Evaporation of a volatile organic compound in a hygroscopic soil - influence of the airflow and its VOC vapour saturation

Abstract : This article presents an experimental and theoretical study of VOC volatilization in soil during a decontamination process by vapour extraction or venting. A phase change law is proposed in the case of a sandy-silty soil when the convective gaseous phase is vapour-charged. A simple experimental method for analyzing the phase change is presented. Finally, an efficiency coefficient is introduced to quantify the contribution of airflow velocity on venting.
