    EXECUTIVE SUMMARY Systematic guidance information on various currently available thermal desorption systems is not readily available. The purpose of this Application Guide is to provide (1) technical information on, design and performance characteristics, cost, associated regulatory compliance issues, and contracting strategies for deploying thermal desorption systems, and (2) to establish a ...

  • Thermal Desorption Unit - Overview, Types and Applications

    Thermal desorption is basically a remediation technique heavily used to clean contaminated soils, sludge’s etc. This technique uses heat to vaporize the contaminants, and works only for volatile contaminants. These include typically organic wastes composed of hydrocarbons, such as coal tar wastes, chlorinated solvents, oil refining wastes, fuels, pesticides, and a lot other. In the process, ...

  • Ozone precursor analysis using a thermal desorption-GC System

    In the United States, the Clean Air Act of 1970 gave the U.S. Environmental Protection Agency (EPA) responsibility for maintaining clean air for health and welfare. Six parameters are measured routinely in ambient air: SOx, NOx, PM10 (particulate matter less than 10 microns), Pb, CO and ozone. In the 1990 Clean Air Act Amendments, Title 1 expanded the measurements in air to include volatile ...

  • Thermal Desorption-GC/MS Analysis of polycyclic aromatic hydrocarbons on fine particulates in air

    Polycyclic aromatic hydrocarbons (PAHs) are commonly found throughout the environment in soil, water and adsorbed to fine particulate matter in air. Of the 16 common PAHs, 7 have been classified as animal carcinogens by the International Agency for Research on Cancer (IARC). Resulting from this classification, PAHs are monitored and regulated in the environment. Analysis of PAHs in soil and water ...

  • On-Site Thermal Desorption of PCP- and Dioxin-Contaminated Soil at the Coleman-Evans Wood Preserving Site, Whitehouse, Florida, USA

    ABSTRACT Roy F. Weston, Inc. (WESTON®) has designed an indirect thermal desorption process (known as the LT3-HT) to treat solids and sludges contaminated with hazardous and toxic materials. The LT3-HT is a high-temperature, high-capacity thermal desorption system designed for treatment of semivolatile and volatile organic contaminants that require high treatment temperatures. The LT3-HT ...

  • Environmental impacts of aquifer thermal energy storage investigated by field and laboratory experiments

    Aquifer thermal energy storage (ATES) uses groundwater to store energy for heating or cooling purposes in the built environment. This paper presents field and laboratory results aiming to elucidate the effects that ATES operation may have on chemical groundwater quality. Field data from an ATES site in the south of the Netherlands show that ATES results in chemical quality perturbations due to ...

  • Case study - Mobile remediation system

    OVERVIEW A large consulting and contracting firm owns and operates several ex-situ Thermal Desorption Units (TDUs). Each single-load Thermal Desorption Unit has the capacity of desorbing 15 tons of soil per hour at a temperature of 400°F - 900°F. These Thermal Desorber Units have been designed to operate on both chlorinated and non-chlorinated RCRA, CERCLA, and private industry ...

  • Gaseous release in LiNH2–MgH2 systems

    Hydrogen is considered a safe and clean alternative to fossil fuels. Hydrogen storage is currently obtained by compressing the gas at high pressure. Researchers are currently attempting to tackle safety and energy density issues by locking hydrogen into solids, packing large quantities into small volumes. However, most of the known solids (i.e. intermetallics) show very low gravimetric density, ...

  • Common Treatment Train for Nonhalogenated SVOCs

    A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for nonhalogenated SVOCs is illustrated below. A thermally enhanced soil vapor extraction system is used to pull SVOC vapor from the contaminated soil. Electrodes are installed in the contamination zone to enhance the desorption of SVOCs from the contaminated soil. The ...

  • TVOC measurement for LEED/green building evaluation

    Total Volatile Organic Compounds (TVOC) may be evaluated when building designers/managers are pursuing the Leadership in Energy and Environmental Design Green Building Rating System for New Construction (LEED-NC) EQ Credit 3.2. The latest LEED-NC guidance document specifies that the maximum allowed concentration of TVOC measured in a building (post construction, pre-occupancy) is 500 µg/m3; the ...


  • Common Treatment Technologies for Nonhalogenated VOCs in Soil, Sediment and Sludge

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

  • Oil and metal recovery from mill scale and grinding swarf for the metal industry - case study
