Challenge
The function of a Vapor Recovery Unit (VRU) is to capture dangerous vapors so that they are not released into the atmosphere. These vapors (mostly propane, butane, and pentane) are from volatile process fluids that are quick to escape through any small leaks. A gasoline terminal has in-process instrumentation, pipe joints, and valves subject to varying pressure and vibration that over time can develop leaks. In this case, a gauge had formed a leak that went undetected. To protect personnel and assets, the operator decided to install gas detection to monitor for vapor leaks. However, the location did not have a readily available power source for traditional wired gas detectors. Even if wiring could be accomplished, the operator was also worried about hazards related to substantial foot and vehicle traffic around the VRU.
Solution
The customer decided that wireless gas detection would be a preferential approach to augment as an additional IPL to the existing fire and gas system. Wireless made sense because the cost of wiring an independent gas detection system where there was no wiring available would be costly and time consuming. The Vanguard was chosen as an ideal candidate for this application to solve the problem over other wireless gas detectors due to its long battery life, use of an open wireless protocol (WirelessHART®), and general ease of use for the installers and maintenance personnel.
