Abstract
A method for remediating land contaminated by a combustible material, in particular, land contaminated with non-aqueous phase liquids (NAPLs), which includes the steps of locating a subterranean volume of combustible material such as a DNAPL in land to be remediated, and igniting the combustible material to combust the material and thereby remediate the land. By monitoring combustion of the material, combustion may be optimised by, for example, supplying an oxidant or a combustion suppressant.
Claims18
A method of remediating land contaminated with a combustible material, the method comprising the steps of:
- locating a subterranean volume of combustible material in land to be remediated, wherein the land defines a porous matrix and the combustible material is present in the porous matrix,
- igniting the combustible material to combust the combustible material in a smouldering combustion process by applying heat to the combustible material with an ignition device followed by supplying an oxidant to the combustible material;
- and
- when the smouldering combustion process is established, deactivating the ignition device and thereby remediating the land.
