Étude expérimentale de la dispersion active d'un polluant hydrocarboné en milieu poreux hétérogène
[Active dispersion of a hydrocarbon pollutant in heterogeneous porous media: experimental study]
Comptes Rendus. Mécanique, Volume 334 (2006) no. 1, pp. 58-67.

This study deals with Non Aqueous Phase Liquid (NAPL) dissolution in subsurface water in order to predict the pollutant plume development and to optimize remediation processes. An experimental study of NAPL dissolution in porous media is presented. Local water saturation and effluent pollutant concentration measurements are presented for several kinds of porous media. Experimental results show clearly the influence of microscopic and/or macroscopic heterogeneities of the porous media and the distribution of the pollutant on the active dispersion of the NAPL. The NAPL dissolution occurs in several steps which highlights the existence of non-local equilibrium related to the heterogeneity of the porous media.

Cette Note se situe dans le cadre des études concernant la dissolution d'un polluant hydrocarboné dans des eaux souterraines dans le but de modéliser le développement de panaches de pollution et d'optimiser des procédés de dépollution. Une étude expérimentale de dissolution d'un polluant dans des milieux poreux de différents types est présentée. Des mesures de saturation locale ainsi que de la concentration en polluant dans les effluents sont réalisées au cours de l'expérience. Les résultats expérimentaux mettent en évidence l'importance déterminante des hétérogénéités microscopiques et/ou macroscopiques du milieu poreux et de la distribution du polluant lors de la dispersion active du NAPL. La dissolution du polluant s'effectue en plusieurs étapes qui mettent en évidence des conditions de non équilibre local liées à l'hétérogénéité du milieu poreux.
