Soil Vapor Extraction

Environmental Remediation Application & Case Study

In soil vapor extraction remediation, the contaminated vapors are drawn from the soil via a vacuum pump and passed through an adsorber containing the appropriate adsorbent. The discharge temperature from the vacuum pump can be 140+ degrees F. In order to get the best capacity for adsorption of organics on the carbon and to prevent ignition of the organic-laden activated carbon, the adsorber is located on the suction side of the pump.

TIGG has soil vapor extraction adsorbers that can be used in soil vapor extraction applications. TIGG's soil vapor extraction adsorbers are available for sale or as rental remediation equipment.

TIGG- Activated Carbon Soil Vapor Extraction Remediation

TIGG Soil Vapor Extraction Remediation System

Soil Vapor Extraction Remediation at a Pacific Northwest Site :
The customer was removing chlorinated hydrocarbons from contaminated soil in a soil vapor extraction site. Consequently, a high concentration of hydrocarbons and high water vapor content off-gas was generated.

TIGG provided a demister with an automated condensate pump and two NB20 vapor phase adsorbers, each containing 20,000 lb. of carbon. On a weekly basis, TIGG managed on-site exchange and disposal of spent carbon.

The process soil vapor extraction solution was more economical than an incineration process due to the high chlorinated hydrocarbon content in the vapor steam.
