| Title: |
Use Ultrasound To Identify Leaks. |
| Text: |
"Use Ultrasound to Identify Leaks. Some of the hardest leaks to find, and therefore among the larges leaks, are shutoff valves on open-ended lines that vent through an elevated stack. Ultrasound leak detectors are tuned to detect the high-frequency sounds associated with gas flowing through a valve that is not tightly closed. Lower-frequency background noises are filtered out. The magnitude of the sound corresponds to the magnitude of the leak. Ultrasound detectors can be applied to all in-service shutoff valves and pressure-relief, blowdown, starter-motor, and unit isolation valves. The cost of an ultrasound detector is approximately U.S. $250. Operating costs include the labor to locate and repair leaking valves, which may be as simple as tightening the valve. This emission reduction option is most cost-effective at facilities with a large number of valves." [see Table 2 and 3 in source document for costs, benefits and production characteristics] |
