VAPOR EXTRACTION UNIT

The Vapor Extraction Unit (VEU) was developed to remove residual gas quickly and safely, while monitoring the percent of gas in the moving air. It also helps in determining the location of a leak in an underground gas line, which has long posed difficult problems for gas line repair crews. HISTORY The conception of the Vapor Extraction Unit (VEU) was developed by Atmos Energy. Their challenge was to remove residual gas quickly and safely, while monitoring the percent of gas in the moving air. SOLUTION AND SUCCESS An Integral LEL monitor alarms the operator when dangerous gas concentrations are approached. A bypass valve then allows the operator to configure the VEU as necessary. The VEU was so successful at removing residual gas that different applications were explored. APPLICATIONS Current applications include the pinpointing of leaks on cast iron pipes and residual gas remediation. Some use the VEU purely for pinpointing leaks. Accurate pinpointing has made “keyhole technology” viable, reduced “dry holes,” and increased overall efficiency. Using the VEU for gas remediation allows businesses that may have residual gas underneath or around the foundation to promptly reopen – avoiding expensive downtime. HOW THE VEU TRAVELS Truck mounted units are used in the metroplex. Trailer mounted units are used in non-metro areas and are designed to be mobile from district to district.
