Modeling BTEX Multiphase Partitioning with Soil Vapor Extraction under Groundwater Table Fluctuation Using the TMVOC Model

The effects of groundwater table fluctuation (GTF) on the remediation a petrochemically polluted riverside using soil vapor extraction (SVE) were investigated. migration and transformation benzene, toluene, ethylbenzene, o-xylene (BTEX) in cases natural attenuation, SVE without GTF, with GTF simulated TMVOC model. results showed that optimized well pressure influencing radius target site 0.90 atm 8 m, respectively. removal rates BTEX 11.49%, 85.16%, 97.33%, rate was maximized case amplitude 0.5 m to 1 m. benzene (99.99%), toluene (99.74%), ethylbenzene (96.37%), (94.72%) GTF. For mass losses gaseous (0.05 kg, 0.05 respectively) aqueous phases (5.46 5.87 consistent. However, loss non-aqueous phase liquid (NAPL) (155.13 kg) exceeded (135.41 kg). This is because positively affected both solubility volatility NAPL phase. With decreasing, flows gas pollutants increased by 25% along vertical section. At this stage, volatile organic compounds can be further improved increasing flow well.
