Soil Vapor Extraction (SVE) Unit

Soil Vapor Extraction (SVE) is a relatively simple process which physically separates contaminants from the soil. Contaminants are pulled to the surface as vapor is removed by applying a vacuum through a system of underground wells. Vapors are then either pushed through carbon filters to remove contaminants via the adsorption process or burned at a high temperature; leaving clean air to vent into the atmosphere.

Which vapors can be extracted by SVE?

Soil Vapor Extraction is used for soil contamination, basically any substance which has saturated the soil and needs to be removed—typically:

  • Solvents,
  • Hydrocarbons,
  • Other chemicals such as chloroform, or
  • Volatile organic compounds

Which industries benefit from using SVE?

A range of industries employ Soil Vapor Extraction as a form of soil remediation:

  • Oil & gas refining, production and pipeline,
  • Chemical,
  • Power,
  • Mineral mining,
  • Cement,
  • General manufacturing,
  • Environmental, and
  • Aerospace.

What is usually included in the Soil Vapor Extraction system?

A SVE system has the following standard components:

  • Vacuum Pump/Blower
  • Knock-out tank
  • Condensate Collection System
  • Control/Instrumentation System
  • Flow Measurement
  • GAC Scrubbers
  • Chart Recorder
  • Sparging Compressor

What are the different types of blowers available?

Along with your process conditions and available utilities on-site, your application will determine which type of blower is best suited for your needs:

  • Multistage regenerative
  • Centrifugal fan
  • Positive displacement rotary blower
  • Rotary claw
  • Rotary vane

What other options are available?

Conditions at your site will help determine the which options make the most sense. At McKenna we offer:

  • Explosion proof / Hazardous Rated
  • Containerized
  • Mobile/Trailer
  • Sparging
