leak detection

Optical gas-imaging is effective for visual identification of volatile organic compound (VOC) leaks. But it doesn't currently quantify the leak rate as required by regulations. This paper discusses work aimed at adding that quantification.

The authors have developed an active acoustic automatic leak-detection sonar designed to detect hydrocarbon leaks (mono- and multiphase oil and gas) at significant ranges, allowing coverage of wide areas from a single sensor.

A simple, practical, and reliable method to detect a gas leak under the conditions of unknown inlet or outlet gas rate, or unknown inlet or outlet pressure, is highly desirable. This paper discusses such a method.

Tube leaks present in a water-cooled sulfur recovery unit (SRU) condenser can lead to a variety of process issues, including corrosion and the oxidative formation of acidic species. This work devised a novel method to verify such leaks within a SRU condenser.
