Definitions

  • the system of the present invention does not use heated air as the medium for transporting heat to the contaminated soil, and thus does not suffer this shortcoming.
  • Heated air commingles with the contaminated offgas extracted from the contaminated soil, and therefore must also be treated.
  • the system of the present invention does not use heated air as the medium for transporting heat to the contaminated soil, and thus does not suffer this shortcoming.
  • the system of the present invention produces a substantially lesser volume of exhaust air.
  • Elevated temperatures may even be employed depending on the temperature limitations of the multi-functional perforated pipes and heating elements and the covering.
  • a multi-functional perforated pipes and covering which can withstand extremely high temperatures, i.e., from about 2,000 up to 3,000 degrees F.
  • a corresponding extremely high temperature heat can be employed.
  • the first functional can be imparted to the contaminated soil, namely, volatilizing the contaminants located within the contaminated soil thereby producing a pressurized, contaminated vapor.
  • the contaminated soil after the contaminated vapor is removed from within the remediation cell, typically has an average moisture level of not more than about 5 % by weight, preferably not more than about 4 % by weight, more preferably not more than about 2% by weight, and most preferably not more than about 1% by weight.
  • Control of heating using electrical current can be accomplished automatically across zones within the cell in a much more standardized approach to contaminant remediation.
  • the invention described herein is not limited in remediation cell depth, length and width. Forced air heating, on the other hand, is constrained by the extent to which it can affect the remediation process and the limitations imposed by the necessity of routing the high volumes of off-gases. Conversely, the subject method and system will remediate the soil in the remediation cell to a level well beyond that which can be achieve using driven forced air.
  • the electric heating elements are inserted into the multi-functional perforated pipes and connected to the power panels.
  • the multi-functional perforated pipes directly as the heating elements, the multi-functional perforated pipes are connected to the power panels.

Abstract

L'invention concerne un système et un procédé de traitement de sols contaminés. Ce système comprend une cellule de traitement de sols contenant un sol contaminé, ainsi qu'une pluralité de tuyaux perforés multi-fonctionnels situés dans le sol contaminé. Ces tuyaux perforés multi-fonctionnels fonctionnent comme (a) des éléments de chauffage servant à introduire de la chaleur dans le sol contaminé pour permettre la volatilisation des contaminants se trouvant dans le sol contaminé sans utiliser d'air forcé entraîné mécaniquement, ce qui produit une vapeur contaminée, et (b) des canaux d'écoulement destinés à éliminer cette vapeur contaminée de l'intérieur de la cellule de traitement de sols. Un couvercle haute température, situé au niveau de la cellule de traitement de sols, forme une chambre sur ladite cellule qui reçoit et recueille dans cette chambre la vapeur contaminée s'échappant des tuyaux perforés multi-fonctionnels. Des moyens permettant de recueillir et/ou détruire les contaminants des vapeurs contaminées recueillies dans la chambre de stockage peuvent également être utilisés conjointement avec la cellule de traitement de sols.
