Soil Vapor Extraction with C3 Technology

Process Description | Power Requirements | Published Papers | GEO Brochure

C3 Soil vapor extraction systems are a combination of compressions, cryogenic cooling, and condensation combined with a proprietary regenerative adsorption technology that efficiently recovers volatile organic compounds (VOC's) from the soil vapor stream. Chemical is recovered as a non-aqueous phase liquid (NAPL) that is temporarily containerized for recycling or disposal. C3 soil vapor extraction systems recover 99.98% of VOC's present in the vapor stream.

New or custom modified systems can be manufactured in 8-12 weeks.

• Contaminated vapors are removed from soil vapor extraction wells by positive displacement blower, rotary claw, or rotary screw compressor.
• Entrained liquids are separated with the vapor liquid separator.
• Extracted air is compressed to 150 psi by reciprocating or rotary screw compressor and conditioned through a refrigerated chiller to further remove water and cool the stream to ambient temperatures.
• The vapor stream is further cooled to -45°F where the chemical constituents are condensed and separated from the vapor stream.
• The cleaned vapor stream is polished through a series of regenerative adsorbers that redirect any fugitive VOC's to the front of the system and then granular activated carbon.
