Abstract

Air stripping as a means of soil remediation has gained popularity in recent years. In this in situ process, clean air a injected into the contaminated soil zone to volatilize and strip the contaminants which are then removed by the carrier gas. The process has been found to be effective especially for treating the vadose zone of the soil contaminated with volatile and semivolatile organics. Nitrogen adsorption/ desorption experiments in this study were performed on a soil sample to establish its desorption characteristics. A field-scale model for the air stripping process has been developed to simulate the removal of semivolatile hydrocarbons. The numerical results show that the interphase contaminant transport from the sorbed to the vapor phase plays a dominant role in influencing the process effectiveness.
