摘要： An in situ method for removal of contaminants from soil imposes a vacuum on the soil through perforated heater wells that are positioned in the soil. The heater wells heat the soil to elevated temperatures by thermal conduction. The heater wells are permeable to vapors which emanate from the soil when heated and which are drawn towards the heater wells by the imposed vacuum. An impermeable flexible sheeting on the soil surface reduces the amount of air that is being pulled into the heater well from the atmosphere. A thermal insulator covers the soil surface and reduces heat losses from the soil surface. The heater wells are connected to a vacuum manifold for collection of vapors. A heat front moves away from the heater wells through the soil by thermal conduction, and the superposition of heat from a plurality of heater wells results in a more uniform temperature rise throughout the well pattern. Soil contaminants are removed by vaporization, in situ thermal decomposition, oxidation, combustion, and by steam distillation. Both the presence of water vapor and the low pressure results in vaporization of the contaminants at temperatures well below their normal boiling points. Moreover, the heater wells and the nearby soil are extremely hot and most contaminants drawn into the wells will decompose with a residence time of the order of seconds. The heater well can also be packed with a catalyst that accelerates high temperature decomposition into simpler molecules. Water vapor and remaining contaminants may be incinerated in line or may be collected in a cold trap upstream from the vacuum pump.
摘要翻译：从土壤中去除污染物的原位方法通过位于土壤中的穿孔加热井在土壤上施加真空。加热井通过热传导将土壤加热到升高的温度。加热井对加热时从土壤发出的蒸气是可渗透的，并通过施加的真空向加热器井拉出。在土壤表面上的不透水柔性薄板减少了从大气中吸入加热器的空气量。绝热体覆盖土壤表面，减少土壤表面的热量损失。加热器井连接到用于收集蒸汽的真空歧管。热源通过热传导离开加热器井通过土壤，并且来自多个加热井的热量的叠加导致整个井模式中更均匀的温度升高。通过蒸发，原位热分解，氧化，燃烧和蒸汽蒸馏除去土壤污染物。水蒸汽的存在和低压都导致污染物在远低于其正常沸点的温度下蒸发。此外，加热器井和附近的土壤是非常热的，并且大部分被吸入井中的污染物将以几秒的停留时间分解。加热器井也可以填充催化剂，将催化剂高温分解加速成更简单的分子。水蒸汽和剩余的污染物可以排成一行，或者可以被收集在真空泵上游的冷阱中。

摘要： An in situ thermal desorption soil remediation system may be used to remove contamination from soil. Heat may be applied to the soil by metallic strip heaters that have large cross sectional areas as compared to conventional heater elements. The strip heaters may be made of stainless steel. Large cross sectional areas of the strip heaters allow for large areas of thermal contact between the strip heaters and the soil being treated. Casings may not be needed between the strip heaters and the soil. The operating temperature of the strip heaters is self-regulating. As the temperature of a strip heater increases, the electrical resistance of the strip heater also increases. The increase in resistance causes a decrease in the power dissipation of the strip heater. The decrease in power dissipation as temperature increases allows a steady state heater strip temperature to be attained during use.

摘要： An in situ soil remediation system may be used to remove or reduce levels of mercury contamination within soil. The soil remediation system may also remove or reduce levels of other contaminants within the soil. Mercury may be vaporized within the soil by a heating system. The vaporized mercury may be removed from the soil by a vacuum system. The vaporized mercury may pass through heated risers that elevate the vaporized mercury. After the vaporized mercury passes from the heated risers, the vaporized mercury may be allowed to cool, condense, and flow downward to a treatment facility. Removing mercury from the soil as a vapor may provide an economical, safe, and efficient way to remediate mercury contaminated soil.

摘要： An in situ thermal desorption (ISTD) soil remediation system may be used to remove or reduce contamination within soil. Heat may be transferred to the soil from resistively heated, bare metal heater elements. The heater elements may be placed directly within the soil. Alternately, the heater elements may be suspended within casings. The heater elements may be conductive heaters, or the heater elements may be radiative heater elements. The ISTD soil remediation system may include temperature-resistant, chemical resistant, flexible conduits that transport off-gas removed from the ground to a treatment facility. A residence time of off-gas within the conduits may be sufficient to allow the off-gas to cool so that the off-gas may pass to a treatment facility through a manifold and piping made of polymeric material.

摘要： A perforated casing may be placed within contaminated soil. Perforations within the casing may be covered during insertion of the casing into the ground. Covering the perforations may inhibit plugging of the perforations during installation. Covering the perforations may also inhibit worker exposure to contaminant dust or vapors during insertion of the casing into the ground. The covering for the perforations in a casing may be plugs that are placed or formed in the casing perforations. Alternately, the covering for the perforations may be a sleeve placed adjacent to the perforations. After installation of the casing, heating or chemically treating the perforation coverings may remove the coverings and allow insertion or removal of fluids and vapor through the casing.

摘要： A method is provided to remove contaminants from contaminated soil. The method may include withdrawing vapors from a vapor extraction well, estimating the amount of water vapor removed from the contaminated soil in the vapors being withdrawn from the vapor extraction well, and applying heat to the contaminated soil from a plurality of heater wells at a rate not greater than that which would vaporize the estimated amount of water vapor. The permeability of the soil may thereby increase by the application of heat. Six or more heat injection wells may be provided for each vapor extraction well, and the heat injection wells may be placed and energized in a regular pattern around the vapor extraction well, which may include multiple rings of heaters around each vapor extraction well.
