A contaminated medium (such as soil and/or groundwater) contaminated with petrogenic and/or other organic contaminants such as petroleum hydrocarbons, light non-aqueous phase liquids (NAPLs), dense non-aqueous phase liquids (DNAPLs), persistent organic pollutants (i.e. sulfolane), chlorinated compounds, and volatile organic compounds, can be mixed with enhanced stimulators and be thermally remediated. The enhanced stimulators are heat induced to undergo exothermic reactions, which initiate a series of in-situ chemical reactions to such as to produce hydrogen gas. The hydrogen gas causes hydrocracking of heavy hydrocarbons to produce light hydrocarbons which can be recovered such as for future use.

A method and system to remediate soil containing PFAS compounds and organic carbon. Total organic carbon is reduced by heating the soil at a sufficient temperature and for a sufficient duration to reduce surface effects between the PFAS compounds and the organic carbon to permit evaporation and treatment of the PFAS compounds from the soil. A flexible helical heater is employed to heat the soil.

The present invention relates to a method for treating contaminated soil. A method for treating contaminated soil according to the present invention comprises: a flushing step of inserting a spraying rod including a nozzle into soil to spray a flushing liquid or an oxidizing liquid thereto; a first collection step of collecting floating material from the soil after the flushing step; a first phase separation step of separating the floating material collected in the first collection step into a liquid phase material and a solid phase material; a heating step of inserting a heating member into the solid fraction separated in the phase separation step to heat the solid fraction; a second collection step of collecting steam generated by the heating step; and a pyrolysis step of separating a gas phase material from the floating material from the floating material separated in the second collection step and performing heat treatment.

Sintered Wave Multi-Media Polarity Conversion Treatment Apparatus and Process is disclosed, which uses a non-destructive physiochemical PFAS vapor emissions treatment system to provide vacuum and vapor conveyance for 1) a Polarity Conversion Unit for non-destructive PFAS removal from soil, sludges, rechargeable galvanic filter media and objects, 2) a fluids treatment line for PFAS removal from water, brines, foams and colloids, and 3) an amphiphilic decontamination wand for PFAS removal from hard surfaces. The vapor emissions treatment system uses direct spray cooling to cool treatment gases where fluid chemistry causes pre-micellular aggregates/liquids crystals formation. Filtered aggregates are dried in a Brine Pot Evaporator for off-site disposal. Residual PFAS vapors are removed through a Vapor Phase Galvanic Separator where galvanic currents offer high energy interfaces of varying charges for monomeric PFAS self-assembly. The Polarity Conversion Unit assembly uses transportable flow through vessels, static geometry, high surface area, treatment gas temperature and velocity modulation to reduce thermal resistivity of the media. Treatment gas is sequentially routed around shaped vertical media beds where thermal energy disorganizes surface polarities (Gibbs free energy) disconnecting amphiphilic compounds/mixtures from the media. The fluids treatment line uses a Surface Excess Concentrator where a surface excess complex is created, removed and dried for off-site disposal. Treated bulk fluids exit from the bottom (below the surface) and are routed to the Aqueous Phase Galvanic Separator. Galvanic filter media is recharged in the Polarity Conversion Unit for reuse. Hard surfaces are decontaminated using the amphiphilic decontamination wand to disorganize surface polarity. Catalytic oxidation and granular activated carbon systems are also used to capture, destroy and measure classic contaminants and cleaved hydrocarbons from fluorinated precursors during treatment.

A closed-loop system and method for heating of target contaminant zones having environmental contaminants of concern present in the groundwater and the soil by thermal conduction, and subsequent enhancements of physical, biological and chemical processes to attenuate, remove and degrade contaminants in the target contaminant treatment zones, is disclosed. The system and method collects solar or other heat and transfers the heat via a closed-loop and a set of borehole exchangers to subsurface soil in the proximity of and/or directly to the target contaminant treatment zones. The target contaminant treatment zone may comprise contaminated soil, contaminated groundwater in an aquifer, or industrial waste comprising water and/or solids. Solar collectors or heat exchangers capturing waste heat from industrial processes may be used as the heat source.

A soil conditioner apparatus and method condition soil for compaction. The conditioner apparatus creates a heated stream of air directed toward the ground as the conditioner moves along the ground. A mixer on the conditioner mixes soil in the path of the heated air to dry the soil. Some embodiments of the mixer will propel the soil into the air in the stream of heated air. The conditioner can decrease moisture in the soil in the location where the soil will be compacted. In some embodiments, ambient air is introduced into the conditioning process by additional blowers. The mixer can also mix added soil and other additives to the soil in location. The conditioner apparatus may take the form of an apparatus towed by another vehicle, a set of towed apparatuses, an apparatus carried by another vehicle, or a self propelled vehicle having the operational elements of the soil conditioner.

A process for the remediation of contaminated particulate materials by the addition of an environmentally benign, carbonaceous fuel source in low concentration to enable or enhance smoldering combustion. The process may be applied to both in situ and ex situ treatments. In an ex situ smoldering process for the remediation of contaminated particulate materials in a continuous manner, contaminated feed is introduced near the top of a treatment unit and treated product emerges near the bottom. A smoldering front is maintained in the unit, fed by the fuel in the contaminated particulate material and a supply of combustion-supporting gas, such as air.
