Experimental investigation of hot water and cosolvent flushing for remediation of NAPL-contaminated aquifers
Technical Report
·
OSTI ID:56465
Pump and treat is the most commonly used method for removing contaminants from groundwater but has proven ineffective in the case of nonaqueous phase liquids (NAPLs). Two methods that have been used to enhance recovery of crude oil, hot water and alcohol flooding, were investigated in the laboratory as a means of enhancing the dissolution and recovery of NAPLs in groundwater. A ubiquitous NAPL, tetrachloroethylene (PCE), was chosen for recovery in this investigation. The PCE/methanol/water system was studied to evaluate the effect of methanol concentration on interfacial tension, equilibrium phase composition, and phase density.
