Patent

CA 2289080

A method is provided to remove volatile liquid contaminates from a contaminated volume of earth, the contaminated volume lying above a non-contaminated layer of earth, the method including the step of heating the non-contaminated layer until the temperature of a substantial portion of the non-contaminated layer that is contiguous with the contaminated layer is at least the boiling point temperature of contaminated liquids so as to prevent vaporized contaminants to move downwards from the contaminated layer of earth.

L'invention concerne un procédé permettant d'éliminer des contaminants liquides volatils d'un volume de terre contaminé situé sur une couche de terre non contaminée. Ce procédé consiste à chauffer la couche non contaminée jusqu'à ce que la température d'une partie substantielle de cette couche, contiguë à la couche contaminée, atteigne au moins la température correspondant au point d'ébullition des liquides contaminés et ce, de manière à empêcher les contaminants volatils de migrer vers le bas à partir de la couche de terre contaminée.
