%X In order to study the Vapor Extraction Technology that can be applied to China, on the basis of mechanism analysis of Vapor Extraction Technology for oil-contaminated soil, a simplified and practical contaminant removal model to simulate the soil remediation time was presented. With the typical unsaturated soils in North of China, the effects of the vapor flow rate, soil water content and quality on the remediation process were studied. The results showed that the best value of flow velocity was existed, and water content had different influence on different kinds of soil, for silty soil, the efficiency of remediation enhanced with water content increase, but there was a reverse result for clayey soil. Through one-dimension soil column experiments, the results showed that these factors had different effects on remediation time. The research using the soil column apparatus show that the predicted results were validated and the applied conditions of this model were qualified.
