Abstract

The vapor extraction system at a former waste disposal site was modeled in order to determine gas flow paths under the current operating condition and to evaluate a method for enhancing system operations. The model was three-dimensional finite-difference numerical model that simulates the movement of a fluid through porous media. The model was initially developed for groundwater flow, thus requiring appropriate conversions from hydraulic to pneumatic properties. The model was calibrated using pilot-study and full-scale operational data. Results showed that the model offers the visualization of gas flow paths under different operating scenarios, hence allowing the adjustment of extraction rates to eliminate stagnation zones and target the highest air velocities to the zones of highest VOC concentrations.
