    • An in situ thermal desorption (ISTD) soil remediation system (20) may be used to remove or reduce contamination within soil (24). Heat may be transferred to the soil (24) from resistively heated, bare metal heater elements (56). The heater elements (56) may be placed directly within the soil (24). Alternately, the heater elements (56) may be suspended within casings (60). The heater elements (56) may be conductive heaters, or the heater elements may be radiative heater elements. The ISTD soil remediation system (20) may include temperature-resistant, chemical resistant, flexible conduits that transport off-gas removed from the ground to a treatment facility (34). 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 (34) through a manifold and piping made of polymeric material.
    • 原位热解吸(ISTD)土壤修复系统(20)可用于去除或减少土壤内的污染(24)。 热可以从电阻加热的裸金属加热器元件(56)转移到土壤(24)。 加热器元件(56)可以直接放置在土壤(24)内。 或者,加热器元件(56)可以悬挂在壳体(60)内。 加热器元件(56)可以是导热加热器,或者加热器元件可以是辐射加热器元件。 ISTD土壤修复系统(20)可以包括将从地面移除的废气输送到处理设施(34)的耐温,耐化学腐蚀的柔性管道。 废气在管道内的停留时间可能足以允许废气冷却,使得废气可以通过聚合物和由聚合材料制成的管道传递到处理设备(34)。

    • 原位热解吸(ISTD)土壤修复系统(20)可用于去除或减少土壤中的污染(24)。 热量可以从电阻加热的裸露金属加热器元件(56)传递到土壤(24)。 加热器元件(56)可以直接放置在土壤(24)内。 可选地,加热器元件(56)可以悬挂在壳体(60)内。 加热器元件(56)可以是导电加热器,或者加热器元件可以是辐射加热器元件。 ISTD土壤修复系统(20)可能包括耐热,耐化学腐蚀的柔性管道,将从地下排出的废气输送到处理设施(34)。 废气在管道内的停留时间可能足以允许废气冷却,使得废气可以通过歧管和由聚合物材料制成的管道传递到处理设施(34)。
