  • Application Guide for Thermal Desorption Systems

    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, ...

  • Mississauga Case Study (In Situ Gas Thermal Remediation (GTR™))

    In Situ Thermal Desorption in conjunction with soil vapor extraction was used to remove volatile organic compounds which contaminated the groundwater and saturated soil areas of a former metal fabricating facility in Ontario, Canada. The site had VOCs detected above the Canadian water standard in various monitoring well locations.  The remediation goal was achieved in 84 days and saw a 98% ...

  • 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, ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Remediation of hydrocarbon contaminants from oil lagoons and refinery waste - case study

    In 2007 econ delivered an indirectly heated thermal desorption plant to a client in Kuwait. The plant is de-signed to treat various types of waste with hydrocarbon contaminant content. In particular refinery waste, oil lagoons and down hole drilling waste. The aim is to recover the waste hydrocarbons from the soil/sand and remediate the lagoons of their contaminants.  Due to the natural ...

  • Clean dirt, no doubt! (Eh?)…Canada’s Nelson Environmental Remediation treats its business with heat and home grown values…

    Clean Dirt, No Doubt! Indeed. With a distinctive Northern Canadian accent and a complimentary penchant for hard work, these words resound in the minds of brothers Darryl and Warren Nelson, President and Vice- President respectively, of their contaminated soil-cleaning business, Nelson Environmental Remediation Ltd. (NER). Clean Dirt, No Doubt! is, after all, the Company’s tagline and guiding ...

  • 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 ...

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

    Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with halogenated 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 analysis ...

  • 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 ...

  • Soil baked to clean up contamination...

    Can an old drill site be cleaned up without adding truckloads of contaminated soil to the landfill? Chevron Canada will be using a technology called thermal desorption to clean up a site located 13 kilometres southwest of Pincher Creek. Leif Sollid, spokesman for Chevron, who is the operator of the site, said they considered two options for the clean up. The soil is classified as a non-dangerous ...
