ESMI owns portable equipment that is used for the low temperature thermal desorption (LTTD) of contaminated soils at the site of generation. The high capacity portable plant is manufactured by SPI, a division of ASTEC Systems of Chattanooga, Tennessee. SPI equipment is highly regarded as the
Thermal Desorption Plant Thermal desorption is an advanced treatment for hazardous waste streams. This process utilises heat to increase the volatility of contaminants so that they can be separated from waste materials such as sludge or filter cake.
The GERSTEL Thermal Desorption Unit (TDU) was developed as a dedicated instrument for use with GERSTEL Twister stir bars, but due to continued system development, it now has 6 additional sample introduction techniques for GC and GC/MS analysis. The TDU is used with the GERSTEL Cooled Injection System (CIS) on a GC or GC/MS system to enable ultra-trace analysis of a wide range of …
The end goal of direct fired thermal desorption is to remediate soil so that it meets applicable remediation criteria, and is thus available for beneficial re-use.Success requires the combined experience of the NELSON team perfected on numerous large scale projects across the globe.
Plant Description. Excavated soils require soil processing before thermal treatment. A common thermal desorption design is the rotary dryer, rotary dryers are indirect or direct-fired horizontal cylinders. The cylinder is normally inclined and rotated to move the contaminated soil along the cylinder.
OverviewTarmac: A Plant System Equipment Manufacturer. For more than 20 years, Tarmac International, Inc. has built complete thermal soil remediation plants that are in use around the world. Our thermal soil remediation plants have production rates ranging from 5 to …

Description of Direct Thermal Desorption Mobile Plant (DTD) Mobile unit for direct thermal desorption (DTD) Whereas indirect thermal desorption (IDT) can be applied to a large range of pollutants in soil, direct thermal desorption (DTD) is especially used for the treatment of soils contaminated with hydrocarbons and/or other pollutants
About Thermal Desorption Plant The plant has been used to treat contaminated soil with difficult pollutants. It consists of a rotation drum and indirect introduction of heat. The gas is burned in an after-burning unit at high temperature. Exhaust gases are used for pre-heating and drying. - Plant has been in use since 2002. - It is transportable.
Astec direct-fired thermal desorption plants have effectively treated materials from many different manufactured gas plant (MGP) sites. Also known as TOWN GAS WORKS, these plants used a coal gasification process to manufacture fuel gas for lighting and heating. The by-product produced was a gas-processing residue.
Envirogreen Technologies Ltd. provides cost-effective, environmentally responsible solutions for the treatment and disposal of contaminated materials and soils. As the only permitted Hazardous Waste thermal treatment facility in British Columbia, our expert team uses thermal desorption remediation technology to conclusively remove contaminates.
Thermal desorption is generally an exsitu process designed to separate organic compounds from soils, sediments and sludges. (EPA 1992a, 3) The thermal desorotion process transfers heat to the solid waste particles in order to volatilize the contaminants. Air, combustion gas, or inert gas is used to
• Thermal desorption chamber ~ One of the primary regulatory distinctions between a thermal desorber and an incinerator is the degree to which the desorber is direct-flame fired. Thermal desorbers are generally indirectly heated. For example, treatment
Overview[PDF]A Citizen’s Guide to . Thermal Desorption. What Is Thermal Desorption? Thermal desorption removes organic contaminants from soil, sludge or sediment by heating them in a . machine called a “thermal desorber” to evaporate the contaminants. Evaporation changes the contaminants into vapors (gases) and separates them from the solid material.

Thermal Desorption solves environmental remediation problems by using either direct or indirect heat to vaporize organic contaminants from soil, sludge, or sediment. Through this process, contaminants go from a liquid to a vapor phase and are separated from the solid material.
Jan 29, 2013· Thermal desorption is a remediation method used to clean contaminated soils. This method uses heat to vaporize the contaminants, and as such only works for volatile contaminants. These include mostly organic wastes composed of hydrocarbons, such as oil refining wastes, coal tar wastes, wood-treating wastes, creosotes, chlorinated solvents, fuels, PCBs, mixed wastes, synthetic rubber …

In this study, the thermal desorption process was used to treat a mercury-contaminated soils in Taipei. A series of bench or pilot plant experiments were also performed the optimized operation condition. The results showed that the concentrations of residual mercury in all treated soils were below 2 mg/kg, some even lower than 0.05 mg/kg.
