G.E.O. Inc.

Overview | Features | Specifications

G.E.O. Inc. (G.E.O.) was founded in 1989 as an environmental remediation services supplier specializing in the manufacturing and operation of in-situ vapor extraction equipment for the removal of high concentrations volatile organic compounds (VOCs) from the subsurface. G.E.O. developed and continues to improve upon a proprietary off-gas treatment technology designed for highly efficient, cost-effective recovery of VOCs from soil vapor extraction (SVE) and multi-phase extraction (MPE) systems. The off-gas treatment technology developed by G.E.O. combines cryogenic-cooling and compression with regenerative adsorption technology (C3-Technology) that allows for condensation and recovery of the VOCs in the form of non-aqueous phase liquid (NAPL) and has repeatedly demonstrated substantial cost-savings and effectiveness when compared to GAC and ThermOx systems at many sites with high concentrations of VOCs including solvents and fuels.

C3 Technology

The C3 Technology (Patent Pending) developed by G.E.O. is a combination of cryogenic-cooling and compression processes with a proprietary regenerative adsorption technology that efficiently recovers volatile organic compounds (VOCs) from the off-gas vapor stream of soil vapor extraction (SVE) or dual phase extraction (DPE) systems. The chemical is recovered as a non-aqueous phase liquid (NAPL) that is temporarily containerized in appropriate vessels for recycling or proper disposal. Generally, greater than 99.8% of the VOCs are recovered from the vapor stream. Dependent upon the contaminant and State or local agency, final effluent may be polished with granular activated carbon (GAC).

Process Description

• Soil gas is drawn into the system and delivered to the air compressor by a 5- to 10-horsepower positive displacement blower.
• Entrained liquids are separated at the water knockout tank. Separated liquids are securely drummed and transported off-site or treated with GAC and discharged to the sewer or storm drain in accordance with all local and state regulatory requirements.
• Process air is compressed to approximately 150 pound per square inch (psi) by the compressor .
• Water vapor is removed from the process stream at the air-to-air heat exchangers as it is cooled to approximately 40° F temperature
• The vapor stream is further cooled to approximately -40° F in the refrigerated heat exchangers, where the majority of the chemical constituents are condensed and separated from the vapor stream.
• The vapor stream is then sent to the regenerative adsorber, which removes any residual chemical constituents and water vapor and directs it back to the inlet stream.

System effluent vapor stream [<10 parts per million by volume (PPMV)] is finally polished utilizing granular activated carbon (GAC) prior to discharge to atmosphere

New or custom modified systems can be manufactured in 6-8 weeks.
