Thermoreact® - An Innovative Remediation Product for In-Situ Neutralization of Halogens, Sulphur, Phosphorus and Mercury during Thermal Desorption

Extended Abstract During In Situ Thermal Desorption, polluted soil (generally with TPH, PAH, Mercury, chlorinated solvents, etc.) is heated until vaporization of target contaminants is reached out of the soil. This results in the vaporisation of those pollutants, which are then drawn through perforated steel tubes, called vapor tubes, surrounded by gravel acting as a draining medium preventing the clogging of the tube perforations (by fine particles, sludge, etc.). These recovered vapours are then either treated in a vapour treatment unit or re-injected into the flame (in case of hydrocarbon pollution and heating with smart burners). after
