Abstract

Soil remed action process for heating soil in a pile (136) using heat injection wells (142).

Claims (19)

1. A method, comprising:
placing soil in a plurality of treatment sites;
treating soil in the plurality of treatment sites using equipment in a central treatment facility;
removing soil from the plurality of treatment sites; and wherein placing soil in each of the plurality of treatment sites, treating soil in each of the plurality of treatment sites, and removing soil from each of the plurality of treatment sites is coordinated such that equipment in the central treatment facility operates substantially continuously.
2. The method of claim 1, wherein placing soil in a plurality of treatment sites comprises placing soil in a pile in at least one of the treatment sites.
3. The method of claim 1 or 2, wherein placing soil in a plurality of treatment sites comprises at least partially containing soil in at least one of the treatment sites.
4. The method of any one of claims 1-3, wherein placing soil comprises placing soil on a liner on a ground surface.
5. The method of any one of claims 1-3, wherein placing soil comprises placing soil on a porous layer, wherein the porous layer is positioned over a liner on a ground surface.
6. The method of any one of claims 1-3, wherein placing soil comprises placing soil on a porous layer, wherein the porous layer is positioned over a liner on a ground surface, and wherein a collection conduit is positioned within the porous layer.
7. The method of any one of claims 1-6, wherein placing soil comprises covering the soil.
8. The method of any one of claims 1-7, wherein placing soil comprises positioning a cover over the soil and at least partially sealing the cover to a surface.
9. The method of any one of claims 1-8, wherein treating soil comprises applying a vacuum to soil in at least one of the treatment sites.
10. The method of any one of claims 1-9, wherein treating soil comprises heating the soil radiatively.
11. The method of any one of claims 1-10, wherein treating soil comprises heating the soil conductively.
12. The method of any one of claims 1-11, wherein treating soil comprises introducing an oxidizing agent into the soil.
13. The method of any one of claims 1-12, wherein treating soil comprises allowing contaminants within the soil to undergo pyrolysis.
14. The method of any one of claims 1-13, wherein treating soil comprises raising a temperature of the soil to at least a vaporization temperature of water.
15. The method of any one of claims 1-14, wherein treating soil comprises extracting vapors from the soil.
16. The method of any one of claims 1-15, wherein treating soil comprises removing fluid from the soil.
17. The method of any one of claims 1-16, wherein treating soil comprises injecting fluid into the soil.
18. The method of any one of claims 1-17, wherein off-gas from one of the treatment sites is directed into another one of the treatment sites.
19. The method of any one of claims 1-18, wherein soil in the plurality of treatment sites is treated sequentially.
