INTRODUCTION
The Vapor Extraction Unit (VEU) was designed to quickly and safely remove residual gas while monitoring the percentage of gas in the moving air. It also aids in identifying the location of leaks in underground gas lines, which has historically presented significant challenges for gas line repair crews.
HISTORY
The Vapor Extraction Unit (VEU) was conceived by Atmos Energy. Their primary goal was to effectively remove residual gas quickly while also monitoring the gas concentration in the air.
SOLUTION AND SUCCESS
An integral Lower Explosive Limit (LEL) monitor alerts the operator when gas concentrations approach hazardous levels. A bypass valve enables the operator to adjust the VEU as needed. The VEU's success in removing residual gas led to the exploration of various applications.
APPLICATIONS
Current applications of the VEU include locating leaks in cast iron pipes and remediating residual gas. Some users employ the VEU solely for leak detection. Its accurate pinpointing capabilities have made "keyhole technology" feasible, reduced the occurrence of "dry holes," and enhanced overall efficiency. Additionally, using the VEU for gas remediation allows businesses that may have residual gas beneath or around their foundations to reopen promptly, thereby avoiding costly downtime.
HOW THE VEU TRAVELS
Truck-mounted units are utilized in metropolitan areas, while trailer-mounted units serve non-metropolitan regions and are designed for mobility between districts.
