Recovery of chlorinated solvents (CSs) as a free product is mainly based on the pumping and pumping/skimming approach. However, this technique is time consuming and does not allow significant recovery of CSs in the form of free product and its associated dissolved emissions. Our study focuses on the beneficial effects of thermal and chemical enhancements for recovering free product composed of heavy chlorinated compounds (Hexachlorobutadiene, Hexachloroethane, Perchloroethylene, Pentachlorobenzene, Trichloroethylene,…).
