Dépollution des sols : étude expérimentale du traitement par venting

Abstract : The aromatic hydrocarbons (BTEX) and the alkanes are the majority components of the fuels. The period of time passed in the ground induced them different behaviors in the moment of depollution. The goal of this study was initially to develop a simple experimental technique and a reliable exploitation of the obtained results. In particular, we studied the effect of ageing of toluene (BTEX) and heptane (alkanes) on the depollution process by venting. In the mean time, we built a simple mathematical model based only on the physical processes which take place during the ageing and depollution period. From an assumption of homogeneity of the soil and equilibrium between the existence phases of pollutants, the model enabled us to evaluate the output of the current systems and to give the forecast of the progress of venting process.
