from soil and sludge using indirectly applied heat in an enclosed extraction chamber. The hydrocarbons are heated to the point of volatilization and are removed from the chamber where they are condensed and separated for final disposition. Chlorinated organic hydrocarbons such as PCBs , dioxins, DDT and PAH are carefully contained for 3rd party destruction while non-hazardous hydrocarbons such as diesel or crude oil are filtered and recycled. Unlike incineration, the entire process is done without producing any harmful air emissions as the contaminants never come into contact with the flame from the heat source. As a result the system is much more readily approved by regulators for mobile deployment, accepted by the public and produces only a fraction of the greenhouse gases commonly associated with thermal treatment of hazardous soils.
A basic TPS system consists of 4 components designed for transport as standard intermodal units to reduce cost and transport complications:
- Control Unit
- Extraction Unit
- NCG Management Unit
- Condensate Management Unit
- Cooler Unit
TPS systems are available in small or large capacity configurations. A basic TPS 2EC system can treat up to a 55 metric tonnes of material per day while a TPS 3EC system has a capacity of 144 metric tonnes with an operational crew of only 5 personnel. Production with either system can be can be doubled or tripled through the addition of one or two Extraction Chambers while requiring minimal no additional personnel.
TPS is recommended for larger, complex remediation sites where directly heated systems are not acceptable and contaminants such as PCB, pesticides and dioxins represent significant hazards to contractors, operators and the environment.
