    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 for heat injection into a subterranean formation is provided. The method utilizes flameless combustion and a gas fired heater having an electrical heated surface for ignition of the gas. The absence of a flame eliminates the flame as a radiant heat source and results in a more even temperature distribution throughout the length of the burner. Flameless combustion is accomplished by preheating the fuel and the combustion air to a temperature above the autoignition temperature of the mixture. Preheating hydrocarbon fuel requires the inclusion of a carbon formation suppressant such as carbon dioxide or steam to prevent carbon formation.
