Outline of Final Research Achievements

This study has discussed that effectiveness of injecting fluids with temperature controlled into the contaminated soil by organic solvents like fuels and residual organic solvent in the pore structure was analyzed by image analysis using X-ray CT scanner. In this study, three different temperature conditions were prepared on the temperature T1 for soil and T2 for injection fluids such as T1=T2, T1<T2 and T1>T2. In fact, when T1 was 60oC and T2 was 20oC, the organic solvent in the pore structure was collected well because capillarity of injection fluid was restricted by low temperature condition and besides, local path of organic solvent was not formed under this temperature condition.
