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, ...

  • Application of thermal desorption to occupational exposure monitoring

    Occupational hygiene, in its broadest sense, is the recognition, evaluation and control of health hazards arising from work – a trained hygienist needs to understand a range of subjects from health and safety legislation through to toxicology, hazardous substances, physical agents, exposure assessment and exposure control strategies. To some extent, occupational hygiene is relevant in all ...

  • Contaminant removal from dry and wet sands by thermal desorption

    Infrared heating was used to determine the effects of temperature and moisture on the removal of selected organic compounds from contaminated sand matrices. Quartz sand was used as a chemically inert surrogate for soil to isolate the heat transfer and mass transfer effects without any chemical contribution from soil. The selected organic contaminants were 3-nitrobenzene sulphonic acid, sodium ...

  • 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 ...

  • In-Pile thermal desorption for treatment of Dioxin-Contaminated soil in Japan

    Abstract A demonstration of thermal treatment of dioxin-contaminated soil was completed in Japan, under the sponsorship of the Japan Ministry of the Environment. TerraTherm’s proprietary In-Pile Thermal Desorption process was demonstrated to successfully treat the soil to the required standard of 1,000 picograms of 2,3,7,8-tetrachlorodibenzodioxin (TCDD) toxic equivalents (TEQ) per ...

  • 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 ...

  • News on Air 2014, Volume 1: Thermal Desorption - Selecting Your Adsorbent Tube

    Thermal Desorption - which tube and which adsorbent do I need? Supelco produces a comprehensive selection of adsorbent tubes. Selection of the proper adsorbent(s) is critical to achieving the best results for a thermal desorption application. An ideal adsorbent tube, such as Carbotrap tubes, will trap and retain compounds of interest for the entire sampling period, then allow total analyte ...

  • 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 ...

  • Carbotrap Carbon Black: An Excellent Adsorbent for Solvent or Thermal Desorption/GC Analyses of Airborne Organic Compounds

    Carbotrap adsorbent traps and releases a wider range of airborne organic compounds than Tenax GC or Amberlite XAD-2 resin. Compounds adsorbed by Carabotrap adsorbent can be completely recovered through either solvent or thermal desorption. Carbon disulfide, a highly effective desorbing solvent, degrades Tenax GC and Amberlite XAD-2, forcing you to use potentially less effective desorbing ...

  • Ex Situ Thermal Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatments is that they generally require shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to screen, homogenize, and continuously mix the soils. Ex situ processes, however, require excavation of soils leading to increased costs and engineering for equipment, possible permitting, and materials handling worker ...

  • Combining thermal treatment with MNA at a brownfield DNAPL site

    Abstract A heavily contaminated Brownfields site in New York was remediated and redeveloped using a combination of In-Situ Thermal Desorption and Monitored Natural Attenuation. Four source areas were addressed by the thermal technology, and groundwater beneath the site is undergoing natural attenuation. Approximately 86,000 lbs of volatile organics were extracted and treated on-site. The ...

  • In-Situ thermal treatment of MGP waste and creosote

    Abstract: Remediation of coal tar at former Manufactured Gas Plant (MGP) sites, and creosote associated with wood preservative sites is challenging due to the viscous nature of the dense non-aqueous phase liquid (DNAPL) and the modest solubility and vapor pressure of the contaminants of concern (COCs). DNAPL seepage into surface water bodies, as well as groundwater plumes formed by the most ...

  • Cuyama Case Study (Ex Situ Gas Thermal Remediation(GTR™))

    Ex Situ Thermal Desorption was used to successfully treat TPH-d and TPH-g from a former AST spill site in the agricultural zone in Central California. Affected soils were excavated and then placed “in a pile”, and Gas Thermal Remediation (GTR©) horizontal wells were placed into the pile during its three day construction. The piled soils represented mixed sands and high TOC soils, ...
